High speed automatic line for the production of disposable surgical masks


Machine description:

High speed automatic line for the production of disposable surgical masks, flat laminated with three layers of non-woven fabric.
The machine is automatic and produces the masks by joining three different non-woven materials, wrapped in coils and housed on special supports.
The TNT is unwound by rollers that overlap the layers and create folds. The reinforcement for the nose is inserted inside one of these folds, then the three layers of TNT are welded by ultrasound, and cut to the correct size create the mask.
Conveyor belts carry it in correspondence with other ultrasonic welding machines that join the elastic bands to the mask body, thus completing the assembly processes. A pneumatic pusher stacks the formed masks, thus completing the automation.
Only 2 people are needed to manage the system.
