A method for perforating a film of plastic material in which the film is perforated whilst it is slid through a perforating device by a plurality of pressurised hot gas jets having a temperature above the melting temperature of the main film, in which the hot gas jets are correlated with the sliding speed of the main film, and in which reinforcing bands obtained from an auxiliary film of plastic material are connected to the perforated main film, making the reinforcing bands adhere between parallel rows of base holes. During perforating, the main film of plastic material is pressed against a perforating template, making the main film of plastic material instantaneously penetrate openings of the perforating template by said hot gas jets. A hot gas perforating device and a suitable apparatus for perforating and stretching a film of plastic material are also provided.

The invention relates to a corrosion protection arrangement comprising an adhesive layer (11). The adhesive layer (11) contains at least one volatile corrosion inhibitor (12). The adhesive layer (11) sticks to a surface (23). The adhesive layer (11) bonds an outer layer (13) to the surface (23). The outer layer (13) has a multitude of orifices (14) for release of the volatile corrosion inhibitor (12). The outer layer (13) has protuberances (15) which project out of a plane (16) of the outer layer (13) by a height (17).

The present disclosure relates to processing a substrate including at least one sheet of paper, cardboard or carton by directing a jet stream of liquid nitrogen to a surface of the substrate via a jet nozzle; and by moving the jet nozzle at a distance from the surface. The jet stream can be unmodulated or modulated. For example, the jet stream can be modulated by a modulation unit such as to reduce the impact of the jet stream on the surface. In this way, the jet stream can be applied to score folding lines into the substrate. An unmodulated or on/off modulated jet stream can be applied to cut lines into the substrate. Thus, by applying an appropriate modulation to the jet stream, the processing can switch between cutting the substrate and scoring folding lines into the substrate.
