摘要
The present invention relates to an open-type knitting machine for producing variable width open blanket with a fabric take-up and / or unwind assembly comprising: a foundation (3); a knitting head (4) mounted on the foundation (4) and comprising: at least one needle containment element (5) having at least a plurality of needles (6, 7) disposed about a central geometric axis (xx). a first active needle (6a, 7a) and a last active needle (6b, 7b, 6b ', 7b') of the plurality delimit between them a dead zone (11) of the needle-free needle containment element (5) and / or without active needles, and an operating zone (10) shaped as a circle arc and provided with active needles. The control means are operatively connected to the active needles for the purpose of selectively acting on these active needles to produce a partially tubular knitted fabric. a collection and / or unwinding assembly (2) for knitted fabric (t) under production is arranged downstream of the knit head (4) with respect to a feed direction of said knitted fabric (t) under and is integral with the needle containment element (5) during the production of knitted fabric (t). The circular machine (1) further comprises devices (34) for adjusting the angular position of the take-up and / or unwind assembly (2) relative to the dead zone (11) of the needle containment element (5) about the geometric axis. central (xx).
