Patent number: 10480814Abstract: An apparatus and a process for forming an oval shaped duct, as well as a round duct for all required sizes and thicknesses for an AC system, in one continuous operation where two driving rolls advance a flat metal sheet to a multi-positioning bending roll, where the bending roll is moveable to a bending position for different curvatures and a non-bending position. The driving rolls advance the sheet through while the bending roll bends the sheet to form the curved sides, and the bending roll in the non-bending position form the flat sides of the oval shaped duct. A position sensor detects the position of the flat metal sheet in the rolls to control the location along the sheet where the bending roll is moved to either of the bending or non-bending positions while the driving rolls are stopped.Type: GrantFiled: December 15, 2017Date of Patent: November 19, 2019Inventor: Jose E Rossi
