    摘要: This invention constitutes an improvement upon the existing practice of manufacturing reinforced automotive heater hose and the like in a continuous operation which comprises continuously extruding an elastomeric tube, continuously applying to the outer surface of the tube an appropriate reinforcing layer of textile yarns or the like, continuously extruding over the reinforcing layer an elastomeric covering layer, and continuously curing the elastomeric components in an elongated chamber containing heat exchange elements the improvement residing in the provision of a method and means for elongating within certain limits the uncured or partially cured hose during the curing process whereby reduction of pressure and temperature within the extruding units and other advantages in production of reinforced automotive heater hose and the like may be realized.
