Need

Many companies have been looking to diversify their production in reaction to the COVID 19 Pandemic and the exponential demand of surgical masks. The machines utilized for the purpose have to be highly performing, reliable and compliant to the  CE standards to allow producers to respond on time to  their customers.

Petratto SKY is the result of  R&D activity to provide a productive, reliable and safe machine. All the mechanical parts are made in Italy, the electric components are made in Europe, the software has been developed and it is owned by Petratto and the machine is assembled in the factory in Pianezza (Italy)

A key priority has been security. PROTECTIONS have been conceived to 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.

Coil feeding group

4 coil holder for layered materials.
1 coil holder for nose shape support.

Coupling - welding -cutting group

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

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

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.
