Abstract: The invention relates to a flexible manufacturing unit with at least two machine tools (1,2) and a transport device (9) movable in rectangular coordinates having receptacles for carriers (8) holding workpieces and for the tools (6). The invention consists in that the transport device (9) is numerically controlled, that the tools (6) are individually transportable between a tool buffer store (29) and the machine tools (1,2) and that tool magazines (5) integrated with the machine tools are provided, which tool magazines are also accessible for tool exchange during the working period of the machine tools (1,2). In this way, a rapid method of operation is possible which is independent of the cycle and permits free selection.

Abstract: Method and device for the partial galvanization of a surface of a conductive material is disclosed. A flow-on channel and a flow-off channel are positioned at an angle relative to the surface at less than 45.degree. and arranged to direct the electrolyte solution at an angle onto the surface to be treated. The electrolyte is removed at an angle to the surface by the flow-off channel such that on the surface to be treated a substantially laminar flow arises. The flow-on channel and flow-off channel are constructed of a corrosion-resistant material. A metallic anode element is arranged in at least one of the flow-on and flow-off channels adjacent the area to be treated.

Abstract: The device bends pipes into a serpentine pipe bank having right-hand and left-hand bends, with the pipe being held, during the bending operation, in a bending rail and the pipe end to be bent being clamped in a bending form. The bending rail and the bending form are mounted in a cylindrical frame which is rotatable about the longitudinal axis of the pipe to be bent. After each formation of two 90.degree. bends, or one 180.degree. bend, the frame is rotated through 180.degree. with the pipe remaining stationary and with the bending rail and bending form completely disengaged from the pipe. The bending rail is adjustable in the frame to fixed positions in accordance with the diameter of the pipe to be bent, and the bending form, together with clamping jaws associated therewith, is pivotally mounted in the frame for swinging about an axis perpendicular to the axis of the pipe.
