Patent number: 11749977Abstract: 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.

Patent number: 11684984Abstract: 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).Type: GrantFiled: July 17, 2018Date of Patent: June 27, 2023Assignee: GUSTAV KLAUKE GMBHInventors: Egbert Frenken, Andreas Lehr
