Abstract: A system for finishing conventionally produced clay pipes having plain ends whereby the pipes are successively placed on mandrels which hold the pipes vertically at the bottom thereof on a first urethane table which is indexed successively through a number of stations, for example 60. At one station liquid urethane is poured into a mold formed between the pipe and mandrel to form a urethane collar. The pipes with this collar are successively transferred, to mandrels on one of two identical winding tables which are similarly indexed through a number of stations, for example 20. At a winding station on each winding table strands of fiberglass filaments are helically wound about the lower end of each pipe and the mandrel to form a bell on the pipe end. After curing, the pipes are then removed from the winding tables. Operations of the tables are under the control of a disclosed control circuit.
