Definitions

  • panty hose are made by assembling by sewing the individual parts which form them (leg pieces, body piece, and optionally - but very frequently - a so-called gusset in the region of the crutch), and which are knitted beforehand separately from each other.
  • a first object of the invention concerns a method for the formation of a garment of the panty hose type, with two leg pieces and a body piece, directly by means of a circular machine for knitwear and in particular stockings with a needle cylinder performing a continuous and/or alternating rotational movement.
  • a second object of the invention concerns a garment obtained with the above method.
  • a third object of the invention includes a circular machine for stockings and the like for implementing the above method, as well as devices to be combined with said machine.
  • a particular development of the invention consists in a new processing method - applicable to a single-cylinder circular knitting machine - which allows the production in a single uninterrupted operation on a machine of this type, by means of minor modifications, of an article such as panty hose or briefs or shorts or the like, without assembling seams, the body piece having a suitable height and any desired width considered necessary.
  • this method consists of six steps: - First step: formation, according to the system ordinarily used, of one of the two leg pieces of the garment;
  • Second step formation of a first side portion of the body piece located above said first leg piece already formed, by means of the gradual reduction in the number of working needles, with exclusion from operation of a needle after a certain number of rows of stitches, depending on the dimensions which are to be given to the body piece and the quality of the yarn, with the formation, along the upper part of this portion of the body piece, of a double fabric edge, also obtained by the needles of the cylinder of the machine with the aid of sinkers.
  • the body piece is provided with the heightwise and widthwise dimensions, which are considered necessary and desirable, by means of the formation of said central part with stitches which are looser, i.e. untensioned and "slackened", and therefore wider, obtained with a greater length of the stroke of the needles.
  • a double fabric edge also obtained by the needles of the machine cylinder with the aid of sinkers, is simultaneously formed along the upper circumference or waistline of said part of the garment;
  • steps 1 to 6 will be limited to the sole formation of the side portions of the body piece.
  • Figs. 13, 13A, 13B and 13C show a detail and enlarged features of the knitted fabrics in the zone of the body piece;
  • Fig. 14 shows a variant of Fig. 13C;
  • Figs. 15 to 21 show, similar to Figs. 3,4,6,7,8,9 and 10, the steps of the method in which the garment is also provided with a tubular double-edge finish along the waistline;
  • Figs. 22 to 26 show various - plan and perspective - views of a device for forming a reinforcement during continuous rotational operation for the formation of side portions of the body piece;
  • Figs. 27 to 31 show a cross-sectional view and various perspective views of a device for the formation of a finish at the ends of the central band of the body piece, in alignment with the tubular double-edge finishes of Figs. 15 to 21 ;
  • Figs. 32 to 36 show the steps for formation of the finish according to
  • Figs. 1 to 12 illustrate the steps of the method for forming leg pieces and body piece of the garment of the panty hose type, independently of the finishes along the edge which correspond to the waistline.
  • Fig. 1 shows the formation of a first leg piece 1 with all the needles 2 of the needle cylinder of a circular knitting machine, of which A1 , A2, AO and A10 indicate some of the characteristic points on the needle circumference.
  • A1 , A2, AO and A10 indicate some of the characteristic points on the needle circumference.
  • the body piece comprises a first side portion 3 (formed with a main yarn 30), an intermediate band 7 (formed with a main yarn 70) which extends along the so-called crutch line, and a second side portion 9 symmetrical with the portion 3; the second leg piece 10 is then formed.
  • the needles of the arc A1 , A0, A2 are used and the operation continues with increments until all the needles on the needle circumference of the machine are used, and the formation of the second leg piece 10 is then performed, with formation of the fabric in the opposite direction to that in which the first leg piece 1 is formed, namely from the body piece towards the end of the leg piece 10, while the first leg piece 1 is made starting from the tip, i.e. from the foot towards the body piece.
  • the first side portion 3 of the body piece commences, initiating a gradual reduction in the working needles, from the point A10 of the needle circumference, gradually reducing the working needles for formation of said portion 3 with the exclusion of a needle after every n rows of stitches, for example after every four rows of stitches.
