Abstract
A deckle-edge-simulating apparatus generally comprising a conveyor system for transporting a web of paper through the apparatus, and a novel deckle-edge-simulating assembly operatively associated with the conveyor system. The deckle-edge-simulating assembly generally includes a configured transport roller or anvil in association with a deckling fixture. The anvil is disposed beneath the web of paper, and includes one or more circumferential grooves in its surface. The deckling fixture includes a blunt-edged blade extending from and between a pair of nip forming rollers disposed on either side of the blade, and into one of the grooves of an anvil. As the web of paper passes across the anvil, the blunt-edged blade operates to burst the fibers of the paper to create a simulated deckled edge. The nip forming rollers serve to firmly hold the web of paper in position during this deckling procedure.
