ABSTRACT:
A preformed radiator hose and a method of manufacturing such a hose are disclosed herein. A long length of an uncured hose is first fabricated by alternately wrapping layers of an uncured elastomer and fiber reinforcements around a straight mandrel. The uncured hose is then removed from the straight mandrel and cut into shorter segments. Each of these segments is then placed on a contoured mandrel having a shape corresponding to the intended configuration of the final hose and cured by heating. Although the fully cured hose does have a permanent shape, because of the unique arrangement of the reinforcements, etc., it has sufficient deformability to be easily slipped off the mandrel.
