ABSTRACT:
A splice is made, between a tail end of first web and a lead end of a second web coiled about an unwind axis, by winding a portion of the first web adjacent the tail end of the first web about a splicing roll mounted for rotation about a splice roll axis oriented substantially parallel to the unwind axis, and then joining the tail end to the lead end by compressing an adhesive between an inside surface of the tail end and an outer surface of the second web. Compression of the adhesive is accomplished by urging the splice roll against the coiled second web while the coiled second web is rotating about the unwind axis in an unwind direction and the splicing roll is rolling about the splice roll axis in a direction opposite to the unwind direction.
