Definitions

  • Knitting machines have one or several warp beam sections, each warp beam section of which can be defined as a row of cylindrical metal spools on which warp yarns are wound.
  • the warp yarns are drawn from the beams to guide bars and then to the needle bars where the fabric is knitted.
  • the knitted fabric which is typically 168 inches in width, then feeds from the needle bars to the takeup roll or rolls where the knitted fabric is accumulated in roll form.
  • Warp-knitting machines usually have two to four warp beam sections.
  • the yarn from each warp beam section has a tension letoff control that governs the tension or feed rate of warp yarn passing over the guide bar to the needle bar.
  • FIG. 2 is an exploded perspective view of the pulse generator and the automatic tension letoff control arm of each warp beam section on which the pulse generator is mounted;
  • FIG. 7 is a vertical section view through the variable diameter pulley, taken along the line 7-7 of FIG.6c.
  • the COURSES PER REVOLUTION switch 37 will be placed in the 12 position.
  • the AND-gate A62 is high (has a one) on its B-input and is high (has a forty) on its A-input, then the output of AND-gate A62 will go high.
  • the high output on AND-gate A02 will feed to the reset driver 36 and reset flip-flop s FF1, FF2 and FF3 so that the Q-outputs will go low and the Q-output will go high.
