Latest Patents

One of his latest inventions is the Dual Motor Aligner. This device is designed to feed sheets from a supply station while aligning them in X, Y, and θ coordinates. It features a pair of independently servo-controlled motors that are positioned on opposite sides of the sheet. Each motor drives a nip roller to transport the copy sheet, while sensors generate signals that represent the sheet's position. A controller utilizes these signals to adjust the motors' angular velocity, ensuring that the sheet is squared and properly gated into a work station.

Another significant patent is the Apparatus for Collating Sheets into Sets and Finishing Thereof. This improved offset collator includes a sheet gripper/injector transport station and an oscillating sheet receiving station. Copy sheets are transported to the transport station in a specified sequence, where they are gripped and then injected into a stack of sheets at the oscillating station. The system is synchronized to ensure that the sheets are inserted in the correct order and offset, culminating in an efficient offset stapling process.
