Improved needle selector in circular knitting machine for manufacturing mens' socks or the like

摘要

The improved needle selector (1) in a circular knitting machine has an oscillating arm (7) which is arranged on the same plane as a needle (2) and has a top (7a) that abuts from below against a sub-needle (5). The arm (7) has, at its base, two heels (8,10) at different levels for engaging a lifting cam profile (9). The arm (7) is selectively movable to a lateral position, in which the heels (8,10) at different levels do not interfere with the lifting cam profile (9), or to two positions in which one of the two heels (8,10) interferes with the profile (9), a low position, a casting-off position, and a holding position of the needle (2) being obtained respectively in these positions of the arm (7).
