Abstract

1397386 Seaming non-metallic sheet-material RADYNE Ltd 7 June 1974 [4 July 1973] 31824/73 Heading B5K A combined high frequency welding and cutting tool comprises a fixed high frequency welding electrode 1, a movable cutting knife 6 at least partially surrounding the electrode 1, means for driving the knife 6 from a retracted position in which the cutting edge 7 of the knife lies behind the work-engaging surface of the electrode to an extended position in which the cutting edge lies proud of this surface, and means for maintaning the knife 6 in its extended position with its cutting edge against a workpiece when the tool and workpiece are compressed between the platens of a welding press. As shown, the electrode 1 is rigidly mounted on a base-plate 2 by spacers 3 which pass through openings 4 in a plate 5 carrying the peripheral knife 6. In use, after a weld has been completed, a pair of double-acting diaphragm cylinders 11 urge the plate 5 upwards to assist the insertion of a pair of wedges 8a, 8b towards each other by hydraulic or pneumatic cylinders 10a, 10b. The force transmitted by the wedges 8a, 8b drives the knife 7 above the welding surface of the electrode 1. When the wedges have been fully inserted, pressure is applied to the welding press so that cutting is effected. The full insertion of the wedges is indicated when they strike air limit switches S1 S2, respectively. In modifications (not shown), (a) more than two wedges are connected together to form a lattice driven as a whole by one or more pneumatic or hydraulic cylinders and (b) more than two cylinders 11 are provided.
