Abstract

780,939. Rolling tubes. MANNESMANN AKT.-GES. March 12, 1956 [March 16, 1955], No. 7659/56. Class 83 (4). In a rolling mill for seamless tubes the blanks are rolled over a plug 3 by rolls 2 which are separately driven from variable speed motors 10 arranged on opposite sides of the mill stand 1 and coupled to the rolls 2 through Cardan shafts 11. A common control 12 for the motors provides an initial run at slow speed until the rolls have obtained a grip. The work is guided to the rolls over a groove 9 and leaves the mill between guide rolls 6. Support for the tube along the mandrel 4 is provided by a roller table 7.
