PURPOSE:To improve the efficiency of an adaptive control line by a system wherein a line for adjusting the ends of a steel pipe and the like consists of a transverse feed attachment in which the feed pitch is changeable in several stages, a plurality of versatile processors and testers. CONSTITUTION:A steel pipe sent from a conveyer 2 in an axial direction is cut by a cutter 1 in a predetermined length and then sent to a pipe end adjusting line. Transverse feed attachments 5a, 5b capable of changing over the feed pitch into three stages of 1-3 pitch are installed between buffer tables 4a, 4b, 4c. Corresponding to the maximum feed number 3, a set of three versatile pipe end processors 7a, 7b, versatile testers 8a, 8b are arranged on the both sides. In a full operational state, the maximum adjusting processing is carried out by setting the feed pitch to 3, whereas the processing is conducted with the adapted pitch number even when one of the versatile machines is stopped because of trouble. Therefore, the operation of the line will not be suspended. |
