Latest Patents

One of McCarville's latest inventions is the "Extended nip press apparatus." This apparatus is designed for pressing a web of paper as it passes through. It features a rotatable backing roll and a press shoe with a concave surface that works in conjunction with the backing roll. The design allows for an elongated pressing section, which is crucial for maintaining the integrity of the web during processing. The shoe includes an upstream portion that is urged toward the backing roll, while a downstream portion is resiliently positioned to control the pressure profile applied to the web, preventing delamination.

Another significant patent is the "Extended nip press with oscillating blanket for extended wear." This invention incorporates a blanket that moves over a shoe pressed against a backing roll to create a press nip. A hydraulic system enables automatic continuous oscillation of the blanket, which minimizes wear by ensuring that no single area experiences prolonged fatigue. The positioning of the blanket ends is managed by hydraulic pistons, and a controller reverses the blanket's motion when sensors detect that one end has reached a stop.
