Abstract

Folders for filing information on slips, holding maps, etc. are formed from a strip of thermoplastic material which is folded double and fastened along the abutting edges, by welding, to form a flat tubular space into which the sheet containing the information can be inserted. Before the double fold is effected, a narrow strip down the centre of the band of thermoplastic material, is plasticised by heating and passed between a pressing wheel with a narrow edge and a supporting surface along which there is a flute, so that a semicircular groove is formed in the band along the line of the fold. The two walls of the cavity into which the information slip is pushed, press against each other so that the slip is held securely and cannot fall out accidentally if the folder is titled at an angle. The opened edge facilitates insertion of the slip, and gives a certain stiffness to the folder lengthways.
