A method is described for curing an elastomeric tubular article having a thermoplastic jacket thereon. The curing is achieved either by heat or by microwave radiation. After curing, the thermoplastic jacket is removed.

Vulcanization of hose composites protected with thermoplastic jackets

The vulcanizing of elastomeric articles by captively securing the article to be cured under pressure by a mold that is transparent to microwave energy. The mold in the preferred embodiment is a pair of conveying runs which define cooperatively a mold cavity therebetween. The microwave transmitting devices are located along the path of movement of such conveying runs.

Method and apparatus for vulcanizing hose

An apparatus for continuously vulcanizing elastomeric hose employing a tubular, helically extending vulcanizing chamber with an entrance for unvulcanized hose at one end and an exit for vulcanized hose at the other end terminating in a fluid bath which collects the vulcanizing fluid for re-circulation. Means are provided to circulate a vulcanizing fluid at elevated temperatures and pressures through the chamber to transport the hose therethrough while providing the heat and pressure required for satisfactory vulcanization. The fluid bath provides means for effectively preventing escape of pressurized fluid contained in the system.

Apparatus for vulcanizing hose

An apparatus adapted for continuously vulcanizing elastomeric hose comprises a tubular, helically extending vulcanizing chamber with an entrance for unvulcanized hose at one end and an exit for vulcanized hose at the other end. Means are provided to circulate fluid at elevated temperatures and pressures through the chamber thereby transporting the hose therethrough while simultaneously providing the heat and pressure required for satisfactory vulcanization. Special sealing means are provided to permit the flaccid hose structure continuous entry to the chamber while effectively preventing escape of pressurized fluid contained therein.

Limp, elastomeric hose is fed through a pressurized chamber having an inlet and an outlet opening, the outlet opening leading directly to a pressurized hose treatment zone. Seals at both the inlet and outlet opening of the chamber simultaneously permit continuous passage of hose and prevent escape of the pressurizing fluid from the chamber and from the treatment zone. The hose is driven from the inlet end of the chamber up to and out of the outlet seal of the chamber, and into the treatment zone by a pair of vertically spaced substantially mutually parallel, endless, flexible belts disposed within the chamber.
