Abstract (en)
[origin: EP0605067A1] The invention relates to a drawing die holder (6) for a continuous bull block for drawing tubes (4), with a drawing die (8) accommodated in the drawing die holder and with a guide (9), arranged ahead of the said die in the drawing direction, for the centralised feeding of the feed tube into the drawing die. In order to ensure that, on the one hand, the transition zone between the drawing point and the outside diameter of the feed tube slides through the guide without problems and that, nevertheless, the guide encloses the feed tube with sufficient accuracy to ensure that it is fed to the drawing die in an optimum manner, it is proposed that the guide consist of a two-roller set (9) which is calibrated to correspond to the outside diameter of the feed tube (4) and the rollers (10) of which, which are supported in a manner which allows them to rotate freely, can be moved together and apart transversely to their axes by power actuation (11, 12). <IMAGE>
