Abstract: A method and apparatus for wrapping bales of pulp are disclosed, the method comprising transporting the bales between upper and lower conveyors, applying a first wrapping sheet to the lower surface of the bale, applying a second wrapping sheet to the upper surface of the bale, measuring the height of the bale prior to transporting it between the upper and lower conveyors, and adjusting the distance between the upper and lower conveyors based upon the measured height of the bale such that both of the wrapping sheets are uniformly disposed on the upper and lower surfaces of the bale. The apparatus includes an upper conveyor, a lower conveyor juxtaposed with the upper conveyor, such that the bales may be transported between the upper and lower conveyors, a transmitter for measuring the height of the bales upstream of the upper and lower conveyors, and a positioner for adjusting the distance between the upper and lower conveyors based on the measured height of the bales.

Abstract: Apparatus for tying objects with wire is disclosed including a feeder for feeding and tightening the wire around the object, the feeder being driven by an electric servomotor which can be rotated through a predetermined number of revolutions for feeding and tightening the wire, an adjustable guide rail for guiding the wire around the object and for tightening the wire when the guide rail is opened, a locking unit for locking the wire around the object, a wire twister for twisting the wire into a knot, the wire twister being driven by an electric servomotor so that it can be rotated through a predetermined number of revolutions for twisting the wire into a knot, and a wire cutter for cutting the wire after the knot has been formed.
