摘要：PURPOSE:To prevent the suspension of the internal surface bead cut due to a defective separation by looking at the contents of the number of cut pieces counter and combining the ON-OFF timing of a photocell and the acceleration timing of each pinch roll. CONSTITUTION:Plus 1 is applied by the I/F signal: a cut completion signal ON transmitted from a cutoff device 1, the number of cut completion pieces is stored, and minus 1 is applied by the ON signal of a photocell OMK-PHO 113. Also, the clutches 7, 8 ON-OFF timing is compensated by switching an acceleration timing with the case(long-sized material) when a cut completion signal is transmitted by the ON of PHOI 13 and the case(short-sized material) when a cut completion signal is transmitted by the OFF of PHOI 13, and a surer pipe separation can be executed by awaiting the establishment of a pinch roll 2 rolling reduction force. Thus the internal surface bead cut suspension due to a defective separation is eliminated, the variation of the clutch ON-OFF timing and the rolling reduction force establishment can be offset and the stoppage of a pipe making line can be prevented.
