ABSTRACT:
One aspect of the invention is a tire debeading machine (10). A tire is supported on a guide apparatus (15) and raised to an operative position by the action of a support arm (21). A cutting blade (33) is moved against the sidewall of the tire, cutting off the bead. After the initial cut is made, the tire is raised slightly further by the combined action of an initially interlocking vertical arm (75), which extends from said support arm (21), and a roller (71) on an L-shaped arm (69). The further cut by blade (33) is closer to the bead. Another aspect of the invention is a granulating machine which includes three feed rollers (93) (95) (97) which feed the debeaded tires into a cylindrical cutting chamber (106). Inside the cutting chamber (106) are a plurality of rotary cutting blades (127) mounted on mounting plates (130), which cooperate with stationary cutting blades to produce granulated rubber particles and fiber particles. A further aspect of the invention is a separator (180) which includes two separating apparatuses (184) (189), each of which comprise a plurality of sets of revolving plates (185). A flow of air is directed upwardly through the two separating apparatuses, through a rear airflow channel (198) and then out of the separator. The rubber particles drop down through both separating apparatuses and out of the bottom of the machine, while the lighter fiber particles are moved upwardly with the airflow and out the rear of the separator.
