Valv 750
Automatic machine for the production of “one way” valves for balloons.

Valv 750 is an automatic machine ideal for for making one-way valves for foil/mylar balloons to inflate with helium gas.

Valv 750 is composed of:

  • 2 independent film unwinding/reversing units with continuous control and management of tension and film centering.
  • Overlapping system for the two flaps of different films.
  • Puncher for the printed flap of the valve film only.
  • Welding plate to form balloon valve groups.
  • Two-track longitudinal cutting unit for the welded film.
  • Balloon valve winding system with two reels of maximum diameter 400 mm.

Valv 750 has a maximum useful cutting and welding distance of 750 mm.
