PURPOSE: A screen frame for a screen printing machine is provided to improve structural strength even if external force is applied to the screen frame by forming multiple reinforcing members inside a frame body. CONSTITUTION: A screen frame for a screen printing machine comprises a frame body(10). The frame body has a hollow cross section. Two or more reinforcing members(11), composed of metal plates, are formed inside the frame body. Both ends of the reinforcing members are inserted into rails(12) formed along the inner surface of the frame body. Ribs(13a,13b) for reinforcing the strength of the frame body are protruded from the inner surface of the frame body and are touched with the reinforcing members. |
