Abstract
1,039,718. Seaming non-metallic sheet material. H. ESCHER, [trading as FIRMA GEORG ESCHER]. March 31, 1965, No. 13562/65. Heading B5K. A device for sealing and/or severing films of thermoplastic synthetic plastics material comprises a heating wire 1 extending over the entire length of the weld seam and which comprises loops 4 extending perpendicularly to the welding plane and countersunk and secured in the welding frame 2 so that when the wire 1 is in the cold condition expansion compensating gaps are formed. The loops 4 are accommodated in recesses 6 in the frame 2 and form arms 5 spreading apart which approach each other due to expansion when current is supplied to the wire 1. Pins 8 may be provided to hold the wire 1 fast. The wire 1 may be a flat strip, e.g. 0À1 x 1 mm. in cross-section. In addition to the wire 1, the frame 2 is provided with a severing wire 3, Fig. 1 (not shown). In use, a presser plate, strip or frame (not shown) presses the films to be welded against the frame 2 and the wires 1, 3.
