Abstract: A linear guide comprising at least two stationarily supported guide bars, on which a guide block is mounted and which is longitudinally displaceable relative to the guide bars. The guide block is provided with a driving unit to generate a relative movement with respect to the guide bars, the driving unit comprising a pinion which meshes with the teeth of a toothed rack extending in parallel with the guide bars. The toothed rack is mounted only at its front and rear ends and is suspended in-between. A guiding element assigned to the pinion is mounted to the guide block so as to be displaceable in the longitudinal direction of the toothed rack on which it is supported in a form-locking manner. The guiding element engages over the toothed rack at the region opposite the mesh between the pinion and the teeth.

Abstract: A bending machine for bending elongated workpieces supplied from a magazine is disclosed. The bending machine comprises a base support; two bending robots arranged on a common guideway centrally mounted to the base support, such that the robots are displaceable parallel to the longitudinal direction of the base support. A holding clamp is positioned on the front face of the base support, with one auxiliary gripper on either side of the holding clamp. The holding clamp is displaceable in parallel with the bending robots. A discharge gripper is positioned on the rear surface of the base support, laterally offset with respect to the holding clamp. All grippers and clamps are pivotable to an inner pivoting position, in which they can hold a workpiece in the working area of the bending machine between both bending robots; and to an outer pivoting position away from the base support.

Abstract: In order to separate rod-shaped bodies from a bundle of bodies, the surface of an uppermost body in the bundle is determined in a separation apparatus by a sensor, which body is then seized laterally of the sensor by a first gripper and is vertically lifted, whereupon a further gripper engages under said body, laterally of the first gripper unit. The further gripper is then moved to the other end region of the body, with the body being lifted out of the bundle. Next, said body is moved to a deposition location by both grippers.
