  • Special cutting system with scrap extractor to cut off the corner of the pouch in preparation for the insertion of the spout
  • Vibratory bowls with independent channels connected to a step-by-step feeding system
  • High precision spout introduction system
  • Valve positioner
  • Special sealing system for corner spouts
  • Special top sealing system adapted to the pouch format
  • Special opening system for pouches with corner spout
  • Pouch opening detector at the station of spout insertion

Top Spout

The top cap applicator is composed of:

  • Vibratory bowls with independent channels connected to a step-by-step feeding system
  • High precision spout introduction system
  • Valve positioner
  • Special sealing system for top spouts
  • Special top sealing system adapted to the pouch format

Frontal Spout

The ultrasonic front cap application system is located in the unwinder. The cap is applied while the film is flat, prior to pouch formation. This system is composed of:

  • Vibratory feeding system for front spouts (the feeder can be easily adjusted to suit each pouch format)
  • A special film pulling system consisting of a group of servo motorized rollers synchronized with a photocell to ensure the correct position of the cap
  • A hole punching device to make the hole where the plug will be sealed (the device can be easily adjusted for a format change)
  • A spout applicator aligned with the hole punching device, to correctly accommodate the cap
  • A group of ultrasonic sealing system to weld the cap to the film (the use of an ultrasonic system guarantees the absence of leaks)
  • Front spout detector that sends a signal not to fill the envelope in case the spout is improperly placed (occurs after synchronization with the dosing system)
  • The Customer will have to indicate brand, model, and reference of the cap.

Straw Application

The straw feeding system consists of a frame with independent protections. In this structure, there is a special hopper for straws that is connected to a step by step system, which guides the straw to the introduction funnel.
Once the straw is introduced, a special jaw makes a small welding point to fix the straw inside the pouch and prevent it from floating during the filling of the product, thus avoiding problems in the top seal.
This system includes an automatic correction device to insert the straw correctly into the pouch, and allows for a rapid adjustment, in case a format change is required.
