Adhesive tape: AT and TNN

The AT station guarantees good bonding of ink to print on the back of adhesive tape; TNN treats the back of the adhesive tape in order to avoid the so-called “noise” effect, that is the loud noise caused by the unwinding of the tape.

AT

Treatment station to be mounted on printing lines for adhesive tape or for narrow web plastic materials. It is equipped with:

  • Resin insulators
  • Multi-discharge electrodes
  • Discharge roller coated with aluminium with silicone sleeve with a diameter of 80 mm.
  • Treating width : mm. 175
  • Roll width: mm 220
  • Reading sensor speed and automatic start.

TNN

Treatment station to mount on the cutters to treat the back of the adhesive tape and to ensure the no-noise effect. Available in various sizes, it features:

  • Special system used to lift the electrodes group and with spacer rollers to eliminate contact between the discharge roller and the adhesive tape, from the adhesive side, when the machine is at rest or the corona treatment is turned off
  • Movements controlled by a specific pneumatic system
  • Ceramic electrodes
  • Very effective cooling system for electrodes, with temperatures lower than 50°C.
