  • CT A web is transported on a table crossed by a needle
  • Appl' 84062 holder bar in which a row of needles is mounted for movement between retracted and advanced positions.
  • Foreign A li ti P i it D t Selected needles of the row are locked in the advanced position by control means of the Jacquard Oct. 24, 1969 Germany ..P 19 53 494.2 machine type w e the table with the web i moved toward the needles, the selected locked needles [52] U.S. Cl. ..28/4 R, 28/722 R penetrate the web forming depressed portions in the Cl.
  • the present invention relates to apparatus for forming a relief pattern, or colored pattern, on a web, preferably a web consisting of a fibrous material.
  • Another object of the invention is to place needles selectively, and under the control of program control means, in selectedv positions in which they penetrate into a fibrous web, while other needles are not selected, and do not penetrate into the web.
  • the objects of the invention are obtained in accordance with the invention by mounting needles in a needle holder for longitudinal movement, and to lock selected needles so that, the same can penetrate the web, while non-selected needles are pushed back by the web to inoperative positions, and do not penetrate the web.
  • An apparatus constructed in this manner is extremely simple, and in order to obtain a pattern on-a web, it is only necessary to determine the desired pattern, and to set program control means accordingly, so that the program control means select the locked needles in accordance with the pattern.
  • a card with punched holes can be used for this purpose with a Jacquard machine.
  • the record carrier on which the program is recorded is stepwise sensed, and the determined control impulses automatically carried out by the control means, so that the locking means either lock or release the respective needles.
  • the locking means either lock or release the respective needles.
  • the respective needle is locked, and cannot be displaced by the web moving toward the needle, so that the needle penetrates into the web.
  • the web moves away from the needle holder with the needles, the web is stripped off the needles. Those needles which are not locked are pushed by other portions of the web to an inoperative position completely located in the needle holder means.
  • the needles produce in successive operational cycles, stitches of different density in accordance with the pattern recorded as a program. If in one portion of the web, a number of needles produce dense stitches, the fibers or threads of a the web are depressed to a substantial degree, and are compressed so that the respective surfaceportion of the web is depressed and lower than the other surface portions in which due to unlocking of the needles, the needles were unable to penetrate the fabric by densely arranged stitches. In this manner, a relief pattern is obtained, since the portions of the web with dense stitches are thinner than portions of the web where the stitching is less dense.
  • the web consists of two layers of different colors which are superimposed and then together stitched in accordance with the invention, a colored pattern is obtained on the side of the web remote from the needles. Due to the stitching by the needles, the rear face of one layer is compressed in certain pattern determined portions, and the fibers are pushed from this layer into and through the other layer and form a pattern on the front face of the other layer. Dependent on the density of the stitching by the needles, the original color of the front layer is changed by fibers of the rear layer. Where web portions in the original color of the front layers are desired, the web is not stitched in the respective region, or only stitched by a few needles which are locked in accordance with the invention.
  • the final pattern is influenced by the color, layer, thickness, density of the stitching, and by the material of the web. If in the initial material, a comparatively large layer is penetrated by the needles, a clear relief structure is obtained if stitching of different density is applied to different portions of the pattern.
  • the desired pattern requires comparatively large web portions which are not stitched, it is advisable to place a powder of a thermoplastic synthetic bonding agent between the layers of the web, and to heat the web after stitching so that the layers are not only connected by the stitching, but also by the bonding agent, and adhesively adhere to each other.
  • a powder of a thermoplastic synthetic bonding agent between the layers of the web, and to heat the web after stitching so that the layers are not only connected by the stitching, but also by the bonding agent, and adhesively adhere to each other.
  • it is advantageous to blow hot air into the fibrous web since in this manner, the bonding agent is quickly heated.
  • the apparatus of the invention not only permits the stitching of the web to be of different density, in accordance with the pattern, but it is also possible to permit the needles to penetrate to different depths of the web.
  • several rows of needles are mounted in the needle holders, which are of different length, or perform strokes of different length relative to the web.
  • each needle with several locking means which in the operative locking positions thereof partly or totally prevent the displacement of the needles. For example, if a first locking means is placed in the locking position, the needle is supported during the working stroke, and will penetrate the web. However, if the first locking means unlocks the needle, but another locking means for the same needle is moved to the locking position, during the following stroke of the machine, the needle can be pushed into the holder for a short distance, until abutting the second locking means so that the needle penetrates into the fabric for a shorter distance than when locked by the first locking means.
  • the first and second locking means can be actuated by the program control means in accordance with the program to produce deeper or less deep penetration of needles into the fabric, depending on the actuation of the first or second locking means.
  • different needles have different hooks which are of different size, or provided on the needle in a different number.
  • the hooks displace fibers or thread portions of the web when penetrating into the same.
  • Difierent hooks displace different amounts of fibers.
  • the apparatus of the invention permits the making of a very wide range of different patterns, which may be combined.
  • the termination, or the variation, of the program can be quickly and easily carried out by using a different card with differently punched holes in the pattern control means.
  • An embodiment of the invention comprises supporting means, preferably including a table for a fibrous web; transporting means, preferably secured to the supporting means for transporting the web stepwise in one direction; a needle holder for guiding a plurality of needles between an inoperative position located in the needle holder, and an operative position projecting from the same toward the web; a plurality of locking means, preferably including locking latches, cooperating with the needles, respectively, and having an inoperative position and a locking position for locking the respective needle in the operative position; and control means for actuating selected locking means to move to the locking position so that the respective needles are locked after a step of the web.
  • the locked needles penetrate in the operative position into the web for depressing the penetrated portions of the web, while non-selected locking means permit other portions of the web to push the respective needles to the inoperative position so that other portions of the web are not depressed.
