Cable processing equipment for removing a screening film from a screened multi-core round cable includes four knives radially movable relative to the cable for cutting into the screening film. In that case, each knife is associated with a cable core of the round cable. The knives have concavely formed cutting edges and guide elements, which guide elements have guide sections in which the cable cores encased by the screening film are receivable. The knives protrude relative to the guide elements in the region of the guide sections by a projection length. The guide sections have a concave circularly cylindrical shape and form a concave abutment surface for the cable cores.

In a method of removing a protecting synthetic coating (1) from an elongated element (2) in the form of an optical fibre (3) surrounded by the coating a cut (8) is created into the coating by knife edges (6). The element is displaced with respect to the knife edges in the longitudinal direction of the element for displacing coating material (17) by said knives. At least one drop of liquid (12) with wetting properties is supplied to the cut for being sucked into a space created between the coating and the optical fibre during said displacement for acting as a lubricant for a sliding of the coating to be removed along the fibre.

Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a cable preparation device configured to cut one or more layers of an electrical cable and a computing device configured to control the cable preparation device to cut the one or more layers of the electrical cable. The computing device may determine one or more target cutting distances and determine whether an actual cutting distance satisfies the target cutting distance. The computing device may detect defects in the electrical cable. The computing device may further determine whether the cable preparation device should be serviced.

A method is for producing a cable which comprises a conductor and a barrel. The conductor has individual wires and is enclosed, at least in portions, by a piece of insulation. The conductor is heated and a crimping process is carried out for electrically contacting the barrel with the conductor. The barrel is pressed together with the heated conductor during the crimping process in such a way that the conductor is initially compressed on a first axial sub-portion of the conductor and subsequently the compression of the conductor is spread to a larger second axial sub-portion.

A stripping apparatus and a stripping station capable of reducing cycle time for steps of stripping an insulation coating from a conducting wire material are provided. A stripping apparatus configured to strip an insulation coating WL from a conducting wire material W, including the insulation coating WL and cross-section of which orthogonal to a longitudinal direction has a rectangular shape, the stripping apparatus includes: an upper mold 150 provided with a stripping blade configured to strip the insulation coating WL; a lower mold 110 configured to support the conducting wire material W from a lower side thereof; a pressing member 130 configured to prevent displacement of the conducting wire material W; and a rotation mechanism configured to rotate the conducting wire material W around a rotational axis C1 that is parallel to a axial center of the conducting wire material W.

A stripping apparatus and a stripping station capable of reducing cycle time for steps of stripping an insulation coating from a conducting wire material are provided. A stripping apparatus configured to strip a film WL off a long workpiece W of which outer periphery is coated with the film WL, includes: a cutting blade configured to move up and down in a direction orthogonal to an axial direction of the workpiece W; an upper mold having the cutting blade; a lower mold supporting the workpiece W; and a workpiece rotation mechanism configured to rotate the workpiece W by a predetermined angle around a rotational axis C1 parallel to an axial center of the workpiece W in synchronization with an upward movement and/or a downward movement of the upper mold.

In a method of removing a protecting synthetic coating (1) from an elongated element (2), the elongated element (2) including an optical fiber (3) surrounded by the coating, a cut (8) is created into the coating by knife edges (6). The element (2) is displaced with respect to the knife edges in a longitudinal direction of the element (2) for displacing coating material (17) by the knives. At least one drop of liquid (12) with wetting properties is supplied to the cut for being sucked into a space created between the coating and the optical fiber during the displacement of the coating for acting as a lubricant for a sliding of the coating to be removed along the fiber.

An arrangement for assembling cables having cable processing devices arranged in parallel adjacent to one another wherein each cable processing device includes processing stations for processing cable ends of a cable, a cable conveying device running along a longitudinal machine axis for transporting the cable to at least one of the processing stations in the direction of the longitudinal machine axis, and a central control unit for operating the cable processing device which is arranged to a side of the cable processing device with respect to the longitudinal machine axis. The cable processing devices are arranged in at least one group with two adjacent cable processing devices, wherein due to a mirror-image configuration the central control units and the cable transport control units of the two adjacent cable processing devices forming the group are arranged facing and opposite one another to increase efficiency and ergonomics for an operator.

Determining at least one stripping parameter for stripping a cable containing a conductor by: a) cutting an insulation up to a cutting depth of a cable with at least one stripping knife, wherein an initial cutting depth is selected to be the cutting depth, which ensures that the at least one stripping knife comes in contact with the conductor; b) stripping the cut insulation by moving the at least one stripping knife in a longitudinal direction in relation to the cable; c) determining by a detecting unit whether the at least one stripping knife has come in contact with the conductor in the step a); and d) repeating the steps a) to c), wherein in each case the cutting depth is reduced by a cutting feed value until a conductor contact can no longer be determined, whereby the stripping cutting depth is maintained in a parameter determination phase.

Each of cutting mechanisms of a device for forming a notch for stripping includes: a stopper which is capable of approaching and/or being separated away from an outer circumferential surface of a coated electric wire; a biasing part biasing the stopper; a cutter blade; a stopper movement mechanism configured to, when forming a notch, move the stopper together with the cutter blade to bring the stopper into contact with the outer circumferential surface; and a cutter movement mechanism configured to, after bringing the stopper into contact with the outer circumferential surface, forward the cutter blade to a position corresponding to a specified notch depth for forming the notch.
