Abstract
A method for inserting an elastic ring having a peripheral opening within a workpiece. The elastic ring is first supplied to a ring receiving member, which then delivers the ring receiving member to an operating position. At the operating position, the diameter of the elastic ring is reduced by engaging portions on the ring receiving member. The diametrically reduced ring is then transferred to a finger member, which holds the ring in its reduced state and inserts the ring within the workpiece. The elastic ring is then released from the finger member and allowed to naturally expand within the workpiece.
