  • Patent number: 4499824
    Abstract: Machine for crushing cylindrical aluminium cans for beer, soft drinks etc. The machine comprises a can intake. A craddle for receiving the can in a substantially horizontal position is displacable between a receiving position in the can intake and a crushing position in a press device for squeezing the cans axially between the end walls thereof. The displacement of the craddle between said position is effected by displacement of a closure member for the can intake between opened and closed positions. A perforated sloping plane is arranged below the press device for receiving the crushed can falling down from the press device at the return movement thereof after crushing, and diverting the crushed can to a collecting container.
