Definitions

  • the present invention relates to a lancet holder which forms part of a double-piece loom and is provided as a carrier for a large number of lancets which extend between the upper and lower tissues in order to keep the designated tissues apart at a certain distance, whereby these In this way, lancets determine the pile height of these tissues.
  • each lancet consists of an elongated piece of flat steel of small thickness e and a height h - which is twice the desired pole height on each tissue.
  • One outer end of each lancet is provided with an elongated, gap-like opening which extends in the longitudinal direction of the lancet and traverses it, the opening in the side faces emerging from the height h.
  • each lancet ends in the form of a point by uniformly and symmetrically reducing the height h of the two surfaces.
  • These lancets are arranged with their surfaces of height h close to each other and, each extending in the warp direction, vertically so that they are between the woven upper and lower part; they are carried by a horizontal profile that extends through the elongated openings of all lancets and is rigidly attached to the loom, running in the weft direction.
  • all lancets are parallel to one another and are pushed close together on the profile.
  • the length of each elongated opening is greater than the width of the horizontal profile that passes through these openings.
  • Each lancet is also the length that the elongated opening is provided with a slight bend in one direction provided, which runs perpendicular to the side surfaces according to a symmetrical circular arc, so that the two outer ends lie on the same longitudinal axis.
  • the edge of each elongated opening, which is supported on the profile is bent laterally in accordance with an arc of a circle and consequently forms an aerofoil located along one side outside the center of gravity, which prevents the lancet from easily tilting on the supporting profile.
  • the designated profile, which carries the lancets has the shape of a crossbar and is carried one after the other with the aid of holders which each enclose it along the underside and at the front (fabric side). These holders are also attached to another profile with the help of bolts or similar aids.
  • This profile has the shape of an inverted U and is connected to the frame of the loom.
  • Another disadvantage is that the lancets can move in the longitudinal direction of the support profile on that profile and contract during weaving.
  • Yet another disadvantage of this device is the fact that a sufficient number of holders - distributed over the length of the profile - must be provided in order to prevent this profile from being influenced in a vertical surface and under the influence of its own weight and the weight of the lancets under the influence of the tensile force which the lancets overcome as a result of the further movement of the fabric, it deflects in a horizontal surface in the warp direction.
  • the aim of the invention is a lancet holder for a double-piece loom, in which the above-mentioned disadvantages cannot occur, in other words, in which the lancets cannot move and cannot tilt laterally, and in which the yarns which are close underneath or run above the device, can individually come into contact with smooth and rounded surfaces and edges, whereby bending of the profile is prevented both in a vertical surface and in a horizontal surface without the use of special holders or fastening aids, which the profile on different Capture places regarding the loom.
  • the object of the invention is a lancet holder which, as in the known device described above, consists of a lath-shaped profile onto which the lancets are pushed, each lancet having an elongated opening through which the designated profile extends, but which has the characteristic number has that a comb preferably made of metal extends parallel to this profile at the height of these lancets close to the lath-shaped profile.
  • a comb preferably made of metal extends parallel to this profile at the height of these lancets close to the lath-shaped profile.
  • There is a gap between every two vertical teeth of this comb the width of which is a little larger than the thickness e of a lancet, while the space between two closely spaced columns corresponds to the distance between two closely spaced columns in the reed, or a multiple thereof that distance is.
  • the width of the gap between two teeth is chosen such that a lancet can be in that gap when its sides are vertical and extend perpendicular to the longitudinal direction of the
  • the comb is arranged in such a way that all lancets can run between two teeth of the comb.
  • the lancet holder according to the invention is also characterized in that the back of all lancets - the part which is provided with a gap and which is pushed behind the comb on the lath-shaped profile - is enclosed by an enveloping wall.
  • This wall runs at least above and below the rearmost outer end of the lancets, which sit on the lath-shaped profile - over its entire length - and can also form a vertical rear wall which extends downwards along the rearmost outer ends of the lancets, while this wall extends longitudinally below and has front edges adjoining the comb at the top and the vertical distance between those foremost edges must be greater than the height h of the lancets which extend between the comb teeth from the space enclosed by the wall.
  • connection aids - such as bolts, screws and similar aids - between the various individual parts along the back of the lancet holder when looking from the direction of the tissue, and thereby that the outer surfaces of the lancet holder are smooth and have rounded edges.
  • the lancet holder according to the invention is characterized in that the comb is connected to at least one edge of the surrounding wall by means of bolts, screws or similar aids, and in that an upright edge of the wall surrounding the bottom serves as a supporting surface for the lancets, while the top section of the Wall due to its connection with bolts or similar tools forms an easily removable cover of the enclosed space.
  • An advantage of the lancet holder according to the invention lies in the fact that on the one hand the lath-shaped profile and the rear outer ends of the lancets pushed onto it are completely enclosed, and on the other hand the outside of the enclosing walls are smooth and rounded and possibly bolts, screws or the like Parts run below, which prevents the yarn from stalling.
  • Another advantage of the lancet holder according to the invention lies in the fact that the comb ensures that the lancets do not move and contract and cannot tip over, so that, among other things, their laterally curved embodiment is superfluous.
