Patent ID: 11472148

Abstract:
An apparatus for making a self-opening wide mouth bag pack includes a supply of flexible film material. An extruder forms a continuous tube. A flattener flattens the tube. A first sealer forms a bottom seal across a width of the flattened tube. A cutter cuts the flattened tube into bag blanks has a bag mouth at a predetermined distance from the bottom seal. Second and third sealers form angled seals at lower corners of the bag blank forming a flat bottomed bag. An adhesion knife penetrates the bag pack adhering adjacent bag blanks together in the bag pack. An aperture maker forms apertures for suspending the bag pack from a dispensing rack. The pack is attached to the dispensing rack and the front wall of the subsequent bag is adhered to the rear wall of a first bag, thereby causing the first bag to open when pulled from the rack.
