Embodiment Construction

[0042] figure 1 A machine 10 for producing knitted fabrics is shown in a schematic schematic diagram, comprising a circular knitting machine 11 and a spinning device 12 . Shown is a needle cylinder 13 of a circular knitting machine 11 and a stitch forming station 15 , which includes a stitch forming element 14 here in the form of a latch needle, on which the stitch forming element 14 can be ejected in order to form a stitch. Furthermore, a control device 16 for the entire machine 10 is shown.

[0043] A spinning device 12 is assigned to the loop formation site 15 , which comprises a drafting device 17 and a twisting device 18 , which is connected to a delivery pipe 19 . The drafting mechanism 17 has a pair of input rollers 20a, 20b, a pair of apron rollers 21a, 21b and a pair of output rollers 22a, 22b. The double apron 23 is guided on the pair of apron rollers 21a, 21b. In each roller pair 20a, b to 22a, b, the lower roller 20b, 21b and 22b is driven respectively. The dri...

Abstract

The invention relates to a machine for producing knitted fabric, comprising a plurality of stitch-forming elements and at least one stitch-forming location (15, 15.1, 15.2, 15.3), with which is associated a spinning device (12, 12.1, 12.2, 12.3) which produces a fiber composite (FB) or a yarn from a roving (VG) and supplies the same to the stitch-forming elements (14), wherein each spinning device (12, 12.1, 12.2, 12.3) is provided with separate drive devices (30, 31, 30.1, 31.1, 30.2, 31.2, 30.3, 31.3) which can be controlled in such a manner that a fiber composite (FB) or a yarn of variable thickness can be produced by each spinning device (12, 12.1, 12.2, 12.3) from the roving (VG) and be fed to the stitch-forming elements (14).

Description

technical field [0001] The invention relates to a machine for producing knitted fabrics, comprising a plurality of loop-forming elements and at least one loop-forming station, which is equipped with a spinning device for producing fiber strands or strands from rovings. yarn and supply it to a plurality of coil forming elements respectively. The invention also relates to a method for producing a knitted fabric and a knitted fabric produced according to said method. Background technique [0002] Such knitting machines, especially circular knitting machines, have been known for some time in the past, in which the needles are supplied with fiber strands (Faserverband) or yarn, which fiber strands or yarns are passed directly through the spinning machine assigned to the knitting system of the knitting machine. The yarn device is made of roving. WO 2004 / 079068 A2 describes a knitting machine in which a drafting mechanism draws a roving into fiber strands of a desired fineness an...
