102 further includes an opening bin hopper or the like 120 that is in communication with passages 126 the passages 126 lead into nozzle chamber 125 the opening 120 and passages 126 accept material to form the inner layer 14 of the tube assembly 12 the opening 120 is in communication with a source of the material for the inner layer 14 the source is typically in a viscous liquid state as is known in the art as the appropriate material enters the respective opening 118 120 and 122 and flows along the respective passages 124 126 and 128 they meet to form the various layers within the nozzle chamber 124 with one layer deposited upon another layer this material is then extruded from the nozzle opening 110 to form the tri lamina tube assembly 12 in any desirable length air or other injection gas may blown through the nozzle bore 114 introduced through the extrusion chamber 116 the textile reinforcement is then added around the extruded tube assembly after the textile reinforcement is added the tube and textile assembly is fed into a second extrusion machine such as that depicted in fig7 with reference now to fig7 there is depicted an extrusion machine 150 the extrusion machine 150 includes a housing 152 formed from a plurality of components as is known in the art including a die or extrusion head 154 that is bolted to a component of the housing 152 the die.
