  • Patent number: 5249341
    Abstract: A wire-removing machine for bales consist of a positioning device for the bales (1), a cutting device (4) for severing the tying wires tensioned round the bales, a gripper device (5), by means of which the tying wires, after these have been severed, can be lifted off from the bales, and a winding device (6) which grasps all the lifted-off wires in the lifted-off portion by means of a common fork-shaped longitudinally displaceable winding spindle (22) and winds them to form reels. To improve the operation of winding the severed tying wires, there is a row of guide fingers (7) which are arranged in a comb-like manner and which, after the severed tying wires have been lifted off, are arranged in the region between the winding spindle (22) and the bale (1), the tying wires running through between the guide fingers (7) during the winding operation.

  • Patent number: 5131135
    Abstract: The invention relates to a wire-removing device for units (7) consisting of two stacks standing closely next to one another and composed of a plurality of bales (11, 12, 13) arranged one on top of the other, each unit (7) being surrounded in one plane by a bundle (15) embracing all the bales and composed of a plurality of parallel individual wires. So that the removal of wire from the units (7) can be carried out fully automatically and at the same time in order to wind the wire bundle to form a coil, there is in the lower region of the unit (7) a wire-cutting means (18) which is combined with a wire-lifting means (3) for lifting the severed wire bundle (15). Furthermore, there is a gripping means (4) which grasps the wire bundle (15) on both sides of the wire-lifting means (3) and which brings it into a predetermined extraction position. The severed wire bundle (15) is grasped by a winding means, wound to form a roll and ejected from the device.

  • Patent number: 4850087
    Abstract: A wire-removing machine for pulp bales consists of a positioning device (1) for the bales, a cutting device (2) for cutting through the tying wires stretched around the bales, and also a winding device (4) for winding the cut-through tying wires. In order to optimize the co-ordination between cutting and winding devices and so that cutting through and subsequently winding the wires can be carried out without problem even when the tying wires are arranged obliquely, a gripping device (3) is provided with which the tying wires are held in position and are lifted a short distance away from the bale after being cut through, the winding device (4) seizing the cut-through wires in the section between the bale and the gripping device (3) and winding them into coils.

  • Patent number: 4261395
    Abstract: A wind-up head which is in particular provided for unwiring bales in conjunction with a cutting apparatus, comprises substantially a cylindrical wire receiving portion which at its work end has at least one receiving slit for gripping the wire and is arranged between two wire guide slits. In order to permit that the wind-up head is able to grip and coil wire lengths without the aid of further apparatus and in particular is able to grip directly the wires still engaging a bale when using it for unwiring bales without the aid of a special lift-off apparatus, the wire receiving portion is formed as a hollow cylinder from the work end of which at least two helical slits start penetrating the cylinder wall. The hollow cylindrical wire receiving portion is surrounded at a distance by an external cylinder which has at least two helical slits likewise starting from its work end and having an opposite hand to the slits of the inner hollow cylinder.
