Problems solved by technology

On the other hand, severe operating conditions, especially when used at high ambient temperatures, for example on calenders, lead to different expansions of the materials of the segmented brushes and roller bodies combined in the device
In this case, there are conditions that cause the adjusting rings to shift / misalign with each other during operation, thus causing the individual segment brushes to loosen

Embodiment Construction

[0032] figure 1 shows an apparatus for producing a nonwoven web, for example as it is used in an air-flow process. Such a device has a plurality of working surfaces which are always cleaned by the device according to the invention. figure 1 Only a small part of the plant for the manufacture and processing of nonwoven webs is shown in . A nonwoven web 2 composed of staple fiber segments is produced on the working surface of the deposition belt 3 . To this end, the deposit belt 3 is assigned a forming station through which the fiber segments are deposited onto the deposit belt 3 . The forming station 1 is assigned a suction device 4 on the underside of the deposit belt 3 , which is continuously driven and guided over guide rollers 7 . The surface of the deposit belt 3 forms a working surface 9 which is cleaned by means of the device according to the invention. For this purpose, a cleaning device 8.1 is shown. The cleaning device 8.1 has a roller carrier 11 on which the roll...

Abstract

The disclosure relates to a device for cleaning a functional surface for guiding or treating a material web, preferably a non-woven wed. The device includes 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 various embodiments, 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 rotationally 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 for cleaning a working surface for guiding or processing a web, preferably a nonwoven web / belt, which has a rotatably mounted roller body, A plurality of hollow cylindrical segmental brushes are arranged on the circumferential direction of the roller body, wherein the segmental brushes are connected to each other in a form-locking manner, and the segmental brushes are arranged on two sides of the roller body The adjustment rings in the circumferential direction are tightened. 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 a nonwoven web 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 f...
