Summary

Multi Diameter High Speed Core Cutter

Appleton Multi-Diameter High Speed (MDHS) Core Cutter – The Perfect Solution to the challenge of profitable short run orders

The MDHS features chucked core positioning for cut length accuracy and two opposed knives – providing rapid cutting. Of course, the “classic” Appleton fixed blade cut provides a clean burnished cut. The MDHS core cutter provides quick internal diameter changeover utilizing low cost tooling.

  • Easy Operation – Operator interface is menu driven – providing simple, easy to learn operation. Operation is intuitive, reducing the operator learning curve and your staffing costs.
  • Quick Set-Up – The MDHS was designed for quick changeovers. Just change the chucking and cutting pads for the new core internal diameter. A single adjustment prepares the core cutter for a new core outside diameter.
  • Next Level Controls – The machine control network is PLC based using integrated motion control.
  • Built Touch and Smarter – The MDHS is designed and built in the Appleton tradition of machines that last and last. The welded frame provides a foundation for long service life while the control system monitors machine conditions and run time, prompting for service and preventative maintenance.

Upgrades

Automated Core Handling

Systems to load and unload your parent and cut cores. See our Appleton Automation™ web page for more details.

Printing System

Prints cut core length along core circumference.

Articulating Cut Core Accumulator Table

Trim and butt waste can be automatically separated from the cut cores. Cut cores can be discharged as they are cut, or accumulated for a single transfer to an accumulator table or conveyer. We can provide cut core handling systems with both side and end discharge to load bins and shafts.

Knife Lubrication System

Knife lubrication is available via a dual drip feed lubricator. The drip feed rate is individually adjustable for each knife.

The Appleton Cut

Appleton Manufacturing is the only core cutter manufacturer utilizing the specific combination of a fixed knife to slit the core and internally-driven core rotation while supporting the inner ply with a carbide pad, which is used to pinch the inner ply of the core between the cutting edge of the knife, allowing for a consistently accurate and clean cut all the way through the core. This technology allows for every core cut on an Appleton to have a crisp, clean and virtually dust-free polished cut. It’s what we at Appleton call “The Magic of the Appleton Cut”.


Appleton Manufacturing’s Core Cutters offer several benefits to slitting a core as opposed to saw or crush cutting them:

  1. Slitting minimizes or even eliminates hazardous core dust and related vacuums to mediate it
  2. Slitting produces repeatably accurate core lengths
  3. Slitting creates a high quality polished edge - The Appleton Cut
  4. Slitting dramatically reduces waste

Appleton’s cutting technology is available on all Appleton Core Cutters from our basic Semi-Automatic S210, through our Automatic A301 and A400s, as well as the Programmable P510 and P520 and up to our fully automated P610 and Multiple Diameter High Speed (MDHS) cutters.


Lower Quality Core Cutting Types

  • Saw Cutting: The saw cutting of cores is achieved via 1/8" thick blade that removes an 1/8" of core material. This results in the costly loss of core material (1” of material lost for every 8 cuts), and the material being removed is turned into airborne dust which is a breathing hazard, a local contaminant and can cause issues with downstream operations. This creates a situation that must be mediated by using noisy vacuum systems which must be cleaned and maintained at regular intervals. It is especially a problem in those industries where it is necessary to be clean and debris-free, such as the food packaging and healthcare-related industries. While accuracy tends not to be an issue for saw cut cores, the quality of the cut itself generally has inner ply tearing, outer ply tabbing and consistently rough core-edge scarring.

  • Crush Cutting: Crush-type cutters use a rotating blade when cutting cores. As the rotating blade makes its way through the core material the vibration and movement in the cutting system decreases accuracy in core lengths and creates a jagged edge on the core. At the end of the cut, the rotating blade comes to rest against a soft anvil. This quickly creates a ridge in the anvil and allows the inner ply of the core to be crushed inward, creating an imperfection that causes core problems in downstream operations. Another liability of the crush cut method, is that the rotating saw introduces a large amount of dust into the air and the surrounding environment This creates breathing hazards and maintenance problems that must be mediated by using noisy vacuum systems which must be cleaned and maintained at regular intervals.
