  • Patent number: 5899563
    Abstract: A corrugating adhesive is produced on an as needed continuous basis using a mixing chamber containing an agitator and a testing chamber including a viscosity sensor. Each adhesive ingredient is proportionally added to the mixing chamber in a total volumetric rate corresponding substantially to the rate of use in a corrugating machine. A portion of a raw starch slurry is adjustably diverted to mix with a basic agent to control adhesive viscosity, with the amount not admixed added to the mixing chamber. Thus, the amount of adhesive made is in balance with the amount used, allowing fresh adhesive to be provided throughout a corrugating run, without a large hold up of adhesive, thus reducing capital costs and adhesive waste.
    Type: Grant
