The fully automatic mask machine consists of three machines, one mask machine and two sets of ear-loop sealing machines.  There are automatic belt conveyor and wiring machine added. Compared with semi-automatic machine, this design not only improves the production efficiency, but also reduces labor work and cost. The whole line works automatically from feeding, nose line inserting, edge sealing, mask cutting, two ear-loops welding, packing, till the end. Only one worker is enough for the whole operation.
