Latest Patents
Gehrke's latest patents include a "Non-recirculating, die supplied doctored roll coater with solvent." This innovative coater incorporates a die, a reservoir, a gravure cylinder, and a doctor blade for applying coating fluid to a moving surface. The design allows for the flow rate of coating fluid to be controlled, eliminating the need to recycle surplus coating fluid. Additionally, the coating fluid can be quickly replaced with a solvent in the reservoir when not in use, reducing the occurrence of defects due to excessive evaporation and premature solidification.
Another significant patent is for "Differential-speed gravure coating of magnetizable layers." This invention allows for the application of a magnetizable layer to a flexible backing web at high speeds. The gravure coating process is enhanced by independently driving the backing web at a speed that differs from the surface speed of the gravure roll. This method has achieved especially high coating speeds, improving the overall efficiency of the process.
