ABSTRACT:
An improved roll forming machine has a machine base, a mounting plate affixed to said machine base, a fixed base plate mounted to said mounting plate, and a movable base plate laterally movable with respect to said fixed base plate. A main block is mounted to said fixed base plate in which are journalled a first plurality of pairs of roller receiving shafts. Journalled to upright stands affixed to the movable base plate are a second or equal plurality of axially aligned roller receiving sleeves which fit over reduced diameter portions of the shafts and are rotated thereby. Movement of the movable base plate causes the sleeves to slide laterally on the shafts and change the width of the workpiece produced by the roll forming machine.
