Problems solved by technology
However, the solution described in DE 1 883 936 U capable of lifting the cleaning roller off the surface of the roller to be cleaned does not contain any implication that the cleaning roller can be adapted to the changing diameter ratio of the roller in the case of regrinding the roller , so that the device is not able to ensure a uniform pressure distribution on the surface of the roller to be cleaned

Embodiment Construction
[0021] figure 1 A side view of an apparatus 1 according to the invention for processing fibrous material F is shown. The device 1 comprises rollers 4a, 4b which are frictionally driven by a roller 17 connected to a drive not shown here. In the present example, the roller 17 is the output roller of the drafting device, on which the pressure roller 4a rests. The pressure roller 4a has, for example, a rubber coating on its peripheral surface 3a. Arranged downstream of the delivery roller 17 is a compacting roller 4 b which is frictionally driven, for example, by the delivery roller 17 . Typically, the compacting roller 4b has a metal surface 3b on which the fibrous material output from the drafting device is compacted. The compacted fiber material F is then transported via the clamping station K1 to twist generating components not shown here. The clamping station K1 is formed by an anti-twist roller 18 resting on the peripheral surface 3b of the compacting roller 4b.

A device (1) is provided for cleaning roller surfaces (3a, 3b) of rollers (4a, 4b) that are arranged one behind the other at a radial distance (b) from one another for processing fiber material (F) on a textile machine. A clearer roller is received in a guide (7) of a clearer roller holder (2), wherein the guide is acted on by a spring element (6), and the clearer roller is pressed via a pressing force (AK) against the roller surfaces of the adjacent rollers. In order that by swiveling a top roller support arm (12) upwards, the clearer roller is lifted off the roller surfaces to be cleaned and is able to adapt to different diameter ratios (Db / Da) of the rollers so that a consistent pressure distribution on the roller surfaces to be cleaned is ensured, the longitudinal direction (L) of the guide runs at a distance (a) to a plane (E) in which lie the two axes of the rollers that are arranged at a radial distance (b) from one another.
Description
technical field [0001] The invention relates to an apparatus for cleaning the roller surface of rollers arranged one behind the other at a radial distance from each other for processing fibrous material on a textile machine, the apparatus comprising a cleaning roller received in a guide of a cleaning roller holder Rollers, wherein said guides are acted upon by spring elements so that the cleaning roller is pressed against the roller surface of the adjacent roller via a pressing force. Background technique [0002] A device of this type is described, for example, in US 2,730,770. Here, the device is embodied as a multi-cylinder drafting device for drafting fiber material. The multi-cylinder drafting unit consists of three roller pairs arranged one behind the other and forming a pre-drafting zone and a main drafting zone. In the main drafting area, a lower apron and an upper apron are arranged for guiding the fiber material, wherein the lower apron and the upper apron each r...
