  • roller 1 provided with upright slat-like members 2, hereinafter referred to as slats.
  • Roller 1 has a length at least equal to the breadth of a carpet 3 to be made, and is mounted for rotation in a frame (not shown).
  • a swivel shaft 4 Mounted in the same frame is a swivel shaft 4, extending likewise over the entire width of the frame and parallel to roller 1.
  • Shaft 4 carries at least one pair of tongs 6, which it can swivel back and forth over substantially 180. Independently of that movement, shaft 4 can perform a reciprocating lateral movement as indicated by double arrow
  • the yarn is passed through a yarn carrier 9, a passage opening 10 of which is provided with a clamping spring 11, which arrangement is well-known in the art.
  • a cutter 12 arranged between yarn carrier 9 and shaft 4 is a cutter 12, comprising a pair of blades between which the yarn is passed.
  • a yarn clamping and folding device 13 comprising a casing 14 in which a clamping die 16 is slidably arranged (also see FIG. 3 and 4).
  • a bifurcated member or fork 17 which together with casing 14 can be moved up and down as indicated by the double arrow 25.
  • the legs 18 of bifurcated member or fork 17 may consist of sheets extending over the entire length of roller 1, said legs 18 being spaced and dimensioned so that they can move on opposite sides along a slat 2.
  • Die 16 has a recess 34 at its bottom end, formed to slightly enclose the upper edge of a slat when coming into engagement with it.
  • shaft I9 Mounted for reciprocating rotation on the side of yarn clamping and folding device 13 away from shaft 4 is a shaft I9, which is likewise supported in the frame not shown, and like shaft 4 extends the full length of roller 1.
  • Shaft 19 carries a series of fingers 21, one end of which can be moved by shaft 19 into and out of engagement with the upper end of a slat 2.
  • a drum 23, supported in the frame not shown carries a roll of carpet backing 24, which via guide rollers 26 and 27 is guided against the outer circumference of roller l, the arrangement being such that backing 24 follows the intermittent movement of roller 1, at the same rate.
  • adhesive 31 is applied to the backing. by means of a dispenser 29. After leaving guide roller 27, backing 24, provided with pile yarns bonded thereto is rolled up on a drum 28.
  • Tongs 6 are now opened and device 13 is moved downwards (also see FIG. 3) for clamping die 16 to clamp the piece of yarn 33 on the upper edge of slat 32 with its recess 34.
  • the downward movement of device 13 is continued, whereby the legs 18 of fork 17 move on opposite sides along the slat, folding the ends of the piece of yarn 33 about slat 32.
  • clamping die 16 can move relatively to casing 14 against the action ofa helical spring 38.
  • die 16 is retained by slat 32 and clamps the fold zone of the piece of yarn 33 on to slat 32.
  • tongs 6 have been swiveled back into position for gripping a pile yarn 8.
  • Roller I is now rotated to bring the next slat under device 13, and the process is repeated as described.
  • a folded pile yarn has arrived in the position shown in FIG. 1, such as yarn 36 folded about slat 37
  • finger 21 is lowered on to the fold zone of yarn 36 to prevent the latter from being dislodged by leg 18 during its upward movement.
  • roller 1 rotates finger 21 is in a raised position.
  • Backing material 24 is provided with a layer of adhesive 31 when passing dispenser 29. This layer of adhesive is contacted with the fold zones of the pile yarns in the nip formed between the tops of the slats and roller 26. In the path between guide rollers 26 and 27 the adhesive is allowed to set, so that the pile is bonded to the backing, and the ready carpet can be wound on to drum 28 via guide roller 27.
  • FIG. 5-8 show a modified embodiment of the yarn clamping and folding means according to the invention.
  • the folding means comprises a single folding leg 41 movable up and down, and the clamping means is an element 42 extending tangentially to the circumference of roller 1 and movable back and forth in the tangential direction.
  • tongs 6 also perform the function of a clamping means, since the trailing end of the piece of yarn is being retained by tongs 6 during the folding operation.
  • tongs 6 When tongs 6 have moved a piece of yarn 33 over slat 32 theycontinue to hold the yarn while folding leg 41 is lowered to fold the leading end of the yarn (on the left in the drawing) against one side of slat 32. The yarn is then released by tongs 6; folding leg 41 is moved upwards to release slat 32 (FIG. 7); and roller 1 is rotated in increment equal to the distance between two adjacent slats. Element 42 is now moved to the right to maintain yarn 33 clamped on slat 32. Meanwhile tongs 6 have moved a next piece of yarn 39, cut to length, over slat 43(FIG. 7).
  • Folding leg 41 is again moved downwards and presses the overlapping ends of yarn 33 and 39 jointly into the interspace between slats 32 and 43 (FIG. 8). Subsequently folding leg 41 is moved upwards, element 42 is. moved to the left, roller 1 is rotated one increment further, and tongs 6 are swiveled clockwise in position to grip a new piece of yarn, whereafter the cycle is repeated.
  • the method of the present invention can be carried out in apparatus of the first embodiment hereinbefore described, but omitting die 16 and/or finger 21. This possibility depends on the nature of the pile material used, namely, if it has little tendency to become dislodged on a slat once it has been folded around it.
  • Apparatus for use in producing a pile fabric wherein the pile has a predetermined height comprising a roller rotated intermittently and having a plurality of peripherally located, spaced radially extending slats;
