Abstract

The invention relates to a device for cleaning a functional surface for guiding or treating a material web, preferably a non-woven web. The device comprises a pivotably mounted roller body, a plurality of hollow cylindrical brush segments being disposed on the circumference thereof and positively connected to each other and tensioned between two adjusting rings disposed at the circumference of the roller body. According to the invention, in order to ensure secure tensioning of the brush segments regardless of the surrounding conditions, at least one of the adjusting rings is axially flexibly retained at the circumference of the roller body and a compression ring rotational fixed to the flexible adjusting rings is axially tensioned against the roller body by means of at least one spring element, such that an axial force acting on the brush segments is generated.

Description

technical field

[0001] The invention relates to a device according to the preamble of claim 1 for cleaning a working surface for guiding or handling a web, preferably a nonwoven web / belt. Background technique

[0002] In the manufacture of nonwoven webs containing fibers, especially in the air-laid process (Airlaid-Prozess), in which a certain number of fiber segments are formed into nonwoven webs on a deposit belt, the More or less difficult-to-handle dirt occurs on the working surface for guiding or processing the nonwoven web due to the adhesion of unbonded short fibers or dust particles. Such working surfaces, which may be formed on laying belts, conveyor belts, calenders or individual guide rolls, must therefore be cleaned continuously or intermittently in order to ensure product quality. It is generally known to use rotatable segmented brushes for cleaning the work. Such a device is known, for example, from DE 19726970 A1.

[0003] In this known device for cleaning ...
