Abstract

A device (33) forming part of a drive arrangement (3) which itself forms part of a stapler (1), which arrangement moves an anvil (16) which forms part of the stapler and against which stapling of a workpiece (42¹; 42²), e.g. a sheaf of papers, is effected in a reciprocating stapling movement (P), such that in the forward movement (N) the anvil moves from an initial position to abut against the workpiece, which device compensates the drive arrangement's movement of the anvil in the forward direction (N) appropriately to the thickness of the workpiece, such that the device (33) can be moved between a locked state in which the anvil (16) is moved by the drive arrangement (3) and a unlocked state in which the drive arrangement does not move the anvil, because the device is put by an elastic means (25) into a locked state when the anvil is in an initial position, and the device in the forward movement (N) is kept in a locked state until the anvil has been brought into contact with the workpiece (42¹; 42²), after which the device is put into an unlocked state by a release mechanism (35) which is acted upon by the drive arrangement.
