Abstract
This invention is aimed at achieving a high-tension combination stretch screen. First, a print screen-mesh is bonded to a supporting screen-mesh at a bonding area. Then a portion of the supporting screen-mesh overlapping the print screen-mesh is removed. Then a new supporting screen-mesh is bonded to the bonding area, and again, a portion of the supporting screen-mesh overlapping the print screen-mesh is removed. Doubly fixed supporting screen meshes thus provide sufficiently increased tension to the print screen-mesh.
Claims18
A combination stretch screen, comprising:
- (a) a screen frame;
- (b) two supporting screen-meshes, each supporting screen-mesh being fixed to the screen frame;
- and
- (c) a print screen-mesh which is supported by the two supporting screen-meshes, wherein the two supporting screen-meshes at least partially overlap each other along a center portion of at least one edge of the print screen-mesh.
A production method for a combination stretch screen, comprising steps of:
- (a) attaching a print screen-mesh to a first supporting screen-mesh;
- and
- (b) attaching a second supporting screen-mesh to the print screen-mesh such that the first and second supporting screen-meshes at least partially overlap each other along a center portion of at least one edge of the print screen-mesh.
A screen print machine comprising a combination stretch screen for screen printing, wherein the combination stretch screen includes,
- (a) a screen frame;
- (b) two supporting screen-meshes, each supporting screen-mesh being fixed to the screen frame;
- and
- (c) a print screen-mesh which is supported by the two supporting screen-meshes, wherein the two supporting screen-meshes at least partially overlap each other along a center portion of at least one edge of the print screen-mesh.
A reinforcement method for an existing stretch screen wherein the existing stretch screen includes a screen frame, and a print screen-mesh supported by the screen frame, comprising steps of:
- (a) stretching a reinforcement screen-mesh on the screen frame of the existing stretch screen;
- (b) affixing the reinforcement screen-mesh to the print screen-mesh;
- and
- (c) removing a portion of the reinforcement screen-mesh where the reinforcement screen-mesh and the print screen-mesh overlap.
