Positive needle control

Positive guiding of needles through a cam system can be achieved on circular machines knitting plain unpatterned fabrics. In cam systems on jacquard machines, needle butts have to be switched to a choice of cam-tracks. At this point they cannot be under positive control so the cam-track is open. To reduce the chance of the unguided needle butt moving to a wrong position, needle movement is slowed down by using one or more of the following methods:

  • Reducing the machine speed.
  • Using friction needles, which also cause wear.
  • Using flatter cam angles, which cause holes in the fabric.

With positive needle guidance, the needle has an additional control butt that is attached to a jack. This slides in a slot in the tail of the needle without causing unnecessary movement to the needle.
