Abstract
An inner tube for a pneumatic tyre is made by a process which includes the step of cutting a length of tubing, the ends of which length lie at an angle with the transverse section of the rubber tubing. The ends are then pressed together in a heated condition to form a splice and the thus-formed tube is vulcanized.