  • a reduced profile 5 of the fabric of the first side portion 3 is thus obtained; the profile 5 extends, at the end of processing of the portion 3, as can be seen from the sequence of Figs. 1 , 2 and 3, as far as the minimum arc A1 , AO, A2 of working needles for the formation of said first side portion 3, i.e.
  • FIG. 5 shows the article being formed, as in the portion obtained during the step in Fig. 4, but shown in the condition in which this portion takes in the worn article.
  • formation - with a main yarn 70 - of the central band of fabric 7 commences, which band once the article is finished and worn, extends along the crutch line of the finished garment; this central band is formed with the needles of the arc A1 , A10, A2 performing a continuous (or optionally alternating) movement.
  • the band 7 is formed with relatively very wide stitches, starting with a row of stitches 7A which engages with the stitch loops B1 , B2, B3, B4, etc.
  • the stitches of the band 7 will each have a width corresponding to that of the stitches of four adjacent partial rows of the portions 3 and 9. It may be noted in particular from Fig..6 that, during formation of the band 7, the rows of stitches which form it extend perpendicularly to the rows of stitches which formed the leg piece 1 and the first side portion 3.
  • the number of rows of stitches which form the band 7 is undefined in the sense that rows of stitches may be formed in any desired number in order to obtain formation of the body piece in combination with the two side portions 3 and 9.
  • the sole constraint to which the formation of the band 7 of fabric is subject is the number of needles of the arc A1 , A10, A2, the needles of which are intended for the formation of said band 7; this is equivalent - by way of difference - to a corresponding number of needles which are assigned for formation of the end edge 3A and the corresponding leading edge 9A of the two side portions 3 and 9, respectively, which together with the widthwise extension of the central band 7 and in particular the end edges 7X, 7Y of the rows of stitches of the central band 7 must form the waistline.
  • the band 7 may be made with a yarn 70 different from that with which the side portions 3 and 9 are formed, this yarn being able to possess a greater coarseness and/or suitable elasticity, so as to obtain the desired result for the purposes of wearability of the finished garment.
  • the band 7 may be finished along the terminal lines 7X and 7Y in any suitable manner as better explained in an example described below, and the end zones of the band 7, adjacent to the end lines 7X may be formed with an additional yarn or with a yarn having different characteristics, in particular, as regards coarseness and elasticity, compared to the rest of the band 7.
  • the band 7 may also be formed with a suitable gusset such as that indicated by 7T, in an intermediate position along the overall extension of said band 7, in order to reinforce - as frequently required for garments of the kind in question - the bottom zone of said band 7 which extends along the crutch line.
  • the needles of the arc A1 , A10, A2 form the row of end stitches 7B of said band 7, which is symmetrical with respect to the first row of stitches 7A of the band 7 which have engaged with the loops B1 , B2, B3, B4, etc.
  • Fig. 6 shows the formation of the second side portion 9 of the body piece, initially - by means of the needles of the arc A1 , AO, A2 - with the edge 9A, which may be equipped with a suitable finish similar to that which may be envisaged along the edge 3A of the first side portion 3, this finish being performed first in order to start off the formation of said second side portion 9.
  • Fig. 7 shows the formation of the leading end 9A (which may be equipped with a preliminary finish) and the start of formation of the fabric of said second side portion 9 with increments of the rows of stitches of the fabric 9 along the line 8, i.e. with the insertion of additional needles at the two ends of the arc A1 , AO, A2, i.e.
  • the formation of said second portion is performed by increasing gradually the needles from the point A1 to the point A10 and from the point A2 to the point A10 and introducing operation of a needle of these arcs after the formation of n rows of fabric of the second end portion 9, in practice for example introducing a needle at each end of the arc of needles instantaneously in operation, every four rows of stitches formed with the needles already in operation.
  • a profile 8 joining together the fabric of the band 7 (along the row of stitches 7B) and the fabric of the second side portion 9 is thus formed; this profile 8 corresponds to and is symmetrical with the profile 5 already formed.
  • the two profiles 5 and 8 which flank the central band 7 are identical and in particular both these two profiles are defined by eyelets, i.e.
  • the arc of needles A1 , A0, A2 should be increased to the detriment of the number of needles of the arc A1 , A10, A2 with which the rows of stitches of the band 7 are formed; however, the overall extension along the crutch line of the band 7 may be corrected - if the number of needles which form the rows of said band 7 must be reduced - by increasing the dimension of the stitches of the rows forming the band 7 itself and modifying the elasticity characteristics of the yarn or yarns with which said band 7 is made. It should also be taken into account that the number of rows with which the band 7 is formed, i.e.
