摘要： An automatic formation device or an automatic formation system sets an equipment operation time from a required manufacturing time per product during the manufacturing of tubes having a round, polygonal, or oblong cross-section, wherein values are calculated from a product diameter (D), and a pitch (P), a product length (L) and a preset time (T) of a metal band plate to be wound, operations of respective components are controlled on the basis of the calculated values while the respective values are being controlled, and the metal band plate is held by a chuck that is disposed on the tip side of a winding core member and rotates in a synchronized manner so as to prevent loosening of the wound metal band plate by tightening/untightening the metal band plate as needed. Also, a rotation speed correction function for a motor system is added.

摘要： The present invention provides a method and an apparatus for manufacturing an interlocking pipe obtained by easily and precisely shaping a pipe with a circular cross section or with the edges of the cross section nearly forming a circle in a non-loose manner, so as to provide excellent machining performance when the interlocking pipe is cut off and provide excellent operation efficiency for the apparatus itself. A metal band plate is helically wound onto a core member with a circular cross section or with the edges of the cross section nearly forming a circle. Clamping device is freely assembled at a front end of the code member in a detachable and switchable manner, and synchronously rotate in accordance with instructions from a main computing-controlling member, so as to prevent the metal band plate from being loosened, thereby to manufacture the interlocking pipe efficiently.
