ABSTRACT:
A method for bonding a tensioned elastic garter to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment a mandrel has a top surface and side walls. The side walls have recesses. A tensioned garter is wrapped around the side walls such that it spans the recesses. A substrate is placed against the top surface of the mandrel. An anvil surface is positioned to backup the substrate. Sealing tools pass through the recesses and intercept the tensioned garter and press it against the substrate backed up by the anvil surface. Thermobonding or adhesive sealing occur at spots where sealing tools press the tensioned garter against the substrate and anvil. The garter is stripped from the mandrel either by moving the substrate away from the mandrel or by having the sealing tools push the garter off the mandrel side walls. Portions of the garter between sealing spots take straight line paths once released from the garter.
