Method and apparatus for forming a window/door screen frame and mesh assembly without adhesive

A screen making machine comprising:

• a table;
• a welder assembly, said welder assembly comprising:
• a first hot air flow nozzle;
• a second hot air flow nozzle, said second hot air flow nozzle positioned a distance away from said first hot air flow nozzle;
• an air pump, said air pump configured to pump air through each of said first and second hot air nozzles;
• wherein said first hot air nozzle is configured and oriented to deliver a first flow of heated air;
• wherein said second hot air nozzle is configured and oriented to deliver a second flow of heated air;
• and
• a roller, said roller positioned a distance away from a side of said second hot air flow nozzle being distal from said first hot air flow nozzle;
• an actuation system, said actuation system configured to move said welder assembly relative to said table to track linearly along each side of a periphery of the frame;
• wherein during movement of said welder assembly by said actuation system at each location along the periphery of the frame, the flow of air from said first hot air nozzle elevates a temperature of the mesh and adjacent frame at each location on the periphery to a first elevated temperature, and subsequent flow of hot air from said second hot air nozzle onto the location elevates the temperature of the mesh and adjacent frame to a second elevated temperature, said second elevated temperature being above a melt temperature of each of the surface of the mesh and the surface of the frame;
• and
• wherein said roller is configured to press the melted surface of the mesh against the melted surface of the first side of the frame, to melt fuse the mesh to the frame.
