<p>A hose, particularly a vehicle exhaust hose, comprising an inner, thin rubber-coated fabric and an outer helically-shaped reinforcement which functions to maintain the intended cross-sectional shape of the hose and which is adhered to the surface of the rubber-coated fabric. The hose is characterized in that the helically-shaped reinforcement has an inner core of plastic material having a predetermined, relatively high melting point, and at least one layer outside the core, this layer being made of a similar plastic material. The layer which lies nearest the outer surface of the core is bonded adhesively thereto, and any further layers that may be included are bonded adhesively to one another in a similar fashion. The outer layer is comprised of a plastic material whose melting point is lower than or equal to the melting point of at least the nearest lying layer or the core, whichever is applicable. The contact region between the rubber-coated fabric and the plastic helix has an adhesion facilitating structure with intimate contact between the plastic helix and the rubber-coated fabric and a partially melted outer plastic layer. The invention also relates to a method for producing the hose.</p> |
