Abstract:
1. A mote molding machine for producing motes in a molding cycle, the molding cycle having a compression phase and an extraction phase; the molding machine comprising: a molding chamber defining a molding cavity, the molding chamber having a front end and a rear end opposite the front end; a front plate movable between a first position and a second position, a rear plate located opposite the front plate, the rear plate movable between a third position and a fourth position, a first shifting system for moving the front plate between the first position and the second position using a third electric motor; and a second shifting system for moving the rear plate between the third position and the fourth position; wherein the first shifting system comprises a first electric motor, the third electric motor, and a clutch system, wherein the second shifting system comprises a second electric motor for moving the rear plate in the compression phase and a fourth electric motor for moving the rear plate in the extraction phase, wherein the first electric motor shifts the front plate toward the molding cavity in the compression phase and the second electric motor shifts the rear plate toward the molding cavity in the compression phase, and wherein a speed of movement of the front plate and the rear plate during the compression phase is slower than a speed of movement of the front plate and the rear plate during the extraction phase.
