  • Patent number: 10967418
    Abstract: A forming device, (e.g., a spindle press), can include a processing head, having a processing tool that is guided along a movement axis for the forming processing of a workpiece, and a processing region, located opposite the processing head, a processing station configured for the forming processing of the workpiece, and a rotary table having an axis of rotation parallel to the direction of movement and workpiece receptacles that are arranged, with respect to the axis of rotation, in an offset manner with respect to one another in the circumferential direction. The rotary table is configured such that each of the workpiece receptacles is transferable into at least one first working position located within the processing region and into at least one, second working position at least partially laterally outside a cross-sectional area of the processing head in axial projection with respect to the axis of movement.

  • Patent number: 7010952
    Abstract: A device for holding at least one roller of a rolling machine that can rotate about a rotational axis includes two holding arrangements that can be arranged on opposite faces of the roller viewed in the direction of the rotational axis. The device further includes at least two coupling parts each configured for a coupled mode and an uncoupled mode. A first of the two coupling parts has at least one, preferably essentially straight first groove, and has a second groove that does not run parallel to the first groove. A second of the two coupling parts includes a first coupling element and a second coupling element, wherein the first coupling element projects further outward from the second coupling part than the second coupling element. In at least one implementation, the roller can be detached or removed from the holding arrangements when the holding arrangements are in uncoupled mode.
