Automated Corner Insertion and Seam Closing on One Machine
The Iowa Precision Cornermatic II Whisper-Loc Combo Automated Corner Insertion and Pittsburgh Seam Closing Machine is a unique, innovative machine that not only inserts and crimps corners into both ends of ductwork but also closes longitudinal Pittsburgh seams on the same ductwork when required. This design allows the operator to accomplish both corner insertion and seam closing on one machine without having to handle the ductwork between processes. The system will close the Pittsburgh seam on any ductwork that uses the duct flanges conforming to T25-a or T25-b under the SMACNA Duct Construction Standards. It will also close the Pittsburgh seam on ductwork that uses the raw edge or slip and drive method as well as slip-on flange type ductwork.
