  • Patent number: 4409061
    Abstract: A machine for the tying of packages, having a gripper which places the tying means around the package, the gripper being moved by a pull means and stopped in a position where the ends of the tying means are connected to each other. A consistent return of the gripper to the basic position is due to the fact that the basic position of the gripper lies approximately at the center point of an arcuate section of the path of the gripper pull means so that the gripper position is retained even though the pull means may continue to move.

  • Patent number: 4356685
    Abstract: Machine for tying packages or the like in which the tying means which is held fast at one end is guided by means of a tying means guide device around the package in the manner that the tying means guide device which is driven cyclically back and forth, its forward movement, accumulates a layer of tying means which surrounds the package, which layer is wound around the package upon the following return run, and in which there is preferably provided, below the support table for the package, a sealing device which connects the ends of the tying means and cuts off one end, the sealing device having grippers associated with it for holding the tying means fast. Each one of the grippers together with the end of the tying means held fast by it, carries out in cyclic dependency, a rotary movement which turns the gripper slot around. One of the two grippers, respectively, which are additionally axially displaceable, in a crosswise rotary position of its gripping slot S, pushes the tying means from the sealing device.
