ABSTRACT:
A method of and an apparatus for the performance of the method for the fabrication of dimensionally stable, cylindrical filler bodies for increasing the surface area in receptacles, e.g. for the protection against explosive combustions, consisting of foil-like, preferably corrosion resistant material strips, especially consisting of metal, paper, paper board, synthetic material or a combination by coating, which allows a continous fabrication without requiring oscillating masses in the machine parts. The aim is reached by a foil strip which receives perforated cutting spots, staggered transverse to the conveying direction, the cutting spots stretched to the breadth and folded, lopped in pieces, cylindrically bent so as to be round, twisted at the ends and continously rolled into cylindrical bodies.
