摘要

Apparatus for profiling cylinder pieces by forcing, consisting of at least three juxtaposed rollers (10, 12, 14) arranged with their axes parallel and forming a polygon in their end view, and means for driving one of the rollers, characterized by a circumferential recess (22, 42) in at least one roller that partially defines a closed profiling space adapted to receive and trap a cylinder-shaped part to be machined (26, 36); and further characterized by means for moving the rollers in a mutual approach and distance relationship to vary the volume of the profiler space.
