Embodiment Construction

[0039] FIG. 1 schematically shows the principle of a prior art circular knitting machine equipped with a drawing system in order to be able to manufacture knitwear directly from rovings. The circular knitting machine is denoted as a whole by the reference numeral 1 and has a needle cylinder 3 on which, for example, 48 or 96 knitting points with movable needles 4 , in particular latch needles, are arranged. The needles 4 directly process the roving Y which is supplied to the knitting point 2, for example as a drafted sliver from a tank or as a flyer roving from a flyer bobbin 5 which can be mounted on the circular knitting machine 1 in the bobbin holder. In this case, the knitting point 2 is considered to be the point at which the fiber strip Y is conveyed to the knitting needles 4 arranged on the needle cylinder 3 .

[0040] The circular knitting machine 1 is preceded by a drawing system 6 in which the roving Y is drawn to a desired fineness into a fiber sliver. Only a singl...

Abstract

The invention relates to a knitting machine (21) for processing rovings (Y) comprising a number of knitted points (22), the needles (24) of which are each fed rovings (Y) pretreated accordingly in a roving treatment device (26) in order to produce knitted fabrics therefrom. Upstream of the knitted points (22), roving treatment devices (26) are provided, which each comprise an unraveling device (30) for unraveling the rovings (Y) into individual fibers (F) and a friction spinning device (40) for processing the individual fibers (F) into a transport-stable yarn (T) having the desired fineness. In addition, a method for processing rovings (Y) into a knitted fabric on a knitting machine (21) is described.

Description

technical field [0001] The invention relates to a knitting machine for processing rovings according to the preamble of claim 1 . The invention also relates to a method for producing knitwear from rovings according to the preamble of the independent method claim. Background technique [0002] It has been proposed in various ways in the past that the knitwear is produced directly from staple fibers or rovings. Through the knitting process of a substantially non-rotating fiber sliver with approximately parallel oriented fibers, the resulting knitwear has a very "soft hand" and a very high wearing comfort. Furthermore, the knitwear can be produced very cost-effectively, since the conventional intermediate steps of yarn production, namely yarn formation, winding and, if necessary, rewinding, are omitted. [0003] For example in US-A-3,877,254 it is proposed to feed staple fibers to the needles of a knitting machine. The device described there is illustrated by way of example o...
