ABSTRACT:
This invention is a vacuum bagging device which consists of a receiving bag separated from the product to be conditioned by a flexible and deformable spout. This spout is electropneumatically operated. The receiving bag is made of a material which can be thermo welded. It receives under vacuum the product to be conditioned which remains in this state until the welding operation takes place, the latter being achieved by thermocompression of the upper part of the bag. The operations are synchronized by a programming electromechanical circuit. This invention can be used for fast conditioning and bagging of powdery, granulated or pulverized products, whatever their quantity.
