ABSTRACT:
Disclosed is a method for manufacturing a composite pad from stock made of a relatively thin, sheet-like first layer, a relatively thin, sheet-like second layer and a relatively thick layer of an elastic, cushioning material sandwiched between the two. The outer layers are made of material, such as heat sealable material, that forms a seal under predetermined conditions. The pad is manufactured by first forming a sealed perimeter from the stock using a sealing tool and then using the same tool to separate the pad from the adjacent stock while simultaneously orienting the seal away from the side of the pad which will contact the wearer of a brace into which the pad is fitted.
