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.
Claims23
A method for bonding a tail of a convolutely wound log of web material to the log, the method comprising:
- providing a web material;
- winding the web material into a convolutely wound log having a body and a tail;
- providing a nonadhesive phase-change material in an amorphous phase;
- applying the nonadhesive phase-change material in the amorphous phase to the web material at an application site proximate to the tail;
- and
- wherein the nonadhesive phase-change material alters to a non-amorphous phase to create a bond between the tail and the body.
A method for bonding a tail of a convolutely wound log of web material to the log, the method comprising:
- providing a web material;
- winding the web material into a convolutely wound log having a body and a tail;
- providing a nonadhesive phase-change material in an amorphous phase;
- applying the nonadhesive phase-change material in the amorphous phase to the web material at an application site proximate to the tail, wherein the nonadhesive phase-change material alters to a non-amorphous phase to create a bond between the tail and the body;
- and
- subsequent to the creation of the bond between the tail and the body, accelerating a degradation of the strength of the bond.
