Claims14
In a respiratory face mask manufacturing machine including a series of wheels, connector mechanisms, and transfer mechanisms adapted to form respiratory face masks, the improvement comprising:
- an impression wheel including:
- a main cylindrical body including:
- a length;
- a width;
- a perimeter;
- a central axis;
- a proximal end section;
- a distal end section;
- and
- an outer surface;
- wherein said outer surface extends along said length and around said perimeter of said cylindrical body;
- a first series of spaced helicoidal teeth, each including:
- a whole depth;
- a face width;
- and
- a top land;
- wherein said first series of spaced helicoidal teeth are formed having a slanted tooth trace;
- and
- wherein said first series of spaced helicoidal teeth extend from and around said perimeter of said proximal end section of said outer surface of said main cylindrical body;
- a second series of spaced teeth, each including:
- a whole depth equal to said whole depth of said first series of spaced teeth;
- a face width;
- and
- a top land;
- wherein said second series of spaced helicoidal teeth are formed having a slanted tooth trace equal to said first series of spaced helicoidal teeth;
- and
- wherein said second series of spaced helicoidal teeth extend from and around said perimeter of said distal end section of said outer surface of said main cylindrical body;
- and
- a third series of spaced teeth, each including:
- a whole depth equal to said whole depth of said first series of spaced teeth;
- a face width;
- and
- a top land;
- wherein said third series of spaced helicoidal teeth are formed having a slanted tooth trace equal to said first series of spaced helicoidal teeth;
- and
- wherein said third series of spaced helicoidal teeth extend from and along a substantial portion of said length of said main cylindrical body, and extend between said first and second series of spaced helicoidal teeth;
- wherein said impression wheel is adapted to press and interconnect together four side portions of respective layers of said respiratory face masks.
