Abstract
Plant for the continuous production of building elements which consist of two parallel flat grid meshes made from welded longitudinal and transverse wires, of straight web wires holding the grid meshes at a predetermined mutual spacing and of an insulating body which is arranged between the grid meshes and through which the web wires penetrate, with a production channel (2), on both sides of which supply reels (3, 3') and straightening devices (5, 5'), each for an endless grid sheet (G, G') standing on edge, and push-in devices (7, 7') are provided for drawing off the grid sheets in steps and for introducing these into grid-sheet lead devices (14, 14'), two cutting devices (11, 11') for severing grid meshes (M, M') of predetermined length being arranged upstream of the lead devices, and the grid meshes being capable of being advanced in the lead devices and in the production channel in steps to web-wire feeding and cutting devices (26, 26') by means of a grid-mesh conveying device (18) and downstream welding devices (30, 30') being capable of being advanced for the simultaneous welding of the two ends of all the web wires (S) to corresponding longitudinal wires (L, L') of the grid …
