Paper Straw Making Machine

Manufacturing paper straws is a completely different process to producing plastic straws. Typically constructed of 3 plies of paper, the plies are bonded together with a small amount of water-based adhesive using a core-winding machine, or hot melt adhesives using a slot nozzle machine for very fast production lines. Straw manufacturing requires several steps. First, the plastic resin and other components are mixed together; the mixture is then extruded in a tube shape; the straw may under go subsequent specialized operations; and finally the straws are packaged for shipment. Paper straws allowed them to avoid making direct contact with the glass while drinking. At one point, Stone was producing two million paper straws a day in his factory. He even took it one step further with the genius “double straw.” The original patent document features diagrams and a full explanation of the process
