OPEN-TYPE CIRCULAR KNITTING MACHINE FOR THE OPEN AND WIDTH-VARIABLE WEB PRODUCTION WITH A KNITTED FABRIC TAKE-DOWN AND/OR COLLECTING ASSEMBLY

摘要

The present invention relates to an open-type knitting machine for the open and width-variable web production with a fabric take-down and/or collecting assembly, comprising: a basement (3); a knitting head (4) mounted onto the basement (4) and comprising: at least a needle-holding element (5) having at least a plurality of needles (6, 7) arranged around a central axis (X-X). 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-holding element (5) without needles and/or without active needles, and an operating zone (10) shaped as an arc of circle and provided with active needles. Control means are operatively connected to the active needles so as to selectively actuate these active needles in order to produce a partially tubular knitted fabric. A take-down and/or collecting assembly (2) for the knitted fabric (T) under production is arranged downstream from the knitting head (4) with respect to a feeding direction of said knitted fabric (T) under production, and it is integral with the needle- holding element (5) during the production of the knitted fabric (T). The circular machine (1) further comprises devices (34) for adjusting the angular position of the take-down and/or collecting assembly (2) with respect to the dead zone (11) of the needle-holding element (5) around the central axis (X-X).
