Definitions

  • the present invention relates to a process for the manufacture of towels.
  • table provided with a sticky fastening element, in which an element is used having first and second opposite faces provided with adhesive or of an adhesive substance and in which a first of the said is applied faces of an element on a towel at least in the vicinity of one of its corners.
  • Such towels are useful for preventing the towel from falling to the ground and for ensuring that the towel is always correctly positioned relative to the user.
  • the towel is, for example, glued to the user's tie, shirt, etc.
  • the only way to make such towels is to manually apply double-sided self-adhesive elements, one towel at a time. The production of such towels is therefore tedious and uneconomical.
  • the towel thus obtained also often has many defects, such as incorrect placement of the element, poor presentation, poor application of the element on the towel, hence a risk of poor adhesion of the towel on a coat. of the user or a risk of tearing of the towel when the towel is torn off by the user.
  • a continuous adhesive strip is used or substantially continuous, having first and second faces opposite provided with glues or an adhesive substance, said strip being possibly made up of a series of separate fastening elements juxtaposed, said strip being provided with either a first continuous film of protection to cover the first side of the adhesive strip, i.e. second continuous or non-protective film to cover the second side of the sticky tape or either such first and second films.
  • first film having a surface adhering to the first face with force less adhesion than the adhesion strength of the first side on the towel or supports and / or a second film having a surface adhering to the second side with less adhesion force than the adhesion force of the first side on the towel or supports.
  • a pressure means the end of the strip whose first face is no longer protected by the first film on a napkin or support, and cut optionally partially the strip and / or the second film.
  • the traction or the movement of the first is controlled film for separating, at precise moments, said film from said strip, said moments corresponding substantially to the passage under the pressure medium of an adjacent location of a corner of a towel or a location of the support intended to become substantially the corner of a towel.
  • a controlled traction is exerted on said first film so that at least intermittently, the part of the first adjacent film to a towel or to the support successively follows a first movement of which a component is parallel to the advancement movement of the towels or supports and of which another component is perpendicular to the movement and directed to the support or towel, and a second movement of which a component is opposed to a advancement component towels or supports and of which another component is perpendicular to the forward movement in a direction opposite to the direction directed towards the support or towel.
  • the towels are moved or supports along a curved path, especially along a path corresponding to part of a cylinder. This does not bring the towel or support only in a specific place in relation to the place where we bring the part of the tape to stick on the support or towel.
  • the first movement of the film extends in a direction at an angle between 5 and 75 °, from advantageously between 15 and 60 °, preferably less than 45 °, relative in the plane in which the towels or supports move or in relation to the plane tangent to the curved path of the towels or support at the point where a sticky element is applied
  • the said strip is guided to a towel or a support.
  • a first film and / or a second film which has a width greater than the width of the strip.
  • a continuous adhesive strip is used, having, between its lateral edges, a substantially constant width, as well as first and second opposite faces provided with glues or an adhesive substance, said strip being provided with a first continuous protective film to cover the first face of the adhesive strip and a second continuous protective film to cover the second face of the adhesive strip, said films having a width greater than the width of the strip, while said strip is placed in relation to said films so that for each film, the lateral parts thereof are not covered by the strip.
  • the strip and the films have cutouts, said cutouts being such that they extend from a lateral edge of the strip to the opposite lateral edge thereof, over the entire thickness of said strip and qu 'They do not extend completely into the lateral parts of the films which are not covered by the strip.
  • the towels or supports intended to form one or more towels in a direction of advance, and to exert a controlled traction on said first film and on said second film so that at least intermittently, the part of the first film adjacent to a towel or the support successively follows a first movement of which at least one component is parallel to a component of the movement of advancement of the towels or supports and a second movement a component of which is opposite to a component for advancing the towels or supports, so as to guide and bring one end of the strip towards a towel or a support during said first movement and so as to separate the film from the strip substantially during of the movement of the film movement in the second movement, a component of which is opposed to a component for advancing the towels or supports , and so that at least the part of the second film adjacent to the napkin or to the support successively follows a first movement comprising a component parallel to the advancing movement and a component perpendicular to the advancing movement and a second movement parallel to the movement d '
  • the end of the strip is applied by means of pressure to a towel or support, and the traction or movement of the first film and the second film is controlled to separate into precise moments said first film of said strip and to bring the end of the strip by the second film towards the towel or support, said moments corresponding substantially to the passage under the pressure means of an adjacent location of a corner a towel or a support location intended to become substantially the corner of a towel.
