ABSTRACT:
A press for packing loose compressible material, such as tobacco, into rectangular cases or cylindrical hogsheads. The press includes a charger for delivering the material into the container and a pressing ram movable through the charger to pack the material into the container. The bottom of the charger, which is receivable in the container, comprises a double-walled sleeve, the inner wall being perforated and the outer wall being imperforated. An air conducting channel is defined between the walls which communicates with a manifold at the top of the sleeve. This manifold is connected to a pump to draw air out of the sleeve, up the channel and into the manifold. Use of the sleeve creates a negative pressure in the sleeve so that atmospheric pressure, exerted on the top of the loose material in the charger, will reduce the height of the material in the charger and thus allows use of shorter chargers, rams and cycle times, as well as reducing dust. The charger can have an additional double-walled section above the bottom sleeve to provide further reduction in the height of the loose material.
