Patent number: 8234772Abstract: 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.Type: GrantFiled: January 16, 2009Date of Patent: August 7, 2012Assignee: Schleuniger Holding AGInventors: Beat Locher, Jiri Stepan

Patent number: 5438753Abstract: 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.Type: GrantFiled: November 12, 1992Date of Patent: August 8, 1995Inventor: Jiri Stepan

Patent number: 5361384Abstract: 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).Type: GrantFiled: November 12, 1992Date of Patent: November 1, 1994Inventor: Jiri Stepan

Patent number: 5243882Abstract: 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.Type: GrantFiled: October 2, 1991Date of Patent: September 14, 1993Inventor: Jiri Stepan

Patent number: 5010797Abstract: 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).Type: GrantFiled: June 23, 1988Date of Patent: April 30, 1991Inventor: Jiri Stepan
