ABSTRACT:
A machine for the attachment of rivets, buttons or the like on clothing pieces, with an upper tool to be moved onto the lower tool, which upper tool sits on a vertically guided tool ram with electrical drive. Two different strength magnets are coordinated to the upper tool ram, the latter being spring-biased in the reverse direction, such that the weaker electromagnet which sits in the range of a cross-sectionally-smaller step of the upper tool ram surrounds the upper tool ram in ring-like manner and the stronger electromagnet has a core which core forms a pot-shaped recess for moving a plate armature therein, the latter being arranged on the free end of the upper tool ram.
