发明名称 Quick change metal stud to hemmed track roll forming system
摘要 An apparatus and method for selectively forming metal stud and track members from sheet material, the apparatus including a stud forming assembly capable of transforming the sheet material into a stud member as the material exits the stud forming assembly, and a track forming assembly capable of receiving the stud member as it exists the stud forming assembly and thereafter transforming the stud member into a track member. The track forming assembly is selectively moveable between an operative position wherein the track forming assembly is coupled to the stud forming assembly to receive the stud member as it exits the stud forming assembly, and an inoperative position wherein the track forming assembly is positioned such that it cannot receive the stud member as it exits the stud forming assembly. The apparatus may also include punch and shear mechanisms for performing various operations on the sheet material.
