ABSTRACT:
A method is described for fabricating long length hose around an internal moving mandrel comprising the steps of forming an inner tube of an elastomeric or thermoplastic material, curing said inner tube, inserting a lubricated mandrel interiorly a portion of said cured tube, applying a first layer of uncured elastomer or thermoplastic tie gum to said cured tube surrounding said mandrel, encircling the layer of uncured tie gum with a reinforcing material under tension, adding multiple layers of uncured elastomer or thermoplastic tie gum and encircling reinforcing material as necessary for the hose strength required, placing an uncured elastomer or thermoplastic tie gum final layer on said reinforcing material, adding an uncured hose covering material layer on top of said tie gum final layer, wrapping under tension a strengthening material onto the hose covering material for consolidation and protection of the hose during vulcanization, moving the mandrel from the portion of the complete hose to the adjacent portion of the uncompleted hose, repeating the steps of fabricating a length of hose around the mandrel, and repeating the step of moving the mandrel to the next uncompleted portion of the hose until the full length of the inner tube has received all the fabrication materials, then moving the mandrel out of the hose, vulcanizing the uncured hose to cure the hose, and removing the consolidation wrapping from the completed hose.
