Abstract
Two mating fastener elements are attached to material at a setting station through a first electric motor. The motor rotates a cam for causing a first pivotally mounted arm to move a support, which supports one of the fastener elements, towards a ram, which is moved by a second pivotally mounted arm attached to the cam rotated by the motor. A second electric motor, which makes at least one revolution and may make a plurality of revolutions during each energization of the first motor, is energized when the first motor, which makes one revolution during each energization, is energized. Each of two hoppers has a plurality of one of the fastener elements. The second motor activates a knife blade in each of the two hoppers so that one of the knife blades moves upwardly in its hopper while the other is moving downwardly to feed the fastener elements within the hopper therefrom for receipt by the support or the ram.
