A method for producing a porous metal foil comprising causing a metal foil together with a soft sheet to pass through a gap between a pattern roll of a hard metal, which has high-hardness, fine particles having particle sizes of 50-500 m on the surface, and a hard metal roll opposing the pattern roll, to press the metal foil and the soft sheet, thereby forming fine pores in the metal foil; the soft sheet being a laminate sheet of a relatively hard plastic layer and a relatively soft plastic layer; and the pressing of the metal foil being conducted with the relatively hard plastic layer on the side of the metal foil, and the relatively soft plastic layer on the side of the hard metal roll.

A deep-drawing machine having a forming station configured for forming containers into a first sheet-shaped material, and a cutting station disposed downstream of the forming station in a working direction. The cutting station is configured to cut or to perforate an area of the sheet-shaped materials disposed between the containers. The cutting station may include a rotation cutting device that comprises a cutting cylinder and an opposing cylinder. A method for operating a deep-drawing machine that comprises the following steps: forming containers into a first sheet-shaped material by a forming station, and cutting or perforating of the sheet-shaped materials in an area between the containers after forming of the containers using the rotation cutting device.

In one example, a rotary cutting device includes a helical cutting blade rotatable against a workpiece to cut the workpiece and translatable to engage the workpiece and to disengage the workpiece.

Systems and methods utilizing stationary and/or moveable cutting components provide limited interference with web processing operations, such as pad spin and pitch alteration. Heat, laser, fluid, or mechanical cutting operations may be used, including respectively, a heated element (e.g., wire, ribbon, bar, or embossing or perforating element) that may be triggered inductively, water or steam jets, or improved knife/anvil cooperation.

Apparatuses and methods are provided in relation to a wrapping machine for wrapping packages, and more particularly, to a film-breaking apparatus for use with a wrapping machine having a dispenser carriage movable along a wrapping axis for wrapping a film around a package. The film-breaking apparatus includes a trigger arm coupled to the dispenser carriage; a puncturing arm including a puncturing member, the puncturing arm pivotably connected to the trigger arm such that the trigger arm is free to rotate relative to the puncturing arm in a first rotational direction, and rotationally coupled to the puncturing arm in a second rotational direction. The puncturing arm is configured to puncture the film being dispensed by the dispenser carriage with the puncturing member when rotated by the trigger arm.
