Appleton A400 Automatic Core Cutter

Appleton's A400 Automatic Core Cutter is hydraulically powered to handle tougher materials. It features a powered core feed and an air-powered fixed knife for easy operation. The A400 can be equipped to handle the manual or automatic loading of cores. It can also be upgraded to operate with Appleton Automation™

  • 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, making productivity ever so easy to measure. It also prompts operators when the hydraulic filter needs service
  • 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 hydraulically fixed knife cuts to within +/-0.010 inch of the targeted length. Special hydraulic valving provides cut-rate control to match cutting speed to the material properties
  • Clean, Polished Cuts – Special cutting hardware produces smooth cuts without melting edges on plastic tubing or overheating adhesives on tapes. The fixed knife of the A400 makes clean, burnished cuts while generating virtually no dust
  • 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
