Abstract: PURPOSE:To prevent malfunction by disposing a magnetic proximity switch right above the axis of a pressing roller pushed up by a passing tubular body with a suitable clearance up to the roller, measuring the thickness of a fixed part of a tubular body and outputting an identifying signal when the measured thickness is above the thickness of one tubular body. CONSTITUTION:When tubular bodies 1 are normally fed out one by one, the tubular body 1 is pressed by a feed click 4, and put on a chain 2 to be passed between a support roller 5 and a pressing roller 6. At that time, the pressing roller 6 is pushed up for the thickness(t) of one tubular body 1. At this time, the push-up amount changes with a plated part of a ribbed tubular body 1, the central part of a non-ribbed part and a ribbed part, and the clearance (d) between the axis 7 of the pressing roller 6 and a magnetic proximity switch 8 also changes for the change amount. The standard thickness during normal operation is taken as the change amount, the change of change amount is compared, and when abnormality is determined, an identifying signal is output. For example, when it exceeds 1.5 times as large as the standard thickness, an identifying signal is output.
