Actuating assembly for the prime movers of riveting presses and the like

摘要

A riveting press wherein the motor for the movable riveting tool is started in automatic response to closing of two discrete switches. One of the switches can be closed by a rivet which is already applied to a workpiece, such as a piece of textile material, and such one switch is located at a variable distance from the riveting tools. The other switch is also located at a selected distance from the riveting tools and can be closed by a marginal portion of the workpiece whereby the tools automatically apply a rivet to that part of the workpiece which is disposed therebetween while the two switches are closed.
