Abstract
An apparatus for filling bags with bulk material includes a filling device for consecutively charging bags with the bulk material; a traction device leading into and out of a region of the filling device; and a plurality of spaced spreading devices, carried by the traction device, for expanding each bag to facilitate charging thereof by the filling device. Each spreading device has first and second mutually cooperating pivotal spreading fingers having a retracted state and an expanded state. The apparatus further has a first cam track extending generally along the traction device; a second cam track extending generally along the first cam track and being spaced therefrom; a device connected to the first cam track for lowering each spreading device relative to the traction device to introduce the spreading fingers into a bag located below the spreading device; and a device connected to the second cam track for placing the spreading fingers of each spreading device from the retracted state into the expanded state after introduction of the spreading fingers into the bag.
