ABSTRACT:
A method and apparatus for winding a fiber reinforced resin bell on the end of a pipe. The apparatus includes a pair of parallel conveyor lines with each line having a series of corresponding stations and the pipes on each line are moved or indexed progressively through the stations. Corresponding stations in each conveyor line are winding stations, and as each pipe is indexed to the winding station, it is moved axially toward the opposite conveyor line. The pipe is rotated about its axis and a resin impregnated fibrous band is wound around an insert projecting from the end of the pipe to form the bell. As the band is being wound, a second pipe from the winding station of the other conveyor is moved axially to position the end of the second pipe in proximate abutting relation to the end of the first pipe being wound. After the winding operation has been completed on the first pipe, the band is transferred to the adjacent end of the second pipe and the band is severed. As the band is wound on the second pipe to form the bell, the first pipe is moved back to the conveyor line and another pipe is indexed to the winding station and moved axially inward to position the pipe end adjacent the end of the pipe being wound.
