Abstract

Machine for filling and handling bags, intended to automatically weigh and especially to manipulate a powdery material; comprising a deformable feed duct, an open-end filling tube, attached at one end to the aforementioned duct and intended to be admitted to a container or sack to be filled, of powdery material, and a weighing device intended to receive the weight of the container when full by the action of the filling tube; characterized by comprising a first output regulating device, located on one side of the deformable conduit, and movable from a first position in which the deformable conduit is in the relatively undistorted state, to a second position in which it is partially deformed ; the latter to provide an outlet of small amounts of the powdery material through the conduit; a second output regulating device located on the opposite side of the deformable conduit, and movable from a first position to a second stopping position in which the conduit completely deforms to interrupt the exit of pulverulent material; a device for actuating the first device for regulating the material to the second position of the latter when the bag has received most, but not all, of the amount of material it has to contain, and a device operated by the device of weighing, to drive the second output regulating device from the first to the second stopping position, when the sack has reached the total weight.
