Title: John F Trogan: Innovator in Paper Folding Technology
Introduction
John F Trogan is a notable inventor based in Ashland, WI (US), recognized for his contributions to the field of paper folding technology. With a total of 4 patents to his name, Trogan has developed innovative solutions that enhance the efficiency and effectiveness of paper interfolding machines.
Latest Patents
One of Trogan's latest inventions is the "Resilient Creaser." This invention relates to a paper interfolding machine that features first and second folding rolls mounted adjacent to each other for rotation about parallel axes. The machine utilizes porous tissue paper carried by each roll, incorporating a wedge-shaped protrusion on the first folding roll and a mating recess on the second folding roll. A resilient member fills a portion of the mating recess, forming an elastic anvil that is deformed by the protrusion to crease a sheet of paper received in the nip between the rolls. Additionally, vacuum ports on the second folding roll are employed to selectively adhere the sheet during the creasing process.
Another significant patent is the "Apparatus for Folding and Stacking Paper Products." This invention outlines a method and apparatus for continuously folding multiple webs of material, such as paper, cutting them into segments of predetermined length, and stacking the segments together until a desired number is reached. The stack is then discharged while a new stack is initiated, showcasing Trogan's innovative approach to paper handling.
