摘要： A method for providing a nonlinear line of weakness on a web material includes: providing a counter component comprising a nonlinear shape, where the nonlinear shape has a shape width, W; providing a blade in operative relationship with the counter component and comprising a plurality of teeth; rotating at least one of the blade and the counter component into interacting relationship with the other of the blade and the counter component; feeding a web between the counter component and the blade such that while in interacting relationship the blade cooperates with the counter component to perforate the web, wherein the web is moving in a machine direction; and reciprocally shifting one of the counter component and the blade for a distance, D, in a shifting direction, wherein D is at least the translational distance that one tooth travels to cover the shape width, W.

摘要： A perforating apparatus may have a first roll comprising a first design and a second roll comprising a second design, each roll being in close proximity with a support member and each roll comprising a blade or an anvil. A web material may travel a first path between the first roll and the support member or, alternatively, may travel a second path between the second roll and the support member.

摘要： A method for providing a nonlinear line of weakness on a web material including providing: a base, a support, a blade, and a driving means. The base may comprise at least one counter component having a length (LCC) where the counter component comprises a nonlinear shape having a shape width (W). The support may be operatively engaged with the base. The blade may have a length (LB) and may be disposed on the support so as to either contact or to come in close proximity with the counter component. At least one of the counter component and the blade may have a nonlinear shape and at least one of the counter component and the blade may comprise multiple segments.

摘要： A perforating apparatus has a base having at least one counter component. The counter component has a length, Lcc, and a nonlinear repeat length. A support is operatively engaged with the base. A blade having a length, LB, is disposed on the support so as to cooperate in interacting relationship with the counter component. The blade has a plurality of teeth. A web material is perforated as it passes between the base and the support and the blade cooperates with the counter component. A drive is associated with one of the support and the base to reciprocally shift the one of the support or the base for a distance, D, in a shifting direction.

摘要： A perforating apparatus has a first roll and a second roll, each being operatively engageable with a support. The first roll has a first longitudinal axis about which the first roll rotates and a first anvil disposed on the first roll and having a first design. The second roll has a second longitudinal axis about which the second roll rotates. A second anvil is disposed on the second roll. The second anvil has a second design. At least one blade is disposed on the support so as to cooperate in interacting relationship with one of the first anvil and the second anvil when the support is operatively engaged with the one of the first anvil and the second anvil. The apparatus comprises two alternative paths for the web material.
