Abstract:
1. An apparatus for wrapping material onto and around a pipe, the apparatus comprising a shaft, the shaft rotatable by a driving apparatus, a payout core containing material to be wrapped onto a pipe, the payout core releasably mounted on the shaft, a deflection arm assembly secured to the shaft for rotation by the shaft, rotation of the shaft rotating the deflection arm assembly with respect to the payout core so that the deflection arm assembly takes material from the payout core and wraps the material onto a pipe adjacent the deflection arm assembly, each of the shaft and deflection arm assembly having a central opening through which is movable the pipe as the pipe is being wrapped, a rewind core releasably mounted on the shaft, the rewind core having material thereon for wrapping around the pipe, the rewind core positioned adjacent the payout core, the rewind core movable into a position of the payout core following emptying of the payout core of material for wrapping so that the rewind core becomes a new payout core, wherein the rewind core is located on the shaft for rewinding on the rewind core material for wrapping onto the pipe, wherein the deflection arm assembly is located for applying material to the pipe at a desired wind angle, wherein the payout core includes two halves releasably connectible together around the shaft, wherein the rewind core includes two halves releasably connectible together around the shaft, roller apparatus on the deflection arm assembly for facilitating payout of material from the payout core to the deflection arm assembly, and the roller apparatus including a plurality of spaced-apart rollers positioned for moving the material onto the pipe at a wind angle.
