Stitch control device in flat knitting machine

A loop length controller, for a flat knitting machine, adapted to set a loop length of a knitting fabric by raising or lowering a stitch cam attached to a carriage that is to slide on a needle bed for slidably operating knitting needles forward and backward, said loop length controller comprising:

• a raising and lowering device for raising and lowering the stitch cam, said raising and lowering device including
• (i) a driving motor, and
• (ii) a converting mechanism for converting rotational movement of said driving motor into ascent and descent of the stitch cam, said converting mechanism being constructed and arranged such that an amount the stitch cam ascends or descends with respect to rotational movement of said driving motor for a side corresponding to a larger drawing-in amount of the knitting needles, for producing loops of longer length, is different than an amount the stitch cam ascends or descends with respect to rotational movement of said driving motor for a side corresponding to a smaller drawing-in amount of the knitting needles, for producing loops of shorter length.
