  • Patent number: 8234772
    Abstract: A continuous cable processing apparatus for producing cable sections with processed ends comprises a cable transport apparatus having at least one transporter for moving and holding the cable in the axial direction and, transversely thereto, a processing station. According to a special variant, two transporters are arranged in the longitudinal cable direction on both sides of the processing station and, after the cable has been cut through, each hold one of the cable end regions produced on cutting, so that the end regions are movable in the longitudinal cable direction. At least one of these end processing stations is arranged transversely with respect to the longitudinal cable direction, adjacent to the processing station and at least one transporter is movable transversely with respect to the longitudinal cable direction so that a cable end region can be fed to the end processing station.

  • Patent number: 5438753
    Abstract: The invention relates to a process and an apparatus for cutting through a cable sheathing of fibres, in particular Kevlar (Trademark) fibres. A cutting apparatus has several, preferably concentric, cutting zones along the circumference of the cable, for example defined by a cutting die and an anvil, the cutting die and anvil preferably having a lateral recess for lateral insertion of a cable, and being pressed and/or hammered against one another in such a way that the fibres which are held in between are cut. An air stream in a suction pipe ensures the positioning of the fibres between the cutting die and the anvil. The invention permits rapid and reliable cutting of sheathing fibres.

  • Patent number: 5361384
    Abstract: The invention relates to a stripping apparatus for fibre-optical cables (31), having rotatable stripping knives (1033) and rigid centering jaws (1040) which, in the operating position, are arranged between the stripping knives and the end of the cable (31). The centering jaws (1040) are furthermore located in the immediate vicinity of the stripping knives (1033) and hold the cable (31) to be stripped, in such a way that any torques acting on the cable (31) are absorbed and twisting or breakage of the cable (31) is avoided. Furthermore, modifications of the stripping machines are described which disclose the lateral insertion of a cable (31) into the particular stripping position inside a stripping station (1,2,3) by means of a manipulator (35), a novel stripping station (3) for stripping coating layers for optical waveguides and a novel conductor stop apparatus (80) and a drive-saving arrangement of several stripping stations (1,2,3) on a carriage (912).

  • Patent number: 5243882
    Abstract: A device for the mechanical stripping of at least two layers of electrical or optical cables has a stop for a fed-in conductor. The conductor is fixed in position by clamping jaws, whereupon its insulation can be severed by at least one rotating stripping blade. Disposed immediately next to each blade is a centering jaw, which centers the conductor. The jaw is radially movable relative to the blade so as to permit the penetration of the blade into the layer of insulation. The blades and the centering jaws are positioned axially and the desired cutting depth of each of at least two stripping operations is adjusted by spindles, each of which is operated by a motor which is controlled by a digital controller.

  • Patent number: 5010797
    Abstract: The invention relates to an arrangement of a plurality of holding, centering or knife jaws (7, 18) for cutting and/or stripping apparatuses for rod-like or cable-like articles (22). The jaws (7, 18) are each displaceable or pivotable in a certain direction. The end points of a line (5) which, when the jaw (7, 18) is viewed, is turned to face the article (22) define a straight line (2). The angle between the particular direction of each jaw (7, 18) and this straight line (2) is less than 90 degrees. This results in constantly changing contact points for changing diameters of the articles (22), and distributed wear of the jaws (7, 18).

  • Patent number: 4027557
    Abstract: A stripping device for wire, or the like: a spindle is freely rotatably mounted inside a housing; appropriate threaded connections between the spindle and the interior of the housing cause the spindle to rotate axially when the spindle is pulled; an insulating cutting knife is operatively connected with the spindle to rotate therewith; a passage leads past the cutting edge of the knife; the knife is pivotable out of the passage to permit the wire to be inserted into the passage and then the knife returns to the cutting position after insertion of the wire; pulling upon the wire pulls the spindle, causes the spindle to spin and rotates the knife around the insulation layer.
