Abstract: The invention concerns a process for the manufacture of an explosion protection system for a container for inflammable liquid for gaseous substances, whereby individual sections on the surface of a foil strip that is made of a material with good heat-conducting properties, are permanently bent out of the plane of the untreated foil strip; from the such treated foil strip, at least one three-dimensional filling piece with a large interior surface is manufactured by division and/or deformation and said filling piece is inserted into the container, therefore filling at least the major part of the interior space of the container, as well as an explosion protection system of that kind.

Abstract: This invention concerns a process for the manufacture of filling material for hollow spaces, whereby a foil strip is at first continuously provided with intermittent longitudinal cuts and subsequently stretched in a vertical direction, as well as an arrangement of for the manufacture of such fulling material from a continuous foil strip, with a cutting device, that consists of two reciprocal rollers with cutting edges that are intermittently arranged in the circumferential direction, with a stretching unit for the vertical stretching of the cut strips of foil and with a drive as well as with a feed and removal unit.
