Abstract (en)
[origin: EP0230221A2] The preparation bench is mounted on a lifting table (10) and has a receiving tube for receiving the tube (9) to be drawn from a stand-by store (4), or several receiving tubes one above the other which are designed for different die diameters. Before the loading, the lifting table travels up until the tube to be loaded is approximately on the same axis as a new tube to be drawn in the stand-by store. The drawing plug (23) is at the same time advanced slightly. By means of an electronic precision control system, the axes of the plug on the one hand and of the new tube on the other hand are adjusted to be the same. Owing to the fact that the preparation bench contains several receiving tubes having various dimensions, resetting for other die diameters is unnecessary. <IMAGE>
