1. Three or four layers fabrics (top fabric, filter fabric and bottom fabric) feeding in auto-align, sides symmetrically welding by ultrasonic, and continuously cutting to mask pieces by welding roller, then distributed to two ear-loop welding stations to improve the production efficiency. Auto mask stack counting function after ear-loop welt and side cladding.

2. Production line is 1-to-2 design. After the blank mask making machine, the blank mask will be automatically distributed to the two ear-loop welding and side cladding stations through the transmission system.

3. The ear loop is welded by ultrasonic and automatic cutting.

4. Edge cladding is automatically welding and cutting.

5. Nose clip is cutting and feeding automatically.
