ABSTRACT:
A method and apparatus for forming a tensioned garter. 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 mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively clamped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. Once the garters are formed the mandrels may be rotated on their radial axes for alignment with downstream operations. Sealing through elastic members is avoided by interrupting the bonding of elastic members to an elasticized laminate at locations where ribbons are to be clamped. High compression of elastics where they are not sealed to the laminate causes elastic members to burst and contract. Elastic contraction leaves an area in which ribbons may then be bonded together without sealing through elastic members.
