A method and apparatus for the automatic filling of plastic bags with, for example, elastic, soft and deformable contents. In order to provide for the automatic handling of empty bags without intermediate, especially manual, steps, the invention provides that the empty bags are attached by extending flaps to a plastic carrier web across a tear line. The apparatus of the invention places a quantity of goods into the bag by means of an axially moving filling piston which passes between spreadable jaws that hold the bag open. The continued motion of the filling piston eventually exerts a force sufficient to cause fracture along the tear line and separation of the filled bag from the flap which stays attached to the carrier web. The piston then moves the filled bag into position for sealing. A number of embodiments is presented.
A method for automatic filling of container bags, said method including supplying empty bags on a carrier web at a scheduled cyclic rate, opening the first bag by means of an opening funnel, placing the goods in the bag and removing the bag from the carrier web and wherein, according to the invention, the method comprises the steps of:
An apparatus for automatic filling of container bags, said apparatus including a cyclically actuated conveyor mechanism for imparting step-wise motion to a carrier web, on which empty bags are seriatim permanently attached by a portion thereof;