  • Yet another advantage of the lancet holder according to the invention lies in the fact that the surrounding wall forms, as it were, a can in which the profile and the comb are fastened, whereby the lancets are carried on the one hand by the profile and on the other hand on an upright edge of the surrounding Rest wall, so that due to the rigidity of the surrounding wall, the profile is prevented from sagging in a vertical surface.
  • the lancet holder according to the invention consists of a lath-shaped profile (1) which is fastened to the frame of the loom horizontally in the weft direction using known aids. All lancets (2) are pushed onto this lath-like profile (1), so that it is located in the rearmost outer ends of all lancets (2) and runs through their gap-shaped openings (3).
  • the lancet holder according to the invention is further characterized in that a comb (4) is arranged on the lath-shaped profile (1) at the height of the lancets (2).
  • This comb (4) consists of a lower, continuous section (5) which is provided with openings (6) for fastening bolts (7), while vertical teeth (8) of the same length and thickness run on this section (5), a space is provided between each two teeth, which is a little wider than the thickness e of a lancet (2).
  • This comb (4) is arranged vertically on the lath-shaped profile (1), so that each lancet (2) can extend between two teeth (8) located close to one another.
  • the lancets (2) stand in a direction perpendicular to that of the comb (4).
  • the length of the comb (4) is chosen such that all lancets (2) are on the total length of the lath-shaped profile (1) are present, can extend between the teeth (8) of the comb (4).
  • the lancet holder according to the invention is characterized in that it consists of two enclosing profiles (9) and (10) which are identical in shape.
  • the shape of these profiles is that of an elongated C with a short leg (9 ') and (10') and a longer leg (9 '') and (10 '').
  • Both profiles (9) and (10) are connected to one another with the aid of bolts (11), screws or similar aids - the long legs (9 '') and (10 '') lying vertically against one another -.
  • These profiles have the same length and are placed horizontally one above the other, the channel-shaped edges facing each other; consequently they form an enclosing wall.
  • the upper and lower surface of the enclosing wall is formed by the horizontal sections of the profiles (9) and (10), while the rearmost, vertical surface is formed by the long legs (9 '') and (10 ') which are placed against one another and connected ') of the profiles (9) and (10) is formed.
  • the front of the enclosed space is open between the vertical, short legs (9 ') and (10') of the profiles (9) and (10) which are directed towards each other.
  • the interconnected profiles (9) and (10) are now arranged and fastened to the loom in such a way that the lath-shaped profile (1) over its entire length and consequently also all the rearmost ends of the pushed-on lancets (2) within the profile ( 9) and (10) enclosed space.
  • the lancets (2) which extend further forward, leave the enclosed space on the open front, which must therefore be higher than the height h of a lancet (2).
  • the lancets (2) run between the teeth (8) of the comb (4), while the latter with its continuous section (5) - over the entire length - against the side of the lower, upright, short leg (9 ') - on the inside of the enclosed space - and is fastened to it by means of bolts (7) or similar means, which through the openings (6) in the continuous section (5) of the comb (4th ) go through and sit horizontally in the side of the short leg (9 ') of the lower enclosing profile (9).
  • the upper ends of the teeth (8) lie against the side of the short leg (10 ') of the upper profile (10) and at the same time along the inside of the enclosed space.
  • the lancet holder according to the invention is characterized in that the space between two columns of the comb (4) which are located close to one another corresponds to the distance between two columns of the reed of the loom or is a multiple of this distance.
  • Another feature of the lancet holder according to the invention is that the walls of the enclosing profiles (9) and (10) are smooth and that their corners are rounded, and furthermore that the connecting bolts or similar aids those two profiles (9) and (10) connect and are on the back of the lancet holder when looking from the edge of the tissue.
  • An advantage of the lancet holder according to the invention lies in the fact that the lancets (2) are held in place by the teeth (8) of the comb (4) and therefore cannot shift laterally during weaving and cannot move on a particular one Move together. As a result, the arrangement of the lancets remains well distributed over the entire width of the tissue.
  • Another advantage of the lancet holder according to the invention lies in the fact that the lancets (2) cannot possibly still tilt on the lath-shaped profile (1) because the width of the grooves between the teeth (8) of the comb (4) is only slightly larger than the thickness e of a lancet (2).
  • An additional advantage of the lancet holder according to the invention lies in the fact that the yarns which have to run closely below or above the lancet holder no longer get caught on protruding parts (such as bolts and the like), on uneven surfaces or sharp edges, because all corners of the profiles (9) and (10) are rounded on the outside because the outer surfaces are smooth and because the heads of the bolts or similar aids that connect the two profiles (9) and (10) have a place take, which can not be reached by the threads (ie on the back of the lancet holder), further because both the back of the lancets (2) and the lath-shaped profile (1) on which these lancets (2) are pushed on the profiles (9) and (10) are enclosed so that these parts cannot be a hindrance to the yarns.
  • protruding parts such as bolts and the like
  • Another advantage of the invention results from the fact that on the one hand the profile (1) is arranged on the comb (4) and that on the other hand the lancets (2) on the short, upright leg (9 ') of the enclosing profile (9) rest.
  • the intended advantage is that the profile (1) experiences additional resistance to bending due to its own weight and the weight of the lancets in a vertical surface and - due to the movement of the fabric in the warp direction - in a horizontal surface. so that no special holder or similar aids have to be provided - which the profile with respect to the loom hold on - to prevent deflections.
