Patent ID: 8186197

Claim:
A flange forming apparatus comprising: a support frame; a bed positioned atop the support frame, said bed having a width; a plurality of roll forming stations attached to the support frame along either or both longitudinal sides of said bed for forming a flange in a sheet of material, wherein each of the stations is adjustable in regards to a dimensional characteristic of the transverse flange to be produced or operated upon by the station; first inner and outer head rails disposed along a longitudinal side of said bed; second inner and outer head rails disposed along another longitudinal side of said bed, said first and said second inner and outer head rails supporting said plurality of roll forming stations; a flange height adjustment mechanism attached to the support frame, said adjustment mechanism being operably connected to the plurality of roll forming stations for adjusting the roll forming stations concurrently together in said regards to a dimensional characteristic of the transverse flange to be produced; and a bed-width adjustment mechanism including a first hand wheel positioned along one of said longitudinal side of said bed, first lead screws and a first chain mechanism for connecting the first lead screws to the first hand wheel for adjusting a position of said first inner head rail upon rotation of said first hand wheel to concurrently adjust a position of all of said plurality of roll forming stations supported by said first inner head rail in relation to said second inner head rail, and a second hand wheel positioned along the same longitudinal side of said bed as said first hand wheel, second lead screws and a second chain mechanism for connecting the second lead screws to the second hand wheel for adjusting a position of said second inner head rail upon rotation of said second hand wheel to concurrently adjust a position of all of said plurality of roll forming stations supported by said second inner head rail in relation to said first inner head rail, for adjusting said width of said bed for accommodating different sized sheets of material.
