  • Patent number: 8465618
    Abstract: A process for recovering rubber from a tire, the tire including a rubber tread block, steel belting, and an inner liner that serves to hold the air pressure in the tire. The bead and sidewall may be removed from the tire leaving a loop of tread material. Next, the loop is placed on a rubber-separating machine to hold the loop in place. One or more cutting blades are lowered into position at the tread portion of the tire. Once the blades are in place, the tread loop is placed in motion around the rollers. As the blades contact the steel belts, the cutting blades separate the tread rubber from the reinforced rubber at the interface between the tread rubber and the steel belts.

  • Publication number: 20110023668
    Abstract: A process for recovering rubber from a tire, the tire including a rubber tread block, a reinforced portion below the tread block portion, typically known as steel belting, and an inner liner that serves to hold the air pressure in the tire. The bead and sidewall are removed from the tire leaving a loop of tread material. Next, the loop is placed on several rollers of a rubber-separating machine to hold the loop in place. One or more cutting blades, preferably chisels, are positioned at the tread portion of the tire. The cutting blades are lowered into position. Access to the steel belting can be accomplished by making an initial cut through tread block to expose the steel belting. Once the blades are in place, the tread loop is placed in motion around the rollers. As the blades contact the steel belts, the cutting blades separate the tread rubber from the reinforced rubber at the interface between the tread rubber and the steel belts.
