Abstract
A necking machine (1) having a plurality of processing stations on a rotating tool carrier (7). The motion of the tool carrier (7) with respect to the work pieces is carried out by a crankshaft (25). This is carried out by a non-constant gear. The gear includes two non-round gearwheels (21, 23) that improve a rotational-speed profile of the crankshaft (25) and thus a velocity profile, in particular, in an area of the dead center.
