ABSTRACT:
A method of winding a continuous web on a succession of cores comprises the steps of sequentially rotating a core to which the web is attached to longitudinally advance the web and wind it on the core while applying a strip of adhesive to a transfer roller and then stopping rotation of the core. Subsequently a crosswise row of perforations is formed in the web offset from the core and then the web is longitudinally advanced while pressing the roller against the web to transfer the adhesive strip to the web at and immediately upstream and downstream from the perforation row. The web is subsequently differentially. longitudinally advanced web upstream and downstream of the perforation row to tear the web longitudinally apart at the perforation row, thereby forming a trailing web end attached to the web wound on the core and a leading web end each carrying some of the adhesive strip. The trailing web end is then pressed against the web on the core to adhere it thereto and the core is replaced with a fresh core and then the leading web end is adhesively attached to the fresh core. At the end the web is again advanced the web and wound on the fresh core while applying another adhesive strip to the transfer roller.
