Title: Innovations of Robert Stuart McCallum
Introduction
Robert Stuart McCallum is a notable inventor based in Caledon, Canada. He has made significant contributions to the field of electrostatic charging apparatus and media sheet transport systems. With a total of six patents to his name, McCallum's work has advanced the technology used in various printing and media handling applications.
Latest Patents
Among his latest patents is the "Electrostatic charging apparatus and method for sheet transport." This invention features a media sheet drive that utilizes a continuous belt made of dielectric material to transport sheet media. The design includes a launch mechanism that effectively launches a sheet medium onto the belt's surface. A charging circuit, which incorporates a charging roller, is employed to charge both the sheet medium and the belt as the medium is launched. This charging process generates an electrostatic tacking force that secures the sheet medium to the belt. Additionally, the charging roller serves to smooth out any curled edges of the paper, ensuring that the entire sheet is subject to the electrostatic tacking force.
Another significant patent is the "Media sheet transport apparatus and method." Similar to his previous invention, this media sheet drive also features a continuous belt of dielectric material. It includes a launch mechanism for sheet media and a charging circuit with a charging head. This design generates an electrostatic tacking force while incorporating a neutralizing circuit positioned downstream to balance the charge and reduce the electric field near the belt's surface, thus preventing any adverse effects on the printing process.
