Abstract
Two mating fastener elements are attached to material and each other at a setting station through an electric motor. The motor rotates a cam having its profile cooperate with a cam follower on an upper pivotally mounted arm to move a ram, which supports one of the fastener elements, towards a support, which supports the other of the fastener elements. The support is moved by a lower pivotally mounted arm attached to the cam by a crank arm so that it has a harmonic motion. The ram is stopped and held in its stopped position before a controlled setting force is applied through the support to move the other fastener element into engagement with the one fastener element.
