Title: The Innovative Contributions of Karl J Warren
Introduction
Karl J Warren is a notable inventor based in Hudson, WI (US), recognized for his significant contributions to coating technology. With a total of 5 patents to his name, Warren has developed innovative solutions that enhance the efficiency and effectiveness of coating processes.
Latest Patents
Warren's latest patents include a Non-recirculating, die supplied doctored roll coater with solvent. This invention incorporates a die, a reservoir, a gravure cylinder, and a doctor blade for applying coating fluid to a moving surface. The flow rate of coating fluid to the gravure cylinder is controlled to equal the rate at which coating fluid is consumed by the coating process. This eliminates the need to recycle surplus coating fluid. Additionally, the coating fluid can be quickly and conveniently replaced with a solvent in the reservoir when coating is not being performed, reducing the occurrence of coating defects arising from excessive evaporation of solvent and premature solidification of coating fluid. Another significant patent is the Ultrasonically assisted coating method. This method applies a smooth layer of coating material on a surface of a moving web. An ultrasonic energy generator excites the line of initial contact between the coating material and the web at a uniform ultrasonic intensity, selected in combination with the properties of the coating material. The coated web achieves a thin, uniform crossweb thickness with low thickness variations.
