Problems solved by technology

However, this heating in the axial support causes thermal deformation which can adversely affect the air bearing structure
This known guide roller is therefore energetically very unfavorable for heating the guide sleeve to the desired surface temperature

Embodiment Construction

[0023] figure 1 A first embodiment of an inventive device for carrying out the inventive method is shown. in accordance with figure 1 In the embodiment, the guide roller 1 is shown in cross-sectional view. The guide roller 1 has a rotatably mounted guide sleeve 2 . For this purpose, the guide sleeve 12 is designed as a hollow cylinder. The guide sleeve 2 is held on an axial support 3 which is fastened to a machine frame (not shown here) by means of a bracket end 13 . The support end 13 protrudes beyond the guide sleeve 2 on one end side of the guide roller 1 .

[0024] The axial support 3 extends substantially over the entire length of the guide sleeve 2 , an air bearing 4 being formed between the guide sleeve 2 and the axial support 3 passing through the guide sleeve 2 .

[0025] In this exemplary embodiment, a sliding sleeve 7 is arranged on the circumference of the axial support 3 in order to form the air bearing structure 4 . The sliding sleeve 7 is made of a porous ...

Abstract

The present invention relates to a method and to a device for heating a rotatably mounted guide casing of a guide roller for guiding and heating threads. The guide roller has a guide casing which is held by means of an air mounting on the circumference of a shaft carrier. To heat the guide casing, compressed air is heated outside the guide roller and supplied to the air mounting within the guide roller.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for heating a rotatably mounted guide sleeve of a guide roller / gode roller / godette roller and a method according to claim 6 The device for carrying out the method described in the preamble, wherein the guide rollers are used to guide and heat the filaments. Background technique [0002] It is generally known in the production and further processing of synthetic filaments that one or more filaments are multi-wrapped on the driven godet jacket of the godet, so that the driven godet jacket is based on Wrapping friction is used to transport the filaments. In order to achieve multiple wraps on the godet jacket, the godet is usually equipped with a guide roller having a rotatably mounted guide sleeve for receiving the filament wrap. Such guide rollers are known, for example, from DE 2639439. [0003] This known guide roller has a rotatably supported guide sleeve which is held rotatably...
