Abstract: A waste stripping station for a machine for die-cutting plate-like workpieces includes a perforated board which is positioned between an upper movable tool and a lower movable tool for supporting a plate-like workpiece carried into the station by grippers. Waste bits of the workpiece are pinched between pins or elements of the upper and lower stripping tools and are carried vertically downward through perforations in the board. In order to provide clearance for the grippers, the perforated board is mounted to pivot around an upstream edge in order that its downstream edge may be lifted from a position allowing passage of the grippers to a position slightly lifting the plate-like workpiece.

Abstract: A combination of a bar and a pair of fastening devices, which are integrated into a chain and replace a link of the chain on each end of the bar, includes an outer vertical plate portion and an inner vertical plate portion interconnected by an inner connection to form spaces for receiving an upstream axle and a downstream axle of the chain links, each axle being eventually covered by a meshing cylinder. The bar has a finger protruding from each end. The inner plate portion is completed on its inner face by a pair of spaced knuckles which receive a portion of the bar therebetween and are connected to the bar by a crosswise linking axle extending between the two knuckles and through the bar. The outer and inner plate portions each have an aperture for receiving the rigid finger which extends from the end of the bar.
