The Cornermatic II Whisper-Lock Combo is a unique, innovative machine that not only inserts and crimps corners into both ends of ductwork but 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 corner insertion is a pneumatically operated process that rapidly and automatically inserts and crimps corners into both ends of ductwork that uses the transverse duct connector (TDC) or transverse duct flange (TDF) method of joining. This unit automatically places a corner piece into a corner on each end of the duct and crimps them securely and permanently into place.
The seam closing is powered by an electric motor and gearbox using a Variable Frequency Drive. It will accommodate duct with various end joining methods. It will close the Pittsburgh seam as well as insert corners on any ductwork that uses the duct flanges conforming to T25-a or T25-b under the Duct Construction Standards. It will also close the Pittsburgh seam on ductwork that uses the raw edge or slip and drive method.
The Cornermatic II Whisper-Lock Combo requires only compressed air and 460/3/60 current to operate but other voltage and electrical requirements available.
The Cornermatic II® Whisper-Loc® Combo is capable of utilizing either standard boxed corners or the StrapPak™ – 80 corners in a double-strapped package – to be quickly loaded into the magazine directly from the shipping carton or traditional Cornermatic type and EZ Connector® type corners.