  • the width which may be imparted to the band 7 is not dependent upon any circumstance which may be negative with regard to the form of the two side portions 3 and 9. It is also worth considering that, during formation of the band 7, the size of the stitches of the rows of stitches which form said band 7 may be modified along the extension of the band itself; it is possible to envisage, for example - as required - an increase in the size of the stitches of the band 7 towards the ends 7X,7Y thereof and a reduction in the central zone between the points 5o and 8o of said band 7; this reduction in width may also be obtained using a working process of the "retained stitch" type.
  • the terminal end 3A of the first side portion 3 of the body piece and the leading end 9A of the second side portion 9 of the body piece form part of the waistline of the knitted garment or panty hose formed in the manner described and a finish for these ends 3A and 9A is appropriate.
  • This may be obtained with the formation of a suitable edge which may be elasticized with a varied configuration of the end rows along the end 3A of the portion 3 and the first rows along the end 9A of the portion 9 and/or with the presence of additional yarns which are for example elasticized along said end edges 3A and 9A.
  • a so-called double edge or tubular edge with techniques which are known in the field and which may be implemented both at the end and the start of formation of a fabric.
  • Figs. 15 to 21 are similar to Figs. 3, 4, 6, 7, 8, 9, 10, but differ from them because these Figs. 15 to 21 show in a particularly clear manner the presence of a tubular finishing edge 3X along the final edge 3A of the first side portion 3 and an initial double edge 9X along the initial line 9a of the side portion 9 of the garment body piece.
  • finish such as 3X and 9X or other equivalents is obtainable whatever the manner in which the two side portions 3 and 9 of the body piece are formed, which side pieces 3 and 9 may be formed with a continuous rotational movement of the needle cylinder or with an alternating movement of the needle cylinder.
  • a similar finish may also be formed along the end edges 7X and 7Y of the central band 7, extending along the crutch of the garment, which may also be performed with a continuous rotational or alternating movement of the needle cylinder.
  • the side portions 3 and 9 of the body piece may be formed with a continuous movement of the needle cylinder or with an alternating movement of the needle cylinder.
  • the decrements it is envisaged inserting, for the formation of the last stitches of each of the gradually reduced partial rows of the side portion 3, in addition to the main yarn 30, an additional yarn 31 which is arranged alongside the main yarn so as to form the fabric of the portion 3 for, for example, the four end stitches of the gradually reduced rows of this fabric;
  • the additional yarn 31 is supplied with a yarn guide which is made to move rapidly forwards and backwards on the front of the needles in the region, for example, of the four final needles assigned at a particular instant for the formation of a partial row in which the reinforcement must be performed; in this way the additional yarn 31 engages with the four end loops together with the main yarn, is then rapidly transferred with a section 31 A onto the front of said four needles which are engaged with it and is then engaged a second time by the same four needles and is finally cut together with the main yarn when the needle cylinder terminates processing of the row of stitches in question of the portion 3A; this is repeated at the start of formation of each successive row.
  • these reinforcements obtained with the additional yarn 31 which is positioned so as to be combined with the main yarn along the - for example - four end stitches of each partial row prevent the stitches of the partial rows of the portion 3 from otherwise becoming unraveled since the main yarn is gradually cut along the profiles 5.
  • the four stitches reinforced with the additional yarn 31 commence at the point 5o, i.e. at the point AO of the needle circumference when the decrements start, i.e.
  • a device such as that shown in Figs. 22 to 26 may be envisaged. These show a device which is combined with the needle cylinder of the knitting machine which rotates with a continuous movement and in which the main yarn is cut at the ends of the partial rows. With the yarn 31 in addition to the main yarn, the formation of the end stitches of the partial rows is performed, in order to ensure fastening of the stitches to the ends of the partial rows which are gradually reduced along the profiles 5 and 8 which flank the central band 7 extending along the crutch line.
  • the device is designed to perform the stitches with the additional yarn 31 in the region of the four end stitches of the rows extending in the zones adjacent to the said profiles 5 and 8.
