Ideal for narrow web applications, such as removing web wrinkles or controlling separation of slit webs, Perma-Bow bowed rolls from NimCor are as small as 1.5 inches in diameter. Perma-Bow rolls can operate at full line speed while the roll apex is rotated to aid in separating slit webs or eliminating soft spots and wrinkles. Precision-engineered bearing housings with pedestal or flange mounts simplify installation and servicing. Larger Perma-Bow bowed rolls are available in 3.5- to 7.5-inch diameters with fixed or adjustable bows and optional drive pulley. Roll coverings are available to meet any web or environmental challenge. NimCor engineers specify roll geometry and coverings to meet each customer’s application.
