ABSTRACT:
Two cooperatively rotating annular wheels are temporarily deformed against each other radially to form a contact length and are partially located in a heated chamber. Each annular wheel is connected to a rotating shaft by means of flexible means. A positive pressure is maintained in the heated chamber. A circumferential groove is provided on the rim of each annular wheel so that when the two annular wheels rotate cooperatively, the grooves cooperate to form a closed orifice along the contact length of the annular wheels. A mandrel, rotating about its axis, protrudes into this orifice. A plurality of elongated composite plies are wound around the mandrel and are clamped and carried forward by the annular wheels. In the heated chamber, the elongated plies are subjected to a sustained pressure and temperature. They are cured under this pressure and temperature after which they are cooled under pressure and exit from between the annular wheels as an elongated cured composite tube.
