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 shape having a shape width, W. 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 driving means 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. The distance, D, is at least the translational distance that one tooth travels to cover the shape width, W.

摘要： The present disclosure relates to a cutting system for providing holes in a core material layer. The cutting system has a cutting tool having a cutting knife configured to cut through the core material layer, and an anvil having a rigid support surface for receiving the cutting knife of the cutting tool. The cutting system further has an elastic member that is positioned to absorb at least a part of a force applied when the cutting tool is pressed against said anvil.

摘要： A method for making an extrusion coated perforated nonwoven web. The method comprises the steps of extruding a molten polyethylene coating onto a nonwoven web, and aperturing the molten polyethylene coating through heat and pneumatic pressure differential to create microperforations therein at a density of between about 35 and about 120 perforations per linear inch. The resulting microperforated nonwoven web is then thermomechanically perforated by feeding it through perforating rolls, at least one of which has raised protuberances to create macroperforations that extend through at least the polyethylene coating. The macroperforations have a density of between about 6 and about 35 perforations per linear inch. The perforated nonwoven web is useful as a topsheet for absorbent articles.
