ABSTRACT:
The invention relates to an improved method and apparatus for tube drawing which relates to the use of a floating plug and die arrangement, the necessary draughting tension in the tube being drawn being generated by a rotatable tube block around which the tubing downstream of the die is wrapped. The invention proposes to mount a tube guide upstream of the die in such wise that the relative spacing between the guide and the die can be a minimum during threading-up of the die but increased during drawing.
