A working jig is described. It has a number of hydraulically controlled set elements (6-11) with inlets for hydraulic fluid under pressure. The working jig is especially characterized in that it has a plane side which is provided with a number of elongated first cavities (19-29). A cover (31) is provided to form, tightening the upper side of the cavities such that channels are formed leading to the inlets for hydraulic fluid, fed by a connection (30) between a pressure source and the channels. |
