Abstract: A strain relief system for flexible circuits has a tapered cover laminate affixed to either side of the flexible circuit to form a cover laminate/flexible circuit assembly, with the widest portion of the cover laminate being at the point of maximum bending stress of the flexible circuit to provide a stiffer assembly at that point. A rigid stiffener having a bending radius also is affixed to either side of the cover laminate/flexible circuit assembly at the point of maximum bending stress to provide strain relief, the bending radii being laterally offset from each other so that bending in opposite directions occurs at different locations of the flexible circuit. The result is a gentle, low stress bend in the flexible circuit when subjected to regular bending.

Abstract: Apparatus and method for developing and applying an adhesive strip and protective cover strip on the backing side of a hospital underpad. The apparatus is positioned along the production line where the folded hospital underpad material has been fabricated and is ready for cutting into individual pads. The apparatus draws a continuous ribbon from a supply spool, applies a strip of liquid plastic melt adhesive to the upper side of this ribbon, and then inverts the ribbon and directs it, with the adhesive strip on the underside, onto the intermediate layer of the folded underpad material where rollers press it into the desired position.
