gamma 502 stacker/bander

With the gamma automatic delivery, you can rely on higher productivity at lower personnel costs. Sturdy, easy-to-handle stacks ensure easy handling and low labor requirements. The gamma is mobile with a small footprint that can be easily used with folding machines, saddle stitchers, gathering machines, and digital finishing lines.

The flexible design allows for the optional use of a paper band to secure loose bundles to keep them from falling over.  The stacker presses, counts, measures, stacks, bands (if needed), and pushes to a buffer table in running direction. With speeds out up to 600 bundles/h per stream, the gamma creates a very effective, low labor requirement process.