  • 201 indicates the so-called sinker disk or plate, underneath which the needle cylinder is located.
  • 103 indicates the needles of a group of four needles which are assigned at a particular instant for performing the four last end stitches of a partial row of stitches of the side portion 3 of the body piece, where the decrements are performed and where the yarns which form said partial rows are cut; the rotation of the needle cylinder is indicated by the arrow f 101.
  • the needle cylinder there is a vertically extending support structure 105 with a lower fixed base 105A arranged underneath an upper arm 105B.
  • a pivot pin 107 about which the lever 109A of a pivoting yarn guide 109 is able to pivot, said yarn guide being able to perform deviating movements as can be seen from a comparison of Figs. 22, 23, 24.
  • the arm 109A is actuated via an end member 109B by a connecting rod 110 which is in turn operated by a crank 112 integral with a vertical shaft 114 extending in the structure 105.
  • the shaft 114 has, underneath and integral with it (Figs. 24, 26), a sprocket wheel 116 capable of meshing with an internally toothed segment 118 which is mounted on a feeler 120 which pivots about a pivot pin 122 mounted on the base 105A.
  • the feeler 120 with its end member 120A having a lateral extension, is able to be acted on by the four butts 103A of the four needles 103 which at a particular instant - by means of electronic sensors which are known per se - are displaced to a level such as to interfere with said end member 120A and engage with the yarn 31 supplied by the yarn guide 109, when these needles 103 must form the four reinforced end stitches of the individual partial rows which form the side portion 3 of the body piece.
  • the yarn guide 109 is located in the position shown in Fig.
  • the feeler 120A, 120 is displaced suddenly by the first of the butts 103A of the needles 103 which have just finished operating; in this way this butt 103A and the other successive butts displace the feeler 120A, 120 through a limited angle about the shaft 122 as far as the position shown in Fig.
  • the displacement of the feeler 120, 120A about the shaft 22 causes the corresponding angular displacement of the toothed segment 118 and therefore a reverse and greater angular rotation of the sprocket wheel 116 which meshes with this toothed segment;
  • the rotation of the sprocket wheel 116 causes the corresponding rotation of the shaft 114 with which said sprocket wheel is integral;
  • the shaft 114 in turn causes, by means of the hinged joint 112, 110, 109B, the sudden rotation of the arm 109A and therefore the yarn guide 109 from the position shown in Fig. 22 into the position shown in Fig.
  • the feeler 120, 120A having lost contact with the butts 103A of the four needles which were inserted at the level of the feeler itself in order to perform reinforcement with the yarn 131.
  • the yarn 131 was able to form, together with the main yarn 30 for formation of the side portion 3, the four end stitches of each final row, until it is cut together with the main yarn 30 after formation of said reinforcement 31 , 31 A in the four end stitches.
  • the group of four needles 103 which performed, for four rows, the formation of the reinforcement preventing unraveling of the rows of the main yarn is replaced, eliminating the last of the four needles which worked previously and after inserting ahead of them a further needle for forming the new group of four needles displaced by one position, so as to allow the yarn 31 , 31 A to be able to create the four end stitches at the ends of the successive four rows which are formed after reduction by one needle along the profile 5 for formation of the side portion 3. Formation continues along the whole of the profile 5 from the start of the reductions in the stitches of the partial rows to the end of formation of the side portion 3, i.e. along the whole arc from AO to A2 and from AO to A1. The operation described is performed at the two ends of each partial row of the portion 3.
  • Figs. 27 to 31 show in schematic form the disk or plate 201 of the sinkers 203, which is positioned in a conventional manner coaxially and immediately above the end of the needle cylinder, so as to co-operate with the needles themselves.

  • said specific sinker(s) 203 causing projection or retraction, is obtained with conventional systems, by providing above the disk or plate 201 cams such as that 230 and 232 operated by electronic systems able to operate at the appropriate time and temporarily the butt of the specific sinker(s) which must be made to project temporarily for the function which is described hereinbelow (in order to form the finish with reinforcement at the ends 7X and 7Y of the central band 7).
  • Said or each of said specific sinkers may thus project, be displaced angularly (due to the angulation imparted by the Z-shaped slit 10A,B,C), be retracted and return angularly into the original angular position, one or more times and at the appropriate time according to the program.
