Abstract: A vertical Pittsburgh Seam closing apparatus having a base supporting surface, a track mechanism for moving a carriage assembly which holds seam forming members used to close a Pittsburgh Seam, a pair of upper and lower guide members for guiding the duct section into a proper vertical position, and upper and lower clamping members positioned inside the duct section and adjacent the inside portion of the Pittsburgh Seam to be closed, the upper guide members and clamping member being selectively movable and adjustable for accommodating different duct section lengths. In one embodiment, the seam forming assembly includes three roller members mounted in vertical arrangement to each other, one roller member being V-shaped in configuration and the other two roller members being substantially cylindrical in shape. The V-shaped roller member may also include one or more projecting members for forming dimples in the closing process to prevent shifting and/or slipping of the closed seam.

Abstract: An insulation cutter for a liner application machine in an assembly line and method of operation that cuts an insulative thermal blanket by stopping the liner application machine momentarily to allow for a rotary cutter to traverse the width of the belt (and the width of the thermal insulation blanket) and potentially return back to its original position. The machine is then restarted and allowed to continue to feed.

Abstract: The present insulation spool apparatus is adapted for lining ductwork with insulation material and includes a pair of spaced apart first and second spool plates for holding and mounting a plurality of rolls of insulation material at one time, each individual roll of insulation material being rotatable into operative position for use. Each spool plate includes a plurality of receptacles for engaging and holding one end portion of an insulation roll support shaft. The spool apparatus may further include a plurality of hook plates for guiding the support shafts into locking engagement with the spool plates, locking mechanisms for holding the support shafts in a locked position with the spool plates, one or more paddle assemblies for providing sufficient tension force to each respective roll of insulation material for preventing premature unwinding during use, and a feeder mechanism for feeding and loading such rolled material onto the spool apparatus.
