Method and apparatus for forming a window/door screen frame and mesh assembly

A screen making machine comprising:

• a table;
• a welder assembly, said welder assembly comprising:
• a hot air flow nozzle configured to provide hot air;
• a roller, said roller positioned a distance away from a side of said hot air flow nozzle;
• an actuation system, said actuation system configured to move said welder assembly relative to said table along a frame;
• wherein during movement of said welder assembly by said actuation system at locations along a periphery of the frame, the flow of air from said hot air nozzle elevates a temperature of the mesh and adjacent frame to an elevated temperature, said elevated temperature being above a melt temperature of each of the surface of the mesh and the surface of a first side 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 and to heat the melted surface of the mesh and the melted surface of the first side of the frame, to melt fuse the mesh to the frame.

A screen making machine comprising:

• a table;
• a welder assembly, said welder assembly comprising:
• a hot air flow nozzle;
• an air pump, said air pump configured to pump air through the hot air nozzle;
• a roller, said roller positioned a distance away from a side of said 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 a frame;
• at least one track formed in said table;
• at least one clamp mechanism, a portion of said at least one clamp mechanism configured to travel along said at least one track to move the frame along said top surface of said table from at least the first process station to a second process station;
• 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 hot air nozzle elevates a temperature of the mesh and adjacent frame to an elevated temperature, said elevated temperature being above a melt temperature of each of the surface of the mesh and the surface of a first side 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 and to heat the melted surface of the mesh and the melted surface of the first side of the frame, to melt fuse the mesh to the frame.
