Patent number: 8910548Abstract: A finishing apparatus for ductwork having a duct body with at least one open end. The finishing apparatus includes an operation platform for selectively supporting the ductwork and a first wrapping mechanism integrated with the operation platform, the first wrapping mechanism including a first dispenser for dispensing a first film. The finishing apparatus further includes a first cutting mechanism integrated with the first wrapping mechanism. In operation, the first wrapping mechanism selectively dispenses the first film adjacent to and against the open end of the ductwork as the ductwork is moved a predetermined distance down the operation platform. The first cutting mechanism selectively cutting the first film after the ductwork has moved the predetermined distance down the operation platform.Type: GrantFiled: August 29, 2012Date of Patent: December 16, 2014Assignee: Mestek Machinery, Inc.Inventor: Michael C.

Patent number: 8458884Abstract: An apparatus for forming a duct includes a bending apparatus and a support apparatus. The bending apparatus includes a table, a cut off beam, and a leaf hinged to a forward edge of the table. The cut off beam is movable toward and away from the table to clamp or release a metal web being fed forward across the table and the leaf. The cut off beam repeatedly clamps the metal web to the table while the leaf pivots toward the cut off beam to form a duct section. The support apparatus includes a cross rod movable along pivoting support arms. As the metal web is bent to form the duct section, the support arms and the cross rod are moved to internally support the duct section.Type: GrantFiled: June 22, 2012Date of Patent: June 11, 2013Assignee: Mestek Machinery, Inc.Inventors: Michael C. Borwig, Scott Sloan, Richard Burkart, Steven Kerska, John Welty
