Definitions

  • This invention relates to a method of producing ribbed two-machine warp goods on a frame having only one row of needles.
  • Ribbed warp goods were hitherto made exclusively on frames having two rows of needles, and the invention makes it possible for the first time to produce such goods, especially transversely ribbed goods, on a machine having only one row of needles.
  • a ground fabric is lapped first with the upper machine, for instance in the form of a simple tricot lap, under 1 over 1 and back, while the lower machine, in order to form ribs, places the threads under the needles, e. g. under 2 and back, so that during these operations the lower machine is racked alternately once in the same direction as the upper machine and then again in a direction opposite to the latter.
  • Fig. 3 is a diagrammatic view showing parts of the upper and lower machines in producing the goods of Fig. 2, and Fig. 4 is a similar view for producing the goods of Fig. 1.
  • the upper machine or row of guide needles 0 produces with its thread I the ground fabric, such as a plain tricot (under 1 over 1 and back) while the lower machine it, in order to form ribs with its threads 2 operates under the needles, such as under 2 and back.
  • the lower machine with the threads 2 will be racked once in the same direction as the upper machine with its threads I and then again in a direction opposite to the latter.
  • the change in the direction of motion of the lower machine relative to that of the upper machine may be effected in any suitable way, by omitting for example to laterally rack the lower machine with its threads 2 for an odd number of courses.
  • the lapping diagram according to Fig. 1 shows how the lower machine or row of guide needles is racked in the six courses a in the same direction as the upper machine.
  • the lower machine In the course b the lower machine is not racked laterally at all and in the three following courses 0 the lower machine is racked in a direction opposite to that of the upper machine.
  • the next course b lateral racking of the lower machine is omitted, so that the lower machine in the connecting six courses a of the next repeat may be racked again in the same manner as the upper machine.
  • Racking which takes place, for the purpose of forming ribs, alternately in the direction of the upper machine and then again opposite to the latter, involves alternate throwing up of the goods towards the rear and front side.
  • the reasons are chiefly found in the fact that only the threads 2 of the lower machine are placed under the needles to form ribs. In this way these threads 2 are not stitched on to one side of the goods so to speak, as is the case with plain cord with lining, but the threads 2, as clearly indicated in Fig. 2, interlace in the ground fabric.
  • the lower lapping machine can also lap over the needles at points in addition to lapping under them except at points where the lower machine has to form ribs.
  • a method of producing transversely ribbed warp fabric by means of two lapping machines on a warp loom having only one row of needles comprising lapping a ground fabric with the upper machine and carrying out underlaying operations with the lower machine to form ribs, the
  • a method according to claim 1 in which the racking of the lower machine is omitted for an odd number of courses and then racked in the opposite direction to the upper lapping machine. 3. A method according to claim 1, in which the underlaying operations of the lower machine are produced on at least two needles.
