    摘要: A method for manufacturing a multilayer hose having reduced permeation of hydrocarbon fuel vapor, wherein the multilayer hose is useful as a hydrocarbon fuel transport hose, comprises the steps of: extruding a first fluoroelastomeric tubular structure having an inner surface and an outer surface; applying an adhesive on the outer surface of the first fluoroelastomeric tubular structure, wherein the adhesive is applied to the outer surface of the first fluoroelastomeric tubular structure using piezo electric technology comprising a piezo element disposed in an adhesive reservoir positioned at an exit end of an extruder for extruding the first fluoroelastomeric tubular structure. The adhesive reservoir comprising a plurality of nozzles equally spaced apart around the exit end of the extruder through which adhesive is discharged onto the surface of the first fluoroelastomeric tubular structure in a precise and uniform manner as the first fluoroelastomeric tubular structure exits the end of the extruder, the discharge of the adhesive being activated by application of an electric current applied to the piezo element causing the piezo element to rapidly oscillate in a precise and uniform manner causing the adhesive to be repeatedly discharged through the plurality of nozzles in a pulsating manner, whereby the adhesive is uniformly applied to the outer surface of the first fluoroelastomeric tubular structure; and extruding a second fluoroplastic tubular structure onto the first fluoroelastomeric tubular structure such that the adhesive is disposed between the first fluoroelastomeric tubular structure and the second fluoroplastic tubular structure.
