An arrangement for opening and cutting up packaging straps for scrap, in which a traveling frame moves transversely to a transport track. A cross beam with adjustable elevation has fastened to it a device for snipping and cutting up straps for scrap. A sensor determines the position of the package, of the packaging strap, of shears and shear blades. A control unit with preset control program switches the drives of the transport track, of the traveling frame, of the cross beam and of the device for snipping and cutting up for scrap, which is connected to the sensor. The shears have an extension forward of the lower shear blade with a blade-shaped pointed wedge, and drives for producing a nearly continuous force and for producing impacts attached to the shears. The wedge-shaped extension may form an acute angle with the package surface; this angle is adjustable relative to the package surface via a fulcrum. The force is introduced above the fulcrum parallel to the package surface into a guide carriage holding the shears. |
