ABSTRACT:
A cam-support for a knitting machine for the entrainment of the push-rods, respectively of the needles, according to the so-called "three-way" technique, having first, second and third lifting cams intended to entrain the abutment surfaces of the push-rods, respectively of the needles, at several different selection points, so that the needles operate either for shaping, or for picking up or so that they do not operate. The first and second lifting cams are located one beside the other and the third lifting cam is located between them but is separated therefrom by a first channel between the first and third cams and by a second channel between the second and third cams. The channels merge in an empty space between all three cams. A push-rod selected before the arrival of an outer or leading end of one of the first or second cams is entrained by this cam and by the third cam and operates in the knit position, whereas a push-rod selected opposite the empty space is not entrained by the third cam and operates in the tuck position. The three lifting cams may be fixed.
