ABSTRACT:
A bag breaking apparatus has an apron feeder type conveyor with an apron constructed of over-lapping pans. Thin upstanding triangular teeth are mounted to each pan parallel to the direction of motion of the conveyor. Bags of trash are supplied to the conveyor and progress to an outfeed end. A roll is positioned over the conveyor near the outfeed end. The roll is driven about the axis of the roll. Triangular teeth mounted to the roll interdigitate with the teeth on the conveyor thus rending the bags which pass between the roll and the conveyor. The roll can be raised and lowered to accommodate bags of different sizes and is pivotable to swing upwardly when faced with oversize or excessive amounts of trash and thereby allow the material causing the jam to pass under the roll and off the outfeed end of the conveyor.
