The present disclosure relates to adjusting and maintaining a position of a cutting surface used to create lines of weakness for rolled products. A perforating apparatus includes a housing rotatably supported by a frame, wherein the housing is adapted to rotate about a first axis. A support member including a first cutting surface is rotatably supported by the housing, wherein the support member is adapted to rotate about a second axis offset from the first axis. A roll including a second cutting surface is positioned adjacent the support member, wherein the roll is adapted to rotate about a third axis. The second cutting surface is adapted to contact the first cutting surface as the roll rotates about the third axis. The perforating apparatus is configured such that the functions of adjusting the position of the first cutting surface and holding the first cutting surface in a fixed position are separate.

A method of creating a topsheet for an absorbent article is disclosed. The method includes the steps of: obtaining a pre-cursor web of material, the pre-cursor web of material having a first surface and an opposing second surface, wherein the pre-cursor web of material is a composite or laminate web having a first layer and a second layer, wherein the first layer is a film and the second layer is a nonwoven material having a plurality of fibers; forming a first plurality of apertures having sidewalls extending in a first direction from the pre-cursor web of material; forming a second plurality of apertures having sidewalls extending in a second direction from the pre-cursor material, wherein the first direction and the second direction are different; and forming a plurality of embossments in the pre-cursor web of material, wherein the embossments are oriented in a third direction opposite the first direction.

A method for manufacturing a wound dressing having a substrate, and a wound dressing manufactured by such a method are described. The method has a step of providing a sacrificial layer of material to be perforated by means of a hot pin perforator, in order to remove any molten residues on the heated pins of the hot pin perforator, before the same pins are used to make holes in the substrate. The presented method is cost effective, robust and reduces the risk of contaminating substances being embedded in the substrate during the hole making process.

An apparatus for producing an easy-to-tear plastic film comprising a pattern roll rotatably supported by a pair of stationary frames, an anvil roll moving along a pair of movable frames, a first driving unit for rotating the movable frames, and second driving units each mounted to the movable frame to move the anvil roll up and down; high-hardness, fine particles projecting from a rolling surface of the pattern roll having such average height and maximum height as enabling the formation of unpenetrating fine pores in a plastic film; with the anvil roll inclined to the pattern roll in a horizontal plane by the operation of the first driving unit, large numbers of unpenetrating fine pores being formed transversely uniformly in the plastic film passing through a gap of both rolls.

An apparatus for producing a macroporous plastic film comprising a first roll rotatably supported by stationary frames; a second roll movable up and down along movable frames; a first driving means for rotating the movable frames; and second driving means mounted to the movable frames for moving the second roll up and down; one of the first and second rolls being a pattern roll having large numbers of high-hardness, fine particles on its rolling surface, and the other being an anvil roll; large numbers of fine pores being formed in the plastic film by the high-hardness, fine particles, in a state where the center axis of the second roll is inclined to the center axis of the first roll in a horizontal plane by the operation of the first driving means.

The present application provides a napkin dispenser for dispensing a number of folded napkins from a sheet material to an end user. The napkin dispenser may include a loading station for loading the sheet material, a folding station for folding a napkin from the sheet material, and a presentation station for presenting one or more of the folded napkins to the end user.

The invention relates to a method for producing a stamped metal sheet which has at least one interrupted cutting line in (17) for producing perforations or holding points, which is arranged on a base sheet (15), characterized in that a laser beam is used for producing at least one interruption (14). The invention also relates to a stamped metal sheet.
