1. 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 driving said supply
strip along a predetermined path of travel through a plurality of roll forming stations and comprising:
a rigid framework including a pair of rigid parallel side frames interconnected one to the other by a plurality of rigid parallel
upper and lower transverse members to form a rigid cage having an interior and a width between said side frames;
a plurality of mounting blocks each supported on a respective one of said lower transverse members adjacent a first one of
said pair of side frames, each of said mounting blocks having an upper horizontal surface and a plurality of spaced mounting
holes extending into said each mounting block from said upper surface, said plurality of mounting holes for each of said mounting
blocks extending along a respective line orthogonal to said pair of side frames and having identical spacing on all of said
plurality of mounting blocks, and wherein the upper horizontal surfaces of all of said plurality of mounting blocks lie along
a single horizontal plane;
a first mounting rail secured to at least two of said plurality of mounting blocks by at least two mounting threaded members
each extending through a respective opening in said first mounting rail and into a respective mounting hole in a respective
one of said at least two mounting blocks, wherein each of said respective mounting holes occupies the same relative position
in its respective mounting block;
a first tooling rail;
at least one fastener detachably securing said first tooling rail to said first mounting rail; and
at least one set of roll forming elements each defining a roll forming station secured to said first tooling rail;
wherein said first tooling rail with said at least one set of roll forming elements secured thereto is dimensioned so that
it can be manipulated into and out of said cage vertically between an adjacent pair of upper transverse members without removing
said first mounting rail from said cage.
