Abstract

930,149. Making lattice members; welding by pressure; shearing. EVG ENTWICKLUNGS - UND VERWERTUNGS - G.m.b.H. Dec. 12, 1960, No. 42701/60. Classes 83 (2) and 83 (4). In making a reinforcing element which comprises a pair of parallel strips with transverse pieces welded therebetween, the strips are conveyed to the welding station in converging directions, a succession of transverse pieces is introduced between the strips with clearance at both ends, the strips at the welding station are pressed from the outside by electrodes against each transverse piece in turn to weld thereto and the strips are moved forwards by a distance equal to the separation of the transverse pieces along the strips. Two strips 1, 11 are fed stepby-step from straightening rolls through guides 2, 2<SP>1</SP> to the welding station and rod or strip 3 is fed step-by-step through straightening rolls 5 and conveyer rolls 6 to a cutter 7 having a fixed knife 9 and a movable knife 10 which forms the connecting pieces 4, the strip 3 passing through a swingable guide 11 which after each cut returns the strip by a spring 12. The pieces 4 are fed forward in a guide 8 and with the strips 1, 11 stationary a piece is fed upwardly to the plane of the strips by a plunger 13 operated by a cam and moved by a lever mechanism towards a stop to clamp the piece. Electrodes 14, 14<SP>1</SP> connected to a transformer 18 are pivoted by cams carried on the shaft carrying the plunger moving cam, to press the strips against the piece and welding is effected. The reinforcing element is then fed one step by rollers 17 and the next piece 4 is fed and welded. The welding may be controlled by photo-electric means. Specification 728,866 is referred to.
