Paper product

A method for perforating a web with a perforating apparatus includes: rotating a cylinder about a longitudinal cylinder axis, wherein the cylinder comprises at least one shaped blade; operatively engaging a moveable support with the cylinder; positioning an anvil disposed on the support so as to cooperate in contacting relationship with the shaped blade, wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; feeding a web between the cylinder and the support; and perforating the web as the anvil cooperates in contacting relationship with the shaped blade disposed on the rotating cylinder.

Method of perforating a nonlinear line of weakness

A web may include a curvilinear line of weakness comprising a plurality of perforations and a first amplitude. The first amplitude may be less than a second amplitude of a perforating apparatus that formed the sinusoidal-shaped line of weakness comprising the first amplitude.

Nonlinear line of weakness formed by a perforating apparatus

A method for perforating a web with a perforating apparatus includes: rotating a cylinder about a longitudinal cylinder axis, wherein the cylinder comprises at least one shaped blade; operatively engaging a movable support with the cylinder; positioning an anvil disposed on the support so as to cooperate in contacting relationship with the shaped blade, wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; feeding a web between the cylinder and the support; and perforating the web as the anvil cooperates in contacting relationship with the shaped blade disposed on the rotating cylinder.

A method of perforating a web includes: rotating a cylinder comprising a longitudinal cylinder axis and at least one shaped anvil disposed on the cylinder; operatively engaging a support with the cylinder, wherein the support is moveable with respect to the cylinder; positioning a blade disposed on the support so as to cooperate in contacting relationship with the anvil, wherein the blade is substantially parallel to the longitudinal cylinder axis, and wherein at least one of the blade and the anvil comprise a plurality of teeth, and wherein adjacent teeth are separated by a recessed portion; and feeding a web between the cylinder and the support while the blade cooperates in contacting relationship with shaped anvil to perforate the web.

A web includes a curvilinear line of weakness. The curvilinear line of weakness includes a plurality of perforations. Each of the plurality of perforations is separated by a bond area. Each of the plurality of perforations has a perforation length and each bond area has a non-perforation length.

A perforating apparatus includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil is disposed on the cylinder. Further, a support operatively engages with the cylinder, and the support is moveable with respect to the cylinder. A blade is disposed on the support so as to cooperate in contacting relationship with the anvil, and the blade is substantially parallel to the longitudinal cylinder axis. At least one of the blade and the anvil comprises a plurality of teeth, and adjacent teeth are separated by a recessed portion. A web is perforated as the web passes between the rotating cylinder and the support and the blade cooperates with the anvil.

Perforating apparatus for manufacturing a nonlinear line of weakness

A web includes a curvilinear line of weakness. The curvilinear line of weakness includes a plurality of perforations. Each of the plurality of perforations is separated by a bond area. Each of the plurality of perforations has a perforation length and each bond area has a non-perforation length. In one embodiment, at least two of the perforations lengths are substantially equal. In an alternate embodiment, at least two of the non-perforations lengths are substantially equal. In yet another embodiment, at least two of the non-perforations lengths are substantially unequal and at least two of the perforation lengths are substantially unequal.

A winder for winding continuous webs or interleaved web segments having a machine direction and a cross-machine direction coplanar and orthogonal thereto into rolls is disclosed. The winder provides a plurality of winding spindles orbiting about a winding turret axis and a plurality of surface contact rolls cooperatively associated with a respective winding spindle. Each surface contact roll is capable of cooperative engagement with the respective winding spindle when the web material is disposed therebetween. The longitudinal axis of each surface contact roll is adjustable relative to the axis generally parallel to the winding turret axis when the web material is received by the winding spindle cooperatively associated thereto.

Rewind system

A mandrel cupping assembly for releasably engaging unsupported ends of a plurality of mandrels is disclosed. The mandrel cupping assembly comprises a cupping arm turret having a cupping arm turret central axis, a mandrel cup cooperatively associated with each mandrel of the plurality of mandrels, and a first actuator.
