  • Touch-control-panel P1 with integrated SD card reader and USB slot. The P1 guarantees an intuitive operation


  • Interchangeable swivel unit - easy exchange from hot air to hot wedge or vice versa
  • Differential transport possible during sealing
  • No buttons, no pressure gauges: One touch screen and 100% parameter control
  • All parameters are controlled electronically:
    One integrated control board monitors the heat-sealing temperature, the air flow, the roller pressure and the two motors for the top and bottom roller
  • Proportional valves enable the dynamic adjustment of the air flow and roller pressure
  • Two precision-controlled motors permit an extremely accurate differential transport
  • 2-axis swing in mechanism:
    The nozzle or wedge can be very accurately adjusted without tools by using a compound slide rest
  • Hinged post: The bottom post holder can be turned over 180° as desired
    Depending on the application it is possible to feed off the arm, as post- or feed on the arm
  • Adjustable stand height: With a crank the working height can be adjusted exactly to suit the application
  • Different wedge sizes + different nozzle sizes and shapes
  • Several operating levels protected by passwords: If desired, the operator can only select certain operating sequences
  • Selectable languages and units of measurement
  • Heat-up and cool-down cycles possible
  • Machine can be integrated in a complete production unit


  • Tubing guide for filter tubes
  • Exhaust unit
  • Tape reel unit for taping operations
  • Double roller-arm with table
  • Hot-wedge or hot-air nozzle on the right-hand side
  • Puller (direct puller or as separate unit)
