Abstract
A needle actuation device comprises a cam box facing a needle holder and supporting at least one lowering cam whose profile is inclined with respect to the direction of the motion of the needle holder with respect to the cam box. The profile of the lowering cam engageable by a needle or needle pusher heel, protruding from the needle holder. The lowering cam is movable along an adjustment direction in which at least one component is parallel to the direction of the sliding of the needles in the needle holder, to vary length of knitting loops, and rotatable to vary inclination of the profile with respect to the motion direction. Adjusters are provided to vary inclination of the profile of the lowering cam both correlated to the loop length variation and independently of the loop length variation.
