KR950031807A - Method and apparatus for manufacturing dimensionally stable cylindrical filler bodies and expansion materials - Google Patents

Abstract

Consisting of flaky, preferably strips of corrosion-resistant material, in particular of metal, paper, fingerboard, composite material or combinations thereof, and of receptacles for protecting explosive fuels without vibrating many mechanical parts. A method and apparatus are provided for carrying out a method of manufacturing a dimensionally stable cylindrical filler body for expanding a surface.

The flake strips of the present invention receive a perforated cut portion and are cut alternately in the conveying direction and crosswise, the cut portion being stretched to a certain width, bent, cut into pieces, bent in a circle, twisted at the end, into a cylindrical molded body. It is wound up continuously.
