ABSTRACT:
An apparatus and method for folding and crushing empty cylindrical cans such that after being folded and crushed the can end faces are essentially coplanar. The apparatus comprises a flat stationary anvil and a flat parallel reciprocable platen defining therebetween a folding compartment into which an empty can is inserted, an independently reciprocable creasing element or plunger slidably inserted in an aperture through the center of the reciprocable platen such as to enter and leave said folding compartment, and a drive arrangement simultaneously advancing the reciprocable platen and reciprocable creasing element into said folding compartment towards the can, the creasing element being advanced more rapidly than or ahead of the platen, and drive retracting the creasing element after the creasing element has nearly passed through the can without stopping the advance of the platen, and subsequently retracting the platen. The can folder may be manually or power-driven and may be equipped with a digital can counter, an indexing feed means, a gravity-fed disposal chute, and a can marking or branding feature.
