  • Patent number: 7716900
    Abstract: A method for strapping a package with a strapping machine that includes a motor drive having a drive shaft that rotates 360° within a strapping cycle and controls work components including at least one clamping device for the strap to be strapped. The clamping of the leading strap end, fed in in a strap guide frame, for the strap to be strapped in the subsequent strapping cycle occurs in the current strapping cycle in the time between the beginning of the removal of the package already strapped in the current strapping cycle and the end of the addition of a new package to be strapped, whereupon the drive stops. After the conclusion of the tensioning process for the fed-in strap about the package, for performing the strapping process, the drive rotates continuously 360° without an intermediate stop in the new strapping cycle until the new leading strap end has been clamped.

  • Patent number: 7412815
    Abstract: A welding head for a strap binding machine includes a strap guide element that can be moved into and out of a strap guide path, a welding device that can be moved into and out of the strap guide path and that is for fusing strap segments of overlapping strap ends that are to be welded, and a pressing device for pressing the fused strap segments against a pressure part, the strap guide element and the welding device being pivotably borne and both being directly or indirectly motion-coupled to the longitudinally movable pressing device such that they can be moved into and out of the strap guide path depending on the movement of the pressing device.

  • Patent number: 7357289
    Abstract: Welding head for a strap binding machine includes a strap fixing device for fixing the overlapping strap ends that are to be welded to one another, a welding device for fusing the strap segments that are to be welded, and a pressing device for pressing the fused strap segments against a pressure part, whereby the strap fixing means are embodied as two separate, pivotably borne clamping jaws that are motion-coupled to the longitudinally movable pressing device such that they can be caused to engage and disengage with the binding strap depending on the movement of the pressing device.

  • Patent number: 7318308
    Abstract: Device for strapping, especially for longitudinally strapping packaged material with strapping, comprising a strap roll, from which the strapping, which is to be processed, is pulled with formation of a strap storage system for a subsequent strapping process. A movable strap carrier is provided for pulling off the strapping and can be moved from a first position into a second position, taking along the strapping, while the strapping is arrested at a place, downstream from the strap carrier with the aid of holding means.

  • Patent number: 5757389
    Abstract: A printing device for objects, which are continuously moved forward, in particular for parcels, wrapped magazine piles or the like, comprises a transport path, alongside of which the objects can be transported at a defined rate of feed. By means of an adjustable matrix printing head the surface to be printed of the objects can be printed in contactless manner when they pass the printing head. A scanning member, related to the transport direction of the objects, is arranged at a distance before the printing head. The scanning member scans the position of the surface to be printed of the objects and tracks the printing head according to the position of the surface to be printed of the objects by a corresponding control of an adjustment drive of the printing head.

  • Patent number: 5575379
    Abstract: A newspaper conveyor has an endless conveyor chain (1) running along a conveyor (3) with a plurality of newspaper grips (7) in rows. Their movable clamp (11) may be set in two opening positions, a first one in which the movable clamp (11) is held open against the closing force of a spring (20) by a cam control curve (28) and a second in which the movable clamp (11) is self-lockingly held open by friction by the leaf spring (20).

  • Patent number: 5078058
    Abstract: A tensioning device for a packaging tape, which is slung around a stack of goods in a packaging station and of which the free end is held there, has a driving plate drivable by a motor around an axis of rotation with a bearing surface for the tape. Clamping elements each having a clamping surface are associated with the driving plate. At least one guiding element is provided for the clamping elements, by means of which, in a closing area smaller than the surrounding angle of the tape around the bearing surface, the clamping elements can be brought into a position, in which the tape is non-positively held between the clamping surfaces and the bearing surface.
