Abstract
A quick change cassette system for a multi-roll leveler, such as may be used to flatten strips of material. The quick change system is designed for use with a leveler having an upper and lower cassette assembly containing upper and lower work rolls, respectively. The quick change system is also particularly suited for use with a lower work roll cassette that is mounted to the leveler in a hanging arrangement. A cart is mounted to the bottom side of the lower work roll cassette. Wheels are attached to a bottom portion of the cart to guide the cart into and out of the work envelope of the leveler along a set of guide rails. The cart can be moved manually or by means of a motor, cylinder, or other actuator. The cart remains attached to the lower work roll cassette during operation of the leveler. An upper work roll cassette may also be removed or installed to the leveler along with the lower work roll cassette.
