A method of producing cylindrical tubular items by drawing and a draw bench relate to methods and devices for plastic working of materials in a cold state. In the course of manufacturing cylindrical tubular items by drawing, said items are subjected to deformation on being drawn through a die and are imparted simultaneously a torsional moment, said torsional moment being imparted to that portion of each item which emerges from the die, while the item portion found in front of the die is restricted from torsion. The draw bench adapted for realizing the method of the invention comprises a device for drawing items through the die, said device being made as a driven carriage, a means for imparting to the item a torsional moment, said means being arranged on said carriage, and a means for restricting the item from torsion arranged at the die entry. Such method and draw bench allow obtaining drawn items featuring sufficient rectilinearity to be transferred to subsequent technological operations without intermediate and final straightening thereof.

A mill is disclosed, said mill comprising a plug head for plugging tubes, one pulling device adapted to draw a tube with a plug through the plug head, a gear for taking tubes off the plug mounted in the rear portion of the pulling device and composed of power cylinders secured on the pulling device at an acute angle to a plane passing through guides of the pulling device with the rods of the power cylinders carrying jaws for gripping the tube being plugged, the jaws being attached to the rods, and two pockets wherein the tubes and plugs are placed after the tubes have been taken off the plugs. The invention is intended for providing a mill featuring an improved production rate with the ensuing augmentation of the production of a drawing mill, and having smaller overall dimensions.
