Coil feeding group (1)
- 4 coil holder for layered materials.
- 1 coil holder for nose shape support.
Security protections – CE STANDARD
- PROTECTIONS prevent access to dangerous areas of the machine.
- All the moving parts of the machines which could constitute a danger are protected by fixed or movable guards locked to prevent accidental contact and avoid damage.
Coupling – welding -cutting group (2)
- Coupling of material layers.
- Inserting the nose shape support, with the possibility of adjusting the length of the insert.
- Ultrasonic welding, via sonotrodes, longitudinal edges (long side of the mask).
- Mechanical folding (concertina type).
- Ultrasonic welding, via sonotrodes, transversal edges ( short side of the mask).
- Cut to size of the mask.
- Deposit on sectoral channel for deflect 90 ° the single mask.
Sorting group with 3 outputs (3)
- Motorized “channel” with sectors.
- 2 alternating pneumatic pushers for sending the masks to the supply channels for the next step.
- 3rd exit for emergency (if one machine for ear strap is stopped, the other one continues the operation).
This Solution allows a compact footprint of the machine.
n°2 line to cut / form / weld the ear strap (4-5)
- Channel / belt reception of single masks.
- Ear strap feeding.
- Legth cutting with preparation and insertion.
- Ultrasonic welding, using sonotrodes (it is used to melt the strap on the inside of both ends of the mask body).
- Single mask collection on belt.
