Face Mask Machine

The Facemask Machine with Elastic Ear Loop and the Facemask Machine with Tie Facemask are designed to produce ultrasonically bonded facemasks with bonded or un-bonded edges. The facemasks are usually of three-ply construction. The outer two layers are typically viscose; the inner layer is typically polypropylene.

The machine will accept up to 1-meter diameter viscose and polypropylene mill rolls. The unwind web tension on these rolls is controlled within close limits. The electronic spindle brakes are modulated by sensors, which individually monitor mill roll diameter. As the mill roll diameter decreases, braking torque decreases proportionally in order to maintain uniform web tension at the pleating station.

The pleating station consists of a series of stainless steel folding bars, which create multiple Z-shaped folds in the mask body.

The mask body then passes to an ultrasonic welding station. The mask pleats are welded into the mask body. Simultaneously, edge binders are introduced and welded to two edges of the mask body.

After the mask is welded, the material passes through a cutoff knife and is then transferred to a right angle transfer conveyor. The transfer conveyor times and places the mask into the side binding ultrasonic welding station that forms a chain of masks as the masks are passing through an elastic transfer unit and ultrasonic welder. The masks then pass through a cutoff knife that cuts both the elastic and side binding. The remaining elastic and side binding will be approximately 1/8 to 3/16 of an inch at top and bottom. After the masks are separated, a discharge conveyor collects the masks by shingling each mask until a predetermined number is counted and then indexed so the exact quantity is detectable for packing into cartons. The discharge conveyor will accumulate several index counts to allow the packer sufficient time to pack and stack cartons into shipping containers.
