Latest Patents

Among Fitzpatrick's latest innovations are two noteworthy patents:

1. **Articulated Rider Roll System and Method**

This invention encompasses a rider roll system designed to exert an even nip load force along the surface of a roll of paper being wound from a continuous web in a winder. It includes a plurality of rider roll wheel elements connected to a common source of hydraulic pressure, ensuring consistent rolling nip force against the wound paper roll. The system employs a beam that is translationally movable above the roll and adjusts based on the roll's diameter, controlled by a programmable logic controller. This design allows individual wheel elements to apply a cushioned nip force, ensuring the integrity of the paper during the winding process.

2. **Tail Stopping and Knockdown Device**

This device slows cut sheets in sequential flow by nipping the trailing edge as they leave a high-speed conveyor system. This technology facilitates smooth transitions to a stacking pile while maintaining operational efficiency. It features various embodiments, including a brush carrying roll, an oscillating roll on a lever arm, and an air jet. Additionally, the invention includes ream removal apparatus to assist in removing paper reams from the stacking pile seamlessly.
