Embodiment Construction

[0019] The invention will be described in more detail on the basis of an embodiment shown in the figures.

[0020] figure 1 Illustrated is part of a drafting unit having two cleaning rollers 1 each fitted between two upper roller bearing weight arms 2, 3 and positioned on each two of the preceding pair of drafting rollers and two other cleaning rollers 4, 5 on the upper rollers of the outer front pair of drafting rollers beside the outer upper roller bearing weight arm 2. The cleaning roller 1 cooperates with the upper roller of every two tracks, while the cleaning rollers 4, 5 only cooperate with the upper roller of each track during the spinning operation. All pairs of drafting rollers and their arrangement are not shown for reasons of simplicity. The upper roller supports the weighted arms 2, 3 with a bearing element 6, and the cleaning rollers 1, 4, 5 are arranged laterally of the bearing element 6, respectively. The other bearing elements for the cleaning roller and th...

Abstract

The invention relates to a drafting arrangement for spinning groups, comprising at least one upper roller carrier and weighting arm which is held by a machine frame and has clearer rollers which can be rotated about an axis and displaced transversally in relation to the rotating axis thereof in a guide of a bearing element. Said clearer rollers are mounted on the upper roller carrier and weighting arm in such a way that they rest on the respectively associated upper roller. At least one end of a clearer roller (1, 4, 5) axis embodied as a hollow bearing pin is designed with a holding device which grips behind the connecting link guide of the bearing element (6). Clearer rollers (4, 5) overlapping one track and clearer rollers (1) overlapping two tracks can alternatively be suspended in the upper roller carrier and weighting arms, in the same bearing element, without making changes to the bearing element (6). The inventive embodiment of clearer rollers (1, 4, 5) and bearing elements (6) enables a simple, easy and rapid assembly and disassembly of said clearer rollers (1, 4, 5).

Description

technical field [0001] The invention relates to a drafting device for a spinning machine according to claim 1 . Background technique [0002] The fiber material to be spun is usually introduced into the spinning unit in the form of rovings, before which the rovings are drafted. Use a drafting device for this. Unwanted fiber waste winds up on the rollers or cylinders of the drafting unit during the spinning operation. If this fiber material adhering to the rolls becomes detached from the rolls again and gets trapped in the roving guides, also called tracks, the rovings can acquire unwanted knots or slubs. This can lead to unacceptable yarn defects. It is known to use cleaning rolls to remove fiber waste from the drafting unit rolls again. The cleaning rollers are frictionally driven by the working rollers of the drafting unit and have a cleaning layer. The cleaning layer is swept intermittently or continuously. [0003] CH 402 690 of the same type describes a drafting d...
