Tray & Carton Formers

Switchback Group offers its Trayforming and Closing equipment, with over 35 years in the packaging industry. We specialize in the conceptual development, design, and manufacture of high quality equipment including trayformers, tray closers, flap closers, and rotary carton openers.

GF42S-3 Trayformer

The GF42S-3 is a rugged, high speed, servo controlled shuttle style tray and carton former.  With cycle rates up to 45 cartons/minute, the GF42S-3 can handle most challenging applications.  Dual heads are available, and quick-change tooling sets allows for multiple tray sizes to be run on the same machine.

The GF42S-3 features controlled, auto-advance carton magazines, servo tray shuttle axis for high speed, precise glue dispensing.  OEM glue system (Nordson, ITW, etc.), and servo forming axis are standard to allow rapid, but gentle plunge-forming of carton blanks.  With the ability to vary the cycle of the servo forming head, we can customize the forming of each carton style to meet the unique forming aspects of any application.
