Definitions

  • This invention relates to improvement in loopers for use with tufting machines for manufacturing pile carpets, tufted carpet in particular.
  • a plurality of needles arranged in parallel so as to move up and down are inserted from the back of the ground fabric.
  • the pile yarns in the needles are then engaged . by a plurality of the loopers provided at the right side of the ground fabric.
  • the piles are left projecting from the surface of the ground fabric. Repetition of this operation in succession forms a tufted carpet with a tuft of loop piles or cut piles formed by cutting the loop piles with a knife.
  • a conventional looper for the tufting machines has a pile yarn stopper 1', the lower edge 2' of which extends straight to the frontmost end, and a plate spring 3' butting with the lower edge of the pile yarn stopper.
  • pile yarns are pulled out of the stopper 1' of the looper to make a carpet of loop piles.
  • a knife goes up to cut off the loops to make a carpet with cut piles.
  • An object of the present invention is to provide an improved looper for tufting machines which obviates the abovementioned shortcomings.
  • the pile yarns 13 in loop form are prevented from being pulled out by the plate spring 6 butting against the lower edge of the stopper 1 and remain in the looper A and move backwardly as the ground fabric 14 moves.
  • the knife 11 goes up, the pile yarns are cut by the contact of the looper with the knife 11, so that cut piles are formed.
  • the pile yarns 13 in loop form stopped with tension in the stopper 1 of the looper are abraded by the stopper as the looper moves forward and backward, if it is of a conventional type.
  • the stopper 1 is made to an inverted U-shape at 3 by denting at the rear part as shown in Fig. 1 to Fig. 4.
  • the pile yarns 13 in loop form move rearwardly as shown in Fig. 1 and are caught in the inverted U-shape part 3.
  • the tension is released. Accordingly, the inverted U-shaped part 3 of the stopper 1 does not come into tight contact with the pile yarn 13 even when the looper moves forward and backward, so that the pile yarn 13 will not be abraded or damaged.
  • the inverted U-shape part 3 at the rear part of the stopper 1 makes it possible to attach a tip 10 made of cemented carbide so that its lower edge will not catch the pile yarn 13. Therefore, pile yarns are not caught by the tip when the looper moves forward and backward, and the looper can be used to the expiry of the life of the tip 10.
  • the looper according to the present invention therefore, is durable for 250,000 to 300,000 meters of pile yarn while the conventional type is for about 80,000 meters only.
  • the looper of the present invention can also be used for another 250,000 to 300,000 meters simply by grinding the tip 10.
  • the brazed part does not affect the pile yarn 13 directly by forward backward motion of the looper even if the brazing is peeled off.
  • the inverted U-shaped part 3 is provided at the stopper 1 of the looper, the distance between the ground fabric 14 and the piles becomes shorter by the dent even though the distance between the fabric and the looper is the same. Accordingly, the pile length for cut piles can be shorter, which makes smaller the difference from the length of loop piles.
  • the above is not only true for cut loop loopers but also for plain cut loop loopers in which the plate spring 6 moves forward and backward for switching between cut piles and loop piles as shown in Fig. 4.
