Abstract
A roll forming machine includes side roll stands which are changed by use of a cart and set up fixture which are movable parallel to the pass line through the stands. When a side roll stand is to be changed, a changing cart is moved into position such that rails on the cart are aligned with rails on the fixed support supporting the side roll stand. The side roll stand is moved off of the fixed support and onto the cart, and then moved from the cart into an empty station on a set up fixture. A retooled stand is moved from another station on the set up fixture onto the cart and then from the cart back onto the fixed support. Accordingly, time to effect changeover of a stand is reduced substantially from prior art methods, and no heavy equipment, such as a crane, is required.
