ABSTRACT:
A method and apparatus is provided for manufacturing a reinforced elastomeric hose. Other reinforced hoses are prepared in individual stations for particular parts of the reinforced hose consequently requiring large amounts of manufacturing floor space. Still other hoses that are made while utilizing small amounts of floor space do not provide a high strength braided reinforcement member. A reinforced hose (10) is produced by continuously braiding a tubular reinforcement member (16) on a mandrel (50), progressively removing the reinforcement member from the mandrel (50), and at approximately the same axial location extruding a liner (26) and cover (28) onto the reinforcement member (16) adjacent the mandrel (50). After leaving the extruders (33,34), the formed hose (10) is pulled at a linear rate faster than the hose (10) is being produced in order to change the braid angle of the braided reinforcement member (16) to a predetermined smaller braid angle. As the hose (10) leaves the extruders (33,34), it is pulled through a curing mechanism (30) to cure the hose (10) while the braid angle is at the predetermined angle. Upon release and cooling of the hose, the hose rebounds to an optimum braid angle of approximately 54.degree. 44'. The braided reinforcement member (16) provides the high strength characteristics while the extruding of the liner (26) and cover (28) at approximately the same axial location near the braiding mandrel (50) minimizes the manufacturing floor space and reduce cost.
