Abstract:
In a roll forming machine of the type which forms an indeterminate length panel of a desired lateral profile from a uniform width supply strip of sheet metal having a pair of parallel straight edges, said roll forming machine defining a predetermined path of travel for said supply strip, an arrangement for selectively changing the profile along an edge of the panel comprising:a mounting plate member mounted to a side of the machine, wherein said mounting plate member is formed with a pair of spaced parallel slots elongated in the vertical direction; a module including first and second roll forming stations adapted for mounting to said mounting plate member with a selected one of said first and second roll forming stations along said predetermined path of travel, wherein said first and second roll forming stations are located on said module so that when said module is mounted to said mounting plate member with a selected one of said first and second roll forming stations along said predetermined path of travel the other of said first and second roll forming stations is vertically displaced from said predetermined path of travel, said module including a back plate formed with two parallel vertical rows of threaded mounting holes, said two rows being registrable with said pair of slots when said back plate abuts said mounting plate member; and a plurality of mounting bolts extendable through said slots into threaded engagement with selected ones of said mounting holes to secure said module to said mounting plate member at a selected one of two vertical positions so that a desired one of said roll forming stations is along said predetermined path of travel.
