ABSTRACT:
For the profile kneading of workpiece in strand from (semiproducts) which are transported along a central axis into a working station (profile kneading machine) at least two dies situated opposite one another in pairs for working on the surface of the workpiece are driven by rams at their extremity remote from the axis; the rams are driven radially toward the axis by rolls (cylinders, balls) moving on a circular path relative to outer guiding surfaces of the rams; at the same time at least two pairs of dies, whose radial driving directions are displaced from one another by a given angle (90.degree.), are driven successively by the rolls in a radial direction by means of the guiding surfaces of the rams; the edge length of the dies in each working step is greater than the targeted edge length of the workpiece (semiproduct) that is to be worked.
