Baling press with bale binding device and operation thereof

摘要

A baling press of the kind comprising a pressing channel containing a reciprocating pressing plunger has a bale binding device which binds the bales with bands each consisting of two separate lengths of wire from different rolls twisted together. The binding device includes a twisting mechanism for twisting the wires together and this twisting device comprises a disc which is rotatable about an axis situated in the plane of the binding and this disc has a single finger which projects outwards from the axis of rotation of the disc and is forwardly curved in the direction of rotation of the disc in order to seize the two wires and twist them together. The inner edge of the finger leads into a slit which extends through the disc up to the center of rotation of the disc and this slit tapers in a region adjacent the center of rotation of the disc to a width which only just exceeds the thickness of one wire. The binding device is operated in such a way that during the last turn of the disc at the end of a twisting operation, a needle which draws a loop from one of the wires is moved towards the disc so that the subsequent rotation of the disc at the end of its last turn swings the loop out of the path of the needle before the disc is brought to a standstill.
