Powered precise caliper adjustment, avoids board crush and guarantees board control. The VAC Stacker also features endless corded belts for board transport and targeted position to promote scrap elimination.

Overhead Vacuum Transport
A belt system carries the individual nicked sheets over the transfer deck to the incline conveyor.

Reject Collector Assembly
The VAC Stacker features a simple eject gate with collector chart for operator to get order sample or waste sheets out to operator side at any time while running. It can be combined with an optional vision control system.

Stacker Bay
Lead edge damage is prevented through servo deceleration in the stacking bay. Maintenance is simplified through an all-electric lift. Superior stack quality improves the bundle breaker process for higher productivity.
