Latest Patents

One of Dennis's notable inventions is the "Vacuum Die Mount." This patent describes a method and apparatus for securely mounting a rigid cutting die onto a die cylinder. The technology features a bubble seal that bridges gaps between the die and the cylinder, allowing a vacuum to be applied to pull the die into conformity with the cylinder's surface. Additionally, it includes an axial keyway for precise circumferential positioning and a bolt for axial location. To ensure operational integrity, beam sensors and light reflectors are integrated to detect incorrect die placements, thus safeguarding the apparatus by shutting it down if an error is present.

Another innovative patent from Dennis is for "Mounting Printing Plates." This apparatus streamlines the process of attaching flexible printing plates to a printing cylinder. By utilizing subatmospheric pressure and selectively applied valves, the printing plate is efficiently drawn against the cylinder. A notable feature includes grooves in the cylinder surface that distribute pressure evenly. This setup not only facilitates quick changes of printing plates but also ensures that the printing process maintains high fidelity.
