Abstract
Official abstract text for this publication.
A method of forming a tread comprising two or more layers of rubber is described. The method includes the steps of: extruding a rubber compound through an extruder and a gear pump and mixing with an accelerant and then applying a continuous strip of rubber directly onto a tire building machine to form a first layer of rubber having a first cure rate; adjusting the amount of accelerant to obtain a second cure rate different than said first cure rate, and then applying a strip of rubber having a second cure rate onto the tire building machine, wherein one of the cure rates is faster than the other cure rate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a tread comprising two or more layers of rubber, the method comprising the steps of: extruding a rubber compound through a first extruder and a first gear pump; extruding an accelerant through a second extruder and a second gear pump and then into the first extruder for mixing the rubber compound with the accelerant, and then applying one or more first strips of a rubber mixture having a first cure rate from the output of the first gear pump directly onto a tire building machine; adjusting the amount of accelerant to obtain a second cure rate different than said first cure rate, and then applying one or more second strips of rubber mixture having a second cure rate directly onto the tire building machine, wherein one of the cure rates is faster than the other cure rate.
