Latest Patents
One of Mulry's latest patents is the "Winder Roll Starting Apparatus for Thick Webs." This invention features a scraper mounted around the axis of a winder drum, designed for circumferential movement. The scraper has a semi-cylindrical concave surface that extends in the cross machine direction, meeting a second surface to form a scraping edge. This scraping edge engages the winder drum, effectively scraping a web from its surface and pressing it into contact with double-sided sticky tape on a winder core. An alternative embodiment includes a flexible blade that functions similarly to a spatula, ensuring efficient web transfer.
Another notable patent is the "Winder Splicing Nip Guard." This guard is mounted for rotation about the downstream drum of a winder that supports a paper roll. It features a D-shaped leading edge that approaches the paper roll. The leading edge is articulated, allowing it to close a switch that stops the winder if an operator's hand becomes wedged between the leading edge and the paper roll. A hydraulic actuator facilitates the guard's rotation, enhancing safety by limiting operator access to the nip formed between the paper roll and the downstream winder drum.
