摘要： A device for producing a loop at the end of a coil spring has a gripping unit with gripper jaws for retaining the spring in a processing position. The gripping unit is movable to and from the processing position and at least one section of an end turn of the spring protrudes over the gripper jaws. A first slewing gear unit has an output shaft and a coupling section for detachable coupling of a tool for the forming of a loop on the spring through upward bending of the end turn section protruding over the gripper jaws. A counter block attached laterally to the travel direction of the gripping unit is movable over the section of the end turn of the spring protruding over the gripper jaws and has a bending edge as a bending form for producing a loop with the tool.

摘要： Methods and apparatus for forming devices including dead-ends and insulator ties from flat and other strips of material, as well as the devices themselves, are disclosed. Components of these devices may be formed continuously from a single strip, avoiding the need to weld or clamp the components together. Forming the devices in this manner reduces the possibility of stresses or non-uniformities forming when the components are joined and permits continuous automatic or semiautomatic manufacture to occur.
