Abstract: A pair of tool parts which include a first and a second tool part, can be secured exchangeably in tool jaws of a hand-held tool and can be moved together by means of the tool jaws, for enclosing a cable, encapsulated with an insulating sheath, over a part of a length of the cable. A receiving region of the tool parts formed when moved together, encloses a semi-circular region of the cable in cross section with a longitudinal dimension and a transverse dimension remains for the cable in each tool part. The receiving region is penetrated by a blade and has an inwardly pointing clearance. A plurality of blades are configured in each tool part, and the blade tips run in accordance with a helical line when the tool parts are moved together. Methods for stripping a cable are also provided.

Abstract: A tool head is provided for a hydraulically actuatable tool. The tool head has an essentially C-shaped head body with two C-legs, and a connecting web connecting the C-legs. Each C-leg has a tool carrier for receiving a tool part. The second tool carrier is mounted to be displaceable to the first tool carrier from a first starting position remote from the first tool carrier while traversing a device jaw of the C-shaped head body into a final working position adjacent to the first tool carrier. The connecting web has several through openings lying one behind the other along the longitudinal axis and are separated by a material bracing. The through openings follow an arched shape of the connecting web, and not a line parallel to the longitudinal axis of the tool head.

Abstract: A cutting tool with blade parts having an application surface for a driving force, which essentially extends orthogonal to a cutting plane, is provided. A cutting force acting upon the blade parts causes a counterforce. A line of action of the cutting force extends differently from a line of action of the counterforce. Each application surface has an end facing the cutting plane and an end facing away from the cutting plane. The ends are located on the same side of the cutting plane. In order to reduce a cutting gap between blade edges, the end facing the cutting plane defines a first distance and that the first distance and/or a second distance are chosen such that an intersecting point lies in front of a line of action of the cutting force referred to a clockwise direction.

Abstract: A device is used to sever an electrical power cable for the transmission of high voltage. The device includes a frame having first movable cutting blade carried thereon and second stationary cutting blades carried thereon. The blades can sever the electrical power cable upon movement of the first cutting blade relative to the frame. A sensor is provided and is configured to register a position of the first cutting blade relative to the frame. An evaluation and/or transmission controller is configured to receive information from the sensor and interrupt severing of the electrical power cable by the blades in response to the information.

Abstract: A tool configured to cut a workpiece includes a tool head which has a receiving contour in which the workpiece is received, and a movable cutting edge with a cutting contour. In the course of a cutting process, the cutting edge passes through the receiving contour. The cutting edge is subjected to the effect of an advancement part and can be moved to such an extent in the cutting direction(s) that it can pass all the way through the workpiece. In an embodiment, a position of the cutting edge reached after the cutting edge has passed all the way through the workpiece, the cutting edge, with removal from the advancement part, can be moved out from the cutting direction(s).
