ABSTRACT:
A sinkerless knitting machine with latch needles, comprising a needle holder with a plurality of slots on one face, each slot accommodating a needle. Knitting retainers are provided, each with a body composed of at least two side-by-side interconnected laminar elements. At least two laminar elements of each knitting retainer are arranged in a same or in two contiguous slots of the needle holder. At least one of the laminar elements composing a knitting retainer has a retention portion defining a stop shoulder for the knitting. Each knitting retainer can move on command from a first position, in which it does not interfere with the knitting being formed, to a second position, in which it is inserted, with the retention portion, between two contiguous needles, in a region which faces the knitting forming plane, in order to retain the portion of knitting that lies between two contiguous needles.
