Parent Core Length Range

  • 5' to 14' (available in 1 foot increments).
  • Note that core diameters under 3" limit machine length.

Core Diameter Range

  • 3" I.D. to 13" O.D.
  • With options, range can be expanded down to 1" I.D. or up to 26" O.D.

Wall Thickness

  • 1/4" to 5/8" (includes .660" cores).
  • With options, range can be expanded down to 1/8" and up to 3/4". For heavier walls, contact Appleton Mfg. Division.

Cut Length Range

  • Minimum cut determined by core integrity (typically equal to wall thickness).

Maximum Length

  • Reference standard cut length in chart under Layout tab.
  • Note optional extended target for longer cut lengths.

Cut Length Tolerance

  • +/-0.010" (3 Sigma).

Utilities

  • 3 phase electrical power. 15-25 amp circuit required depending on options.
  • 80 psi plant air. 1 scfm @ 50 cuts/minute, (cut rate, operator and core dependent).

The Appleton Cut (Slit Cutting)

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
2.) Slitting creates a high quality polished edge - The Appleton Cut
3.) 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

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.

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.

Stroke Limit

  • For core wall thickness below 1/4" (prevents expansion of thin wall core I.D.).

Extended Target

  • Permits cut core lengths up to extended cut length column in chart (see Layout tab).

Large Core Diameter

  • Extends diameter capacity up to 26" O.D.

Additional Support Rollers

  • Permits core diameters down to 1" I.D.

Knives

  • A variety of options that match the cut to your materials.

Electrical System Controls

  • Motor starters, control voltage transformers and power disconnects are included. Customer specified components or locations optional.

Digital Readout

LCD read-out of target position (cut length) for consistent settings between operators

Auto Indexing Knife

Rotates the knife 3/16" automatically at operator preset number of cuts. Provides 40 knife positions for uniform cut quality and extended blade life.

Patented IDC (Instant Diameter Change) Mandrel System

Appleton's patented IDC mandrel system provides a multiple core diameter capability with a single mandrel and interchangeable cartridges. See the Core Cutter Upgradespage for more details.

Automated Core Handling

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

  • Simply Automated – Cores are automatically advanced, automatically cut. Operator needs only set the target length.
  • Intelligent Control – The PLC control panel features push-button simplicity with an LCD screen that displays prompts and operator input. The PLC captures and displays run data and system status.
  • Simplified Adjustment – Different core diameters require a simple change of the core mandrel. When core diameters change more frequently, Appleton's IDC (Instant Diameter Change) option will speed changeovers and improve productivity.
  • Precise Cuts – The air-assisted fixed knife cuts to within +/-0.010 inch of the targeted length.
  • Clean Cuts – The fixed knife of the A301 makes clean, burnished cuts while generating virtually no dust or noise – making for a superior cut, a quiet machine and a better work environment.
  • Expandable – With its PLC intelligence, the A301 can be easily expanded with Automated Parent and Cut Core Handling, Auto-Indexing Knife and other options that free your operators for other tasks.
  • Energy Saving – Every Appleton core cutter features an auto-shutoff that turns off the cutter when left unattended, eliminating unnecessary energy costs while minimizing wear on moving cutter parts. As always, workers are safer when unattended machinery is not running.
  • Installation and Training – Professional installation and training services are readily available from skilled technicians with years of core cutter experience.
