ABSTRACT:
An operator-tended machine, e.g., a machine for applying snap fasteners, rivets or the like to workpieces, has an upper tool which moves against a lower tool acting as an anvil for it. A fingerguard moves ahead of the upper tool to protect the fingers of an operator. A workpiece support, with reference to which the prescribed safety distance of the fingerguard is calculated, can move downwardly and yield to the upper tool against a biasing force.
