Latest Patents

One of Ronald Callan's latest patents is an "Anti-wrap device for a web press." This innovative system and method are designed to prevent a broken printing web from wrapping around or fouling the blanket cylinders of printing press units. The system includes a web tensioning device located downstream of the printing press units, which maintains tension on a broken web and pulls it away from the printing units. It features a series of web disturbance detectors that identify disturbances indicative of a web break. Upon detection, a pair of anti-wrap rollers engage the web to exert tension and pull it from the printing units. These rollers rotate at a surface speed greater than that of the printing rolls and include interlocking peak and valley portions for better grip. Additionally, the system incorporates a flow bar to reduce false detections and a blow-down bar to safely direct the broken web to the ground.

Another notable patent is the "Apparatus and method for detecting printing press web breakage." This apparatus is designed to detect breakage in a web of material traversing a machine. It consists of a housing that mounts three transducers. The first transducer emits a burst of energy, which is reflected off an object, producing an echo signal. The second and third transducers receive portions of this echo signal, with the strongest portion being used to determine if the web is broken.
