Working Method and Machine Equipment

Working Method

  • The tubes are fed fully automatical out from the magazin into the Index Cutter. Alternatively the TWIN 4 -series could be ordered in semi-automatic version with manual parent core loading.
  • Cutting length(s) and quantity are to be programmed by the operator. The graphic HMI-TouchPanel supports look-and-feel navigation. Cutting data could be transfered to the TWIN 4 by internet communication as well.
  • The belt driven servo unit pulls in the parent core completely when starting the cutting cycle. The parent core length is scanned in the machine, programming is not needed.
  • According the programmed length(s) the tube is positioned and cut off using the TWIN-knives (circular knife). First and last trim cut is seperated to the back of the machine.
  • Cuts pieces are dropped directly into a box or they are ejected as complete charge onto the optional available storage table.

The machine is equipped with

  • Siemens Touch Panel with graphical user interface, incl. Self-Diagnostic - System
  • Progammable Logic Controller Siemens PLC-Control
  • Positionable Servoaxis with maintenance-free Belt Drive
  • 2-Knives-Cutting System with pneumomechanical controlled Bell-Crank-Lever-Unit or optional servoprogrammable Kniveaction
  • Top and lower CoreCutting. Support with automatic Adaption to core OD. No setup required.
  • Pneumatical activated. Waste Scraper with automatic Adaption to core OD. No setup required.
  • Waste Sorting for first and last trim cut
  • Adaptive Speed of Rotation. The speed of rotation is increased automatically the shorter the core gets.
