An impermeable rubber hose is thinned for the purpose of reducing weight and costs. A rigid resin film is used as an intermediate layer. When the resin film is gradually rolled up into a cylindrical shape from a planar shape and fed to an extrusion head and rubber is simultaneously extrusion-molded inside and outside the cylindrical film, the film produces a break or a twist to make extrusion molding difficult. It is an object of the present invention to make simultaneous extrusion molding possible even in such a condition.

To attain the above object, a thermoplastic resin film (5) which forms an intermediate layer (2) and of which the melting point is lower than the vulcanizing temperature is formed in a long belt-shape. Slits (7) are provided at fixed intervals on the right and left long side sections (8, 8) of the film (5) in the longitudinal direction. When the resin film (5) is fed into an extrusion head (10) to be rolled up into a cylindrical shape, because both the long side sections (8, 8) of the film (5) are formed as weak sections by the slits (7), the film (5) adsorbs a strain when bent and is bent in a circle, thereby allowing the right and left long side sections (8, 8) to overlap at an overlapping section (6). In this condition, rubber is simultaneously extrusion-molded inside and outside the film and then, vulcanized to weld the overlapping section (6), thereby eliminating the slits (7).

A faceguard to be mounted on a football helmet which greatly reduces the ability of an opposing player to penetrate the exterior surface of the faceguard and grasp, with his/her hands, the faceguard and rotate the wearer's head in such a way as to cause injury to the wearer's head, neck, or spine. Furthermore, the faceguard will accomplish the above stated while still providing appropriate ventilation for the wearer and allow the wearer to receive water from a standard squeeze type sports water bottle. The faceguard is provided with a flush elastomeric mounting bushing to make the faceguard simpler to manufacture and easier and less awkward to mount to a football helmet. The flush elastomeric mounting bushing provides shock absorption between the faceguard and the helmet at the mounting points. The flush feature of the mounting bushing provides an additional safety benefit of decreasing the likelihood that the mounting will be caught on a player's uniform or cause any puncture or scrape to the skin of another player. The flush feature also makes it difficult for an opposing player to grip or hold the facemask of the wearer. The faceguard is constructed of a single body of injection molded clear or tinted plastic which can withstand high-impact in order to sustain the abuse required of such a device in the game of football.
