Siping is a process of cutting thin slits across a rubber surface to improve traction in wet or icy conditions. Siping was invented and patented in 1923 under the name of John F. Sipe. [1] [2] The story told on various websites is that, in the 1920s, Sipe worked in a slaughterhouse and grew tired of slipping on the wet floors.

Rubber pad forming process, 1: bottom of the press. 2: lower die. 3: sheet metal. 4: rubber pad. 5: top of the press. Rubber pad forming (RPF) is a metalworking process where sheet metal is pressed between a die and a rubber block, made of polyurethane. Under pressure, the rubber and sheet metal are driven into the die and conform to its shape ...
The first commercial use of siping was a year earlier, where Tecalemit used a knife-cutting process almost identical to Sipe's original patent as a means of recutting worn treads.

Curing is the process of applying pressure to the green tire in a mold in order to give it its final shape and applying heat energy to stimulate the chemical reaction between the rubber and other materials. In this process the green tire is automatically transferred onto the lower mold bead seat, a rubber bladder is inserted into the green tire ...
