New Product

Cornermactic 11 Whisperloc Combo

The CORNERMATIC II® ~ WHISPER-LOC® 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 TDC® or 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 only on ductwork that uses the raw edge or slip and drive method.

Corners for this automation are quickly loaded into the magazines from the shipping cartons.  The corners come oriented and stacked in the carton for quick and easy loading. The CORNERMATIC II® ~ WHISPER-LOC® COMBO is capable of utilizing either standard boxed corners or pre-packaged disposable cardboard sleeves with a simple quick magazine changeover. The standard boxed corner magazines hold 90 corners and the “new cardboard sleeved corners” come loaded with 80 corners per sleeve.  The process is virtually noiseless.
