Abstract

The ejection device (1), particularly for a cold re-shaping unit, has a thruster (4) activated by an ejection lever (3) connected to a rotating drive shaft (2). On the drive shaft a curve (5) is provided along which a cam follower runs (6). The cam follower drives the ejection lever via an intermediate link component, which is also a lever (7). The intermediate link component also incorporates a carriage (9), which along at least one track (10,11) is locatable on the cam follower or on the ejection lever.
