Title:
AUTOMATED PROFILE CONTROL-ROLL FORMING
Document Type and Number:
WIPO Patent Application WO2001032328
Kind Code:
A3
Abstract:
A roll forming machine comprises a plurality of stations for progressively bending a flat strip of material such as metal into a formed product such as a building stud. The machine includes adjusting means for adjusting the spacing between the roll forming dies to accommodate differing thicknesses of metallic strip. Each station may be adjusted along an angle of adjustment which is related to the bend angle at that station. A single adjustment actuator adjusts all of the stations even though each station may be adjusted a different amount and at a different angle. In a preferred embodiment, the amount of adjustment at each station may be different from other stations being adjusted to provide adjustment not only in the correct direction but also in the correct amount.
