A sealant system for operation with a metal workpiece comprises a frame, a cam assembly mounted to said frame, a sealant reservoir, a sealant application unit connected to said sealant reservoir, and a control module for coordinating operation of said cam assembly and said sealant reservoir, wherein said control module comprises a temperature sensor for monitoring the temperature of said sealant, an integrated heating system for heating said sealant and a controller in communication with said temperature sensor and said integrated heating system.

Sealant system for metal seams

A method of forming a duct section from a web of material includes the steps of forming a series of perforations in a web of material, the series of perforations defining an outline of one of a hole or notch in a finished duct section, forming a male lock bend and a female lock seam in first opposed edges of the web of material, forming flanges in second opposed edges of the web of material, removing the portion of material interior to the series of perforations to form the hole or notch, and bending the web of material to form the finished duct section.

Method and apparatus for manipulating metal workpieces

A sealant system for operation with a metal workpiece comprises a frame, a cam assembly mounted to the frame, a sealant reservoir, a sealant application unit connected to the sealant reservoir, and a control module for coordinating operation of the cam assembly and the sealant reservoir, wherein the control module comprises a temperature sensor for monitoring the temperature of the sealant, an integrated heating system for heating the sealant and a controller in communication with the temperature sensor and the integrated heating system.

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.
