  • Patent number: 8016119
    Abstract: In an apparatus for separating plastic film material from waste, a plurality of hooks is mounted on a hook carrier for circulating the hooks along a trajectory through an engagement area near a supply track and through a disengagement area downstream of the engagement area. The engagement area is located higher than the supply track and/or in supply direction beyond the downstream end of the supply track, such that, in operation, a remainder of the waste passes by the trajectory of the hooks without contacting the hooks. The hooks project from the drum via openings in the circumferential surface of the drum and are retractable into a circumferential surface of the drum. A method for separating plastic film material from waste is also described.

  • Patent number: 7690402
    Abstract: For tying wire material around a bale, a pair of end portions of the loop is held in a substantially mutually parallel orientation. An engaged section of at least one of the end portions is moved about a longitudinal axis of the other end portion of that pair, such that the pair of end portions is twisted into a wire twist between an engagement area and a portion of the loop extending about the bale. During twisting, wire material of at least one of the end portions slips through the engagement area towards the portion of the loop extending about the bale. An implement and twisters for use in such a method are also described.

  • Publication number: 20070208455
    Abstract: For sorting items out of waste material, a system is provided including a conveyor for transporting waste material, a detector for identifying and locating items of the waste material on the conveyor, at least one depositing area along the conveyor, at least one robot along the conveyor; and a control circuitry communicating with the detector and with the robots. The control circuitry is arranged for controlling the robot or at least one of the robots to pick-up located items of the waste material on the conveyor and to deposit picked-up items at the at least one depositing area. A method for sorting items out of waste material is also disclosed.
