ABSTRACT:
Roll winding device and process for use, e.g., in a reel slitting device. The roll winding device includes a roll carrier device, a pneumatic pressure release device including a plurality of blow boxes having top sides with escape nozzles, and a rocker arm on which the blow boxes are mounted in articulated pairs. The blow boxes are swivelably adjustable on tilting axes that run parallel to a roll axis. The process includes positioning the blow boxes beneath a peripheral surface of a roll being wound on the winding machine and ejecting air through the escape nozzles in the blow boxes directed toward the peripheral surface to orient the top surface of the blow box substantially parallel to a tangent of the peripheral surface and to position the top surfaces of the blow boxes a substantially same distance from the peripheral surface. In this manner, the ejected air forms an air cushion under the roll.
