In the case of a slightly profiled roller, it is advisable to measure the circumference of the coating in the cross-sectional plane to be roughly equal to or slightly larger than the development of the roller circumference. In this case the lifting of the coating from the surface of the roller is caused by its peripheral tension.

The self-cleaning effect of the rollers or of the coating occurs not only when the rollers a _{5 are driven} by the clay strand itself, but also when the rollers, as is known per se, are moved at a relative speed by their own drive.

The invention is explained in more detail below, namely shows.
