Abstract
A toggle press is provided with two levers (14, 16) which are pivotably connected by means of a joint (18), the first of which (14) is connected at its free end to a pressing tool (22) and the second of which (16) is rotation-resistantly mounted at its free end on a shaft (28) which can be rotated by a drive unit. The rotation-resistant connection between the second lever (16) and shaft (28) is releasable when the toggle lever reaches the extended position. The second lever (16) is disposed on a section of shaft (28) contrived as an eccentric cam (44).

A toggle press with two levers (14, 16) which are pivotably connected by means of a joint (18), the first of which (14) is connected at its free end to a pressing tool (22) and the second of which (16) is rotation-resistantly mounted at its free end on a shaft (28) which can be rotated by means of a drive unit, characterised in that the rotation-resistant connection between the second lever (16) and shaft (28) is releasable, and in that the second lever (16) is disposed on a section of shaft (28) contrived as an eccentric cam (44).
The toggle press of one of the preceding claims, characterised in that when levers (14, 16) of toggle lever (12) reach the extended position, a stopper element (40) on one of levers (14, 16) comes into contact with a counter-stopper element (42) on press frame (10).
