Abstract

PURPOSE: To safely, efficiently carry out the drawing work for the pipe in a short time, by forming the semiconical drawing groove in the sliding surface of each of the driving roller and the following roller.
CONSTITUTION: An end of the pipe W is interposed between the drawing grooves 13a, 13b, formed in the driving roller 9 and the following roller 11; then, the change-over valve is operated to turn round and bring down the following roller 11 in the direction to contact with the driving roller 9. Hereby, the drawing work for the pipe W is started between the drawing grooves 13a, 13b. By turning round the handle 19, the driving roller 9 synchronizes with the following roller 11 through the driving gear 17, idle gears 27a, 27b, and the following gear 21; and two rollers 9, 11, rotate in the mutually opposite directions, and gradually draw the pipe W. Thus almost conically drawn pipe W is cut by cutters 15a, 15b, installed at the terminal ends of the drawing grooves 13a, 13b, to finish the drawing work.