  • a detachable support advantageously having a dimension greater than the surface of the element.
  • cuts are made in the strip and the supports so that said cuts are such that they extend from a side edge of the strip to the opposite side edge of the latter, over the entire thickness of said strip and that they do not extend completely in the side parts of the films which are not covered by the band.
  • Controlled traction is exerted on said first film and on said second film or we control the movement of the films so that at least intermittently, the part of the first film adjacent to a towel or the support successively follows a first movement of which at least one component is parallel to a component of the advancement movement of towels or supports and a second movement of which a component is opposite to a advancement component of the napkins or supports, so to guide and bring one end of the strip to a towel or support during said first movement and so as to separate the film from the strip noticeably during the movement of the film in the second movement of which a component is opposed to a advancement component towels or supports, and so that at least the part of the second film adjacent to the towel or support successively follows a first movement including a component parallel to the movement and a component perpendicular to the advancing movement and a second movement parallel to the advancing movement.
  • elements or parts of tape are applied to a substantially continuous support, the second face is then protected by a detachable support if necessary, and finally said support is cut and folded into individual towels .
  • parts of strips intended to serve as fastening elements for at least two towels are applied, the second face of the strip part is then protected if necessary by means of a detachable support of larger surface area than that of the strip part, and finally the support is cut, the strip parts and the detachable supports, before folding the supports cut into towels (in four for example).
  • the means for applying the end of the strip is a cylinder mounted on a rotation shaft so that it can rotate freely.
  • the guide means advantageously consist of at least two rollers between which the strip and the second film are stretched and a ramp or a deflection roller arranged in relation to the two rollers so that the first film is stretched between one of said rollers and said ramp or deflection roller, said deflection roller or ramp serving as a means for separating the first film Of the band.
  • the guide roller serving to support the second film and which is adjacent to the means carrying the towels or support has a diameter suitable for separating the second film from the strip.
  • FIG. 1 shows a strip 1 having opposite faces 2,3 provided with a layer of adhesive, said faces 2.3 being covered by films 4.5 of protection.
  • the strip 1 has a width L less than the width LL of movies. Cutouts 6 extend through the strip and film assembly. The strip 1 is thus cut into separate elements 10,11. The cuts 6 do not extend into the side portions 40.50 of the films 4.5, so that despite the cuts, the films serve as a means of holding the strip together and means for moving the strip by pulling on the first film or on the second film.
  • the machine or more exactly the machine head to apply on the support 100 of the elements 10, 11 is shown diagrammatically in FIG. 2.
  • the support 100 is carried by a rotary drum 101 (arrow R). This drum rotary ensures an at least partially circular movement to the support by compared to head 102.
  • the head 102 is associated with a roller 130, either able to rotate freely, or driven by a motor (for example so that the tangential speed T1 of the roller 130 corresponds approximately to the tangential speed T2 of the drum 101), this roller 130 being intended for applying or pressing the sticky element 10 on the support 100 carried by the drum 100.
  • the film 4 passes successively on the roller 104, on the cylinder 114, on the deflection roller 105 and on roller 110, before winding on the reel 112.
  • the film 5 passes successively on the roller 104 (with interposition of film 4 and strip 1), on the guide ramp 106 and on the return cylinder 115, before being wound on the reel 112.
  • the strip 1, which consists of a series of separate elements 10,11 juxtaposed, pass successively on roller 104 with interposition of film 4, on the cylinder 114 with interposition of the film 4, on the ramp and the cylinder 115 with interposition of film 5, on roller 105 with interposition of film 4, and finally between the roller 130 and the drum 101.
