Equipment / Stackers GSS and GSSB Servo Stackers

All Forpak stackers are unique graphic touch screen-selectable servo stacking units that count and create vertical stacks of product.  The stacks, which are created and discharged from the Stacker onto a continuous-running Take Away Conveyor, can then be manually packed into boxes or trays, or fed downstream to automated packing equipment.

Stacker Model GSS, which stacks at a rate of 100 pieces per minute per lane, is ideal for stacking frozen meat patties and bakery products.

Stacker Model GSSB (Bypass Conveyor) offers the same functionality as Model GSS, but also features a Bypass Conveyor within the stacker. The bypass allows products that do not require stacking to pass through the stacker untouched. This model can easily convert between stacking and bypass conveying.


Flexibility by Design

Forpak Stackers are the industry’s only stackers with built-in flexibility to handle products of most sizes and shapes with minimal design changes.

A key component of Forpak’s Flexibility by Design is the Automated Interleaving (paper feed) option.  With this option – available on Models GSS and GSSB – paper is interleaved between individual product pieces, thereby eliminating the need for manual intervention at this stage of the process.Maximum rate is 80 pieces per minute per lane.
