Abstract: 10,796. Duval, P. E., and Sabonadier, P. A. J. May 10. Pile fabrics carpets; yarns, warping; chenille looms, pile-forming in. -In the manufacture of Turkey carpets and tapestry hangings similar to those known as Gobelin or Beauvais, each transverse row of pile fibres g, Fig. 13, is, previous to weaving, prepared in the form of a strip resembling chenille but held together by gummed paper bands w. The pile design is prepared as usual on squared paper, and is mounted on a board a, Fig, 3, which may be raised and lowered by mechanism d to bring the transverse line to be read to the level of a straight-edge e. As the first line is read, spools of thread g corresponding to the points of the line are placed in order on spindles on a table b. The threads are drawn through a comb h, and wound in their proper positions on a roller k by means of a crank l. If the depth of pile is 2 centimetres, each pile fibre is 4 centimetres, and sufficient length for forming pile strips for one hundred carpets, or 4 metres, may be wound. The threads are cut, and the spools are then removed and replaced by the spools corresponding to the second line of the design. The new threads are attached to those on the roller, and the operation is repeated line by line until the roller k has received all the pile thread necessary for one hundred similar carpets. The roller k is removed, and mounted at the extremity of the apparatus shown in Fig. 6. The tbreads g are guided by spreaders o and pass through a comb p, after which they are taken between two sheets of paper q, r, which are unwound from rollers above and below. A gumming-arrangement s deposits a layer of gum at intervals of 4 centimetres on the lower surface of the upper sheet. The compound sheet y then passes between compressing-rollers, driven by chain and spur gearing, and heated internally by rows of gas jets to ensure the adhesion of the paper sheets, and is wound on a belt-driven roller. The sheet is then unwound, and cut by hand into lengths of 4 metres, that is, a length for each row of pile fibres on the pattern. The sheets are then placed in order one above the other upon the table of a cutting-machine, and are cut into a hundred small similar heaps each containing all the pile strips for one carpet. The strips are then freed from most of the paper by being fixed between two pronged jawa which tear away the ungummed parts, or by other means. Each strip is then held by hand or by a clamp 7, Fig. 16, above the warp threads c in the loom, and the loose ends of the pile thread g are pressed through the warp threads and against a previouslyinserted weft t, Fig. 24, by a metallic brush 8. Another weft t<1> is then inserted, and is beaten up by the reed 9. The ends of pile thread g are then pressed upwards through the warp by a second brush 10, and a weft t' is inserted and beaten up. The pile strip is released, and the operation is repeated until all the strips are used. When the carpet or other fabric is completed, the strips of paper ware removed by means of a teasel.