  • the ramp 106, the cylinder 115 and the roller 105 brings the end of the strip 1 towards the drum according to a movement comprising a component M1 parallel to the tangential plane at drum at the point of PC contact of the tape with the support and directed into the direction of advancement (R) of the support, and an M2 component perpendicular to said tangential plane.
  • the movement of the strip is carried out in one direction making an angle ⁇ with said tangential plane, this angle being about 15-30 °.
  • the return cylinder 115 along which the film 5 slides when a pull is exerted on it during the winding of the film by the reel 112, serves as means to separate the film 4 from the strip 1, so that the sticky side 3 of the strip is able to stick to the support 100 as soon as the free end of element 10 touches the support.
  • a feed angle of the strip of the order of 15-30 ° ensures progressive contact of the element on the support.
  • Roll 105 ensures adequate separation of film 5 from the strip. However, when element 10 has one end glued to the support, element 10 is driven by the support 100 set in motion, while the reel 112 no longer exerts traction on the film 5.
  • the jack 121 is activated to move the roller 105 away from the drum, while that the reel 111 is controlled to ensure that the length of film 4 made free by the movement of the roller 105.
  • the roller 105 When an element must be applied to the support, the roller 105 is in a first in a distant state of the drum 101, so that by the traction exerted by the reels 111,112 the two faces of the element 10 are free of films near the free end. Once about 1 ⁇ 4 to 1 ⁇ 2 of the length of the element is free from the films 4.5, the jack 121 is activated to bring roller 105 closer to the drum and to correctly guide the element to the support.
  • the cylinder 114 serves as a means to prevent or allow movement of the strip along the ramp 106.
  • a brake acts on the shaft of rotation on which the cylinder 114. is mounted.
  • this brake is activated, element 11 adjacent to element 10 which is being applied to the support 100 is compressed between cylinder 114 and ramp 106.
  • this brake is sufficient to oppose the traction exerted by the reels, so that the part of the strip located between the roller 104 and the cylinder 114 does not undergo displacement. If the brake is sufficient, it is possible to use reels now continuously pulling on the part of the films located between the cylinder 114 and a reel. In this case the intermittently sticking element on the support 100 may be obtained by controlling the brake on cylinder 114.
  • the roller 105 and the cylinder 115 have a diameter adapted to favor the release of films from the tape.
  • This diameter is for example very small of so the change of direction of the films in relation to the tape is abrupt, i.e. takes place in an area corresponding to less than 1/5 of the length of an element, preferably less than 1/10 of said length.
  • FIG. 5 schematically shows an installation comprising a head 102 as shown in Figure 2.
  • This installation comprises a reel 200 of a reel of tissue-paper for napkins, support rollers 201 for bringing the sheet of tissue paper on the rotary support 101, a device 202 for placing on the sticky elements carried by 1 tissue-paper sheet a removable protective element (advantageously pre-printed), one or more return rollers 203 to bring the sheet to a unit 204 for cutting and folding the sheet into a towel.
  • the film 5 carries a series of sticky elements 10.11 on each of its faces.
  • Each sticky element 10,11 being provided with a detachable protective element (of width greater than that of the pre-cut adhesive strip) on its face opposite to that facing film 5.
  • a machine of the type shown in FIG. 2, but simplified, can be used. If the film 5 is still pulled by a rewinder 12, the elements are brought into contact with a towel or a support intended for form towels using a slide in which part slides of the protective element which is not in contact with the sticky element 10.
  • This slide is advantageously provided with a means of gripping of the protective element, said element being set in motion for example rotation to apply the element on the towel or support.
  • This gripping means is for example a half-cylinder 301 associated with a drum 302 rotated by a motor, the space between the drum and the half cylinder being small enough that the protective element can be driven by the drum.
  • the drum is advantageously provided with teeth or protrusions to increase the adhesion of the protective element.
  • An applicator roller 300 (driven in rotation by a motor) can then be provided to firmly apply the sticky element to the towel.
  • Such an element application head is shown diagrammatically in FIGS. 6 and 7.
  • the film 5 is removed by a ramp 106 similar to that of FIG. 2.
  • a slide comprising two dishes 1001,1002 approaching one towards the other the closer we get to the drum is used.
