Abstract
A bicycle tire, notably tubular tire, includes a flexible reinforcing structure added to the tread, the reinforcing structure consisting of high tensile strength yarns assembled beforehand in the form of a knitted sheath or tubular member, and intimately bonded to the rubber by causing the rubber to penetrate into the open meshes of the reinforcing structure during the tire vulcanization.
Claims7
A puncture resistant cycle tire comprising:
- a cycle tire casing having attached thereto a tread;
- a penetration resistant puncture preventing structure means positioned between said tread and casing, said puncture preventing structure means comprising a prefabricated assembly of high tensile strength threads in the form of an open mesh knitted sheath or tubular member, said sheath or tubular member having a transverse cross section, along a plane extending axially of said tire, in the form of a completely enclosed and endless configuration;
- and
- said tire being vulcanized such that rubber from at least one of said casing and said tread penetrates into the open meshes of said puncture preventing structure means, thereby intimately bonding said puncture preventing structure means to said rubber.
