Abstract: An apparatus for attaching rivets, buttons or the like to textiles or the like, having a plunger which performs the riveting stroke and whose upward and downward movement is controlled by the interaction of the top end of the plunger with a cam plate rotationally driven by an electric motor, the apparatus performing a sequence of attachments upon actuation of a switch or the like, the electric motor (39) running at a fixed preset angular velocity being stopped briefly in the top dead-center position of the plunger (24) by a braking device or the like in order to reduce the cycle frequency of the plunger stroke. To this end, the control unit switches off the drive motor (39) in the top dead-center position of the plunger for a preprogrammed time and switches it on again after the preprogrammed waiting time has expired and actuates a brake in particular during the waiting time.

Abstract: A riveting press wherein the reciprocable ram of the upper tool can be rotated by a stepping motor to transmit torque to an article holding device which is reciprocable independently of the ram to pick up randomly oriented articles from a transferring device. The latter accepts successive randomly oriented articles from a chute and carries a sensor which interrupts rotation of the article and of the holding device when its follower detects a marker on the article. An adjustable selector switch or a computer is provided to induce the motor to turn the holding device and the article therein to a final angular position prior to application of the article to a garment.
