Abstract: A winding machine for winding a paper or cardboard web on cores in a bed between two support cylinders has an ejector beam swingable about the input support cylinder and an ejection surface which extends radially with respect to the latter and is associated with a lifting roller on one side of that surface. The lifting roller has a free wheel lock which allows the lifting roller to rotate in the same sense as the input support cylinder but prevents rotation of the lift roller in the opposite sense.

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.
