Abstract

A method for bonding the tail of a convolutely wound log to the body is provided. The method comprises the use of a nonadhesive phase-change material to mechanically bond the tail to the wound log. The nonadhesive phase-change material is heated to an amorphous state prior to its application. Once applied to the wound log, the nonadhesive phase-change material mechanical bonds with the tail and wound log and as heat is lost, changes to a non-amorphous state. The mechanical bond can be selectively reversed through the application of a strength degradation accelerator.
