Abstract (en)
[origin: EP0778125A2] The bracing device, e.g. for bags, consists of devices which shape the workpiece into corrugations, e.g. freely rotating discs or belts on freely rotating rollers (14,15,44,45). The sectors of these which grip the workpiece act on the middle plane so that the workpiece is shaped into corrugations. There is a conveyor (29) to clamp the workpieces to each other. This may be a twin belt conveyor, with its clamping ends running over pairs of intermediate support rollers, of which at least one is pressed by the force of a spring against the others.
