Abstract

In an apparatus for rolling threads or similar profiles by means of two rolling tools (4,5) which rotate in the same direction and the spacing (a) of which relative to one another can be altered, the rolling tools (4,5) are arranged on corresponding displaceable guides (10) for the purpose of altering their spacing (a) relative to one another. Both rolling tools (4,5) or their guides (10) are connected via a lever arrangement (20) to a central lever (21) which can be rotated about an axis (A) by a drive (32). <IMAGE>
