Description

The invention relates to a device for cleaning a convex surface of a godet for transporting and tempering a synthetic thread according to the features of claim 1.

In the production of synthetic threads using godets, it can be seen that after a short time, in particular after three days, a grooved deposit can form on the godet surface.

This is caused by monomers and/or preparation oils that lead to groove-shaped deposits on the godet surface.

The groove deposits are particularly negative in the case of heating godets, since these groove deposits impair the heat transfer and thread qualities.

Currently, the removal of the groove deposit from the surface of the godet sleeve is done by first manually applying a cleaning agent to the soiled godet surface by an operator.

The cleaning agents can be applied using cloths. In order to improve the effect of the cleaning agent, however, the surface of the godet jacket is often additionally wrapped with cloths in order to improve the effect over time.

After a predetermined exposure time of the cleaning agent, the cloths are put down and the godet surface is manually cleaned of the cleaning agent and other residues using special cleaning cloths.

Cleaning is carried out until the cleaning cloths are no longer visibly soiled and the groove deposits are no longer detectable.

This should always take place with stationary godets. However, from time to time it can happen that the operator, for reasons of time, carries out the cleaning on a godet, which rotates itself via its drive.

However, operating the galette with electricity during this cleaning process can lead to accidents at work and is also not permitted by the manufacturer because of this risk.

The object of the invention is therefore to provide a device for cleaning the convex surface of a godet casing, which can also be used when the godet casing is in operation and provides the necessary occupational safety so that no more accidents can occur at work.
