Patent number: 8459081Abstract: A roll former has a plurality of paired die assemblies spaced apart across a midline of the roll former, and a web of material is fed through the roll former along the midline for operations by the die assemblies. The spacing between each pair of die assemblies is uniformly adjustable by way of mounting the die assemblies on collector plates movable toward and away from each other by linear actuators such as jack screws. Smoothness of movement is enhanced by supporting the collector plates only on the linear actuators. Precision of positioning is enhanced by using jack screws as the linear actuators.Type: GrantFiled: June 29, 2010Date of Patent: June 11, 2013Assignee: Mestek Machinery, Inc.Inventor: Randy Runyan

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.
