| 摘要 |
This wire-spiralling machine continuously produces a tubular structure consisting of a spiral winding (2), particularly a pressure-armour layer, from two noninterlocking wires (16) of large cross section delivered from two reels of wire and two locking wires delivered from two reels of locking wire. A motorized rotating circular cage (6) carries the four reels of wire and locking wire at its rear, while the downstream face of the cage (8) supports, on two adjustable--inclination plates (35), two on-board twin-track caterpillars (31, 31') for dragging the wire (16), these caterpillars being arranged just upstream of guide and/or bend rolls (34) leading the wires towards their respective lay point (33).
