Abstract:
The invention relates to a method for producing a circular cylindrical body (10) comprising a workable mass, having at least one helical internal cavity extending in the interior of the body. The body (10) is initially produced with a straight internal recess, for example by means of extrusion. Afterwards the body is cut to a defined length. The body (10) that has been cut to length is then subjected to a rolling process by means of a friction surface arrangement (23) while being supported over the entire length thereof on a support means (16). The rolling process takes place in multiple steps, wherein a rolling movement using a first axis of rotation (25) is performed in a first step, and a rolling movement using a second axis of rotation (26) that is different from the first axis of rotation is used in a second step. The invention also relates to an apparatus for performing the method.
