  • the apparatus has a spinning head disposed about the conduit in engagement with the conduit for relative rotating and longitudinal movement with respect to the conduit and for wrapping the wire on the conduit to the predetermined tension and pitch.
  • Wire supply means are either disposed about the conduit in engagement with the conduit for relative rotating and longitudinal movement with respect to the conduit or are mounted on the spinning head, both for supplying the wire to the spinning head.
  • Friction means are associated with the wire supply means to provide a friction drag on the wire supply means thereby preventing uncontrolled payoff of the wire from the wire supply means.
  • Wire tensioning means are mounted on the spinning head and are adapted to receive the wire from the wire supply means at a low first tension to store a plurality of turns of the wire on the wire tensioning means, and to wrap the wire at a higher second tension on the conduit from the predetermined point thereon during the relative rotating and longitudinal movement of the spinning head with respect to the conduit.
  • Drive means are connected to one member of the spinning head and the conduit for causing relative rotating and longitudinal movement of the one member with respect to the other member of the spinning head and conduit.

  • prestressed-steel line pipe two general approaches are open to the manufacturer; the first being a plant-wrapped approach, such as presently employed in the wire-wrapped prestressed-concrete pipe industry, and the second being the field wrapping of pipe just prior to final protective coating and lowering of the pipe into the ditch.
  • a principal inadequacy of the adaptation of the simple tape wrapping machines to the wrapping of prestressed line pipe is the amount of tension that must be imparted to the wire.
  • a tension of approximately 50 pounds is common for tape wrapping, while tensions on the order of about 2000 to 5000 pounds are necessary for the wire wrapping of prestressed pipe to gain the degree of prestress required for the structure. Accordingly, we have found that a-simple redesign of existing tape wrapping machines used for the field coating of line pipe is inadequate for the purpose of wrapping prestressed line pipe.
  • Van Amburgh has no provision for reapplication of torque and his device requires at high speeds and high wire tension impractically high powered drives.
  • the direction of unreeling shown in FIG. 2 of Van Amburgh would result in extremely high reel rotational speeds, which in turn, would require a higher power drive.
  • the tensioning device described in Van Amburgh would not be adequate at high speed, high tension operation because of frictional heating.
