  • Manufacturing of inner tubes for tires
    Patent number: 4095638
    Abstract: Self-curing elastomeric compounds in liquid suspension are sprayed onto a warmed rotating former having preferably a form developed from the radial dimensions of the inner tube to be made. The tube is cured and complete on the form by transposing one end of the sleeve to the opposite axial end of the former where the one end is seamed to the other end of the sleeve. Both the process and the tube produced by the process have advantages in manufacturing cost, in material saving, and at least equal quality performance relative to conventional inner tubes and methods of making them.
