ABSTRACT:
An article is clamped in a predetermined position on a support, which is movable along a reciprocating path by a stepping motor. This movement of the support positions selected and spaced portions of the article at a fixed location at which a fastener element is attached to an edge of the article. The movement of the stepping motor is controlled by a computer program whereby the selected and spaced portions of the article are spaced from each other as desired.
