Abstract

Tool carriers are arranged, together with an operating pump and reversing and stopping devices, in a closed hydraulic circuit, and have end switches. The end switches, on which the tool carrier first passes at the end of its movement, are connected to a magnetic control valve stopping the operating pump. Those end switches, on which the tool carrier finally passes, are connected to a magnetic control valve which locks a coupling valve. The first magnetic control valve is also connected to the coupling valve effecting disengagement by a branched pipe. The branch has an initial pressure valve parallel to a back pressure valve. The direction of flow through the initial pressure valve corresponds to that of the branched pipe, and the initial pressure valve is connected to the operating pump control device to effect the operation position.
