Problems solved by technology

Increasing the size of this barrel is a step backward in the technical way and makes it impossible in any case for structural reasons and lack of space
Also, assembling the draw frames as a group means that servicing them is difficult

Embodiment Construction

[0033]For greater clarity, the same reference numerals denote the same components in the figures.

[0034] figure 1 Shown is an overview of the important components of a circular knitting machine, generally denoted by reference numeral 1, which makes knitted fabric directly from the roving. The circular knitting machine 1 has a needle cylinder 2 on which, for example, 48 or 96 knitting needles 3 , in particular latch needles, are movably arranged. The needles 3 directly process the roving provided by the drawing frame sliver from the can 5 or the roving yarn from the roving bobbin, which is placed on the bobbins of the circular knitting machine. The roving L is drawn in the drafting unit 6 and supplied to the knitting needles 3 to form the fiber sliver into a knitted fabric either directly or via an intermediate twisting device 4 The stretched fiber slivers have false twist. exist figure 1 The drafting unit shown schematically in figure 1 In particular a three-cylindrical...

Abstract

The invention relates to a drafting unit (6) for a knitting machine for forming a roving into a fiber sliver, which has a double apron (8) guided by apron rollers (81, 82) and can be drawn by Motor driven exit pressure roller pair (9). Both the pair of apron rollers for the double apron (8) and the pair of outlet pressure rollers (9) have respectively driven lower cylinders (82, 92) with shafts, one end of which is connected to the base (60) And protrude freely from the base. The lower cylinders (82, 92) are driven by electric motors (62, 63).

Description

technical field [0001] The invention relates to a drafting unit for such a knitting machine. Background technique [0002] In the past, various methods of manufacturing knitted fabrics directly from staple fibers or rovings have been proposed. Knitted fabric that weaves a sliver of roughly untwisted fiber with roughly parallel fibers is very soft and very comfortable to wear. Moreover, since the intermediate stages of traditional spinning - the formation of the yarn, its winding onto the spool and possible rewinding - are omitted, the production of the knitted fabric can be very economical. The sliver of untwisted fibers also has a certain degree of longitudinal elasticity, so it is easier to resist changes in direction of the yarn guiding the knitting machine and the yarn does not break too often. [0003] For example, document US-A-3,877,254 proposes to transfer staple fibers to the needles of a knitting machine. In this case a circular knitting machine was taken as the...
