Abstract

PURPOSE: To surely feed the prescribed amount of material, to increase the feed rate, and to improve the efficiency of the pipe forming process, by temporarily releasing the material between the forward rolling pass and the backward rolling pass, by giving a circumferential rotation to this released material in order to change the direction of the rolling force.
CONSTITUTION: The shapes of calibers of rolling rolls 4, 4 are made different, and an idling pass is inserted between the forward rolling pass and the backward rolling pass. An idling zone for giving a clearance to the material is formed in a range from the front of the withdrawing point to the withdrawing point in the calibers of rolling rolls 4, 4. Hereby, even in the case that the rolling stand 5 turns back from the end of withdrawal B, the material 2 is released from the restraint of the rolling rolls 4, 4 and is placed under a freely rotatable condition. For the purpose of giving a rotation to the material 2, an acting part is arranged in the material turning cam 31, the screw shaft 32 is pushed out at the same time as the second idling pass starts during the forward rolling pass is performed, and the material 11 is rotated together with the mandrel 16.
