Abstract

The row of dies is sepd. by drawing drums driven by individual electric motors. The motor speeds are adjusted to allow for the stepwise increase in drawing speed as the tube da. reduces while maintaining a prescribed back tension on the tube at the inlet to each die. The dies are preceded by a plant which rolls flat strip into tube and welds the seam; the tube then travel horizontally through a row of dies apart from being wound on the drawing drums, and tension is also exerted by driven rolls pulling the tube through the plant. Each die is provided with an inlet tube for hydrodynamic lubrication using a lubricant fed at is not >100 atmos. and each die, die-holder and inlet tube are cooled by circulating water. The dies are pref. slowly rotated during drawing. High prodn. speeds using constant back tension in each drawing stage; and the special tube lubrication devices permit a large redn. in tube cross-section in each die.
