Metering and Accumulation

An Infeed Metering Conveyor spreads product evenly across the full width of the integrated Pillo-Pak™ conveyor. This lets the rest of the machine process the maximum amount of product possible.

A Sloped Chute is the next stage, it is here that product is received, oriented, sorted, and collated, so it is lined up and ready for the rest of the process.


The Infeed Accumulator portion of the machine transports the arranged product, while providing the accumulation necessary to be sure that the downstream parts of the machine are never "starved" for product, it also creates a "slow spot" with high visibility, this area allows for visual product inspection.



• Adjustable metering and accumulating speeds, for smooth product flow

• Flexible plastic belting over nose bars for smooth product transfer without rollers

• Plastic mat top infeed accumulation with adjustable product guides



It is the Grouper that places the product into the desired arrangement for packaging, both configuration and size. Then it releases the entire group for slicing.



• Individually positioned lane guides for products from 2" to 5" wide

• Variable belt speed for improved product handling

• Individually adjustable lane sensors verify a full group for release. Each sensor can be electronically blocked when required

• Gentle hold back of incoming product by vertically acting pressure board



Our Dual Band Slicer then cuts the product. The slicer is capable of numerous cut types, and is fully configurable to cut differently for different product runs.



• Dual band slicer for either single or double slicing of roll products

• Blade guard on infeed end of slicing head to quickly stop blades and conveyor when activated

• Sensor to detect broken blades

• Double to single slice without blade removal

• Separate drive for top conveyor


Final Packaging

The Sealer is the final step; product is packaged into a custom produced plastic film, evacuated of excess air, and tightly sealed on all sides. If you desire, you can also split the package into sections with optional single or multiple center seals and skip seals.



• Independent heat controllers for cross seal, side seals and cut-off ribbon

• Controlled separate film feed

• Efficient package air removal

• Reduced cross sealing time

• Self contained PID controller for accurate cross seal temperatures

• Separator and perforator options

TriPak option for multiple adjustable centerseals
