Abstract

1447865 Seaming non-metallic sheet material; making bags SPACIALS Ltd 2 Nov 1973 [27 Oct 1972 12 July 1973] 49992/73 and 50202/73 Headings B5K and B5D The subject-matter is identical to that disclosed in Specifications 1,447,863 and 1,447,864, but the claims relate to forming individual heat sealed articles, e.g. tubes or bags, from two superimposed heat sealable layers by feeding the layers into zig-zag form, welding the layers along the transverse crests on one side of the zig-zag, separating the welded layers into individual articles, and removing the articles in a folded form with adjacent bags overlapping one another.
