    3.3.3 How to adjust needle and feed motion If the machine is set to produce the longest stitch (see chart), the feed motion stops when the point of the needle is placed ca. 4 mm within the cup edge before penetrating the fabric. Transportation is beginning when the needle leaves the material and the needle tip with the nose is in line.

  • Page 21: Looper

    Looper The looper motion is determined by the stroke of the looper eccentric (F) Fig. 2) and by the crank distance. The looper motion must start and end at the same time as the needle bar motion. The lateral looper movement is determined by the shape of the control cam and must be in accordance with the needle motion.
