Abstract

A panel for tensioning fabric such as a silkscreen mesh is described. The panel includes locking strips secured to the edges using stitching through the mesh and locking strips. A method for fabricating the panel and tensioning the panel on a frame is also described. Locking strips may be stitched to edges of the fabric or mesh.

Claims

1. A screen-printing panel for mounting on a frame, the panel comprising:

a rectangular mesh having four substantially straight edges, each edge of the printing panel comprising;

a semi-rigid, flexible locking strip disposed along the edge of the printing panel, the mesh folded around an edge of the locking strip to dispose the folded mesh adjacent two surfaces of the locking strip; and

a length of stitching sewn through the locking strip along a longitudinal axis of the locking strip and through two opposing surfaces of the mesh adjacent the locking strip, the stitching configured to secure the mesh to the locking strip during insertion of the locking strip into a locking strip groove of a frame and during application of tension to the printing panel, the semi-rigidity of the locking strip configured to retain the respective edge of the printing panel within the locking strip groove while the printing panel is under tension.

2. The screen-printing panel of claim 1, further comprising an adhesive configured to secure the mesh to the locking strip during sewing and during folding of the mesh around the edge of the locking strip before sewing.

3. The screen-printing panel of claim 2, wherein the adhesive is disposed on two sides of a length of tape, one side of the length of tape secured to the locking strip, the other side of the length of tape secured to the mesh.

4. The screen-printing panel of claim 1, wherein the locking strip is configured to flex along the longitudinal axis of the locking strip during insertion of the edge of the locking strip into a locking strip groove of a frame.

5. The screen-printing panel of claim 1, wherein the stitching includes an upper stitching penetrating the locking strip and securing the mesh to a first surface of the locking strip and a lower stitching securing the mesh to a second surface of the locking strip.

6. The screen-printing panel of claim 1, wherein a length of the edge of the printing panel is greater than a length of the locking strip.

7. The screen-printing panel of claim 1, wherein the locking strip is a semi-rigid, flexible plastic.

8. The screen-printing panel of claim 7, wherein a cross section of the locking strip is rectangular.

9. The screen-printing panel of claim 7, wherein a cross section of the locking strip is triangular.

10. The screen-printing panel of claim 9, wherein the fold of the mesh around the locking strip is around a wide edge of the triangular cross section.

11. The screen-printing panel of claim 1 made by:

cutting a mesh into a rectangular panel having four substantially straight edges and for each edge;

disposing a semi-rigid flexible locking strip along the edge of the mesh;

folding the edge of the mesh around an edge of the locking strip to position the a first and second portion of the mesh adjacent a first and second surface, respectively, of the locking strip; and

sewing the mesh to the first and second surfaces of the locking strip using stitching, the stitching sewn through the first portion of the mesh, the locking strip, and the second portion of the mesh.

13. The screen-printing system of claim 11, further comprising a rectangular frame having four sides, each side including a locking strip groove disposed along a length of the side, each locking strip securing the mesh against the tension within a respective locking strip groove.

12. A screen-printing system comprising:

a rectangular mesh having four substantially straight edges, each edge of the printing panel comprising;

a semi-rigid, flexible locking strip disposed along the edge of the printing panel, the mesh folded around an edge of the locking strip to dispose the folded mesh adjacent two surfaces of the locking strip, and

a length of stitching sewn through the locking strip along a longitudinal axis of the locking strip and through two opposing surfaces of the mesh adjacent the locking strip, the stitching configured to secure the mesh to the locking strip during insertion of the locking strip into a locking strip groove of a frame and during application of tension to the printing panel, the semi-rigidity of the locking strip configured to retain the respective edge of the printing panel within the locking strip groove while the printing panel is under tension; and

a rectangular frame, the screen-printing panel secured to the rectangular frame under tension.

14. A method for making a screen-printing panel, the method comprising:

cutting a mesh into a rectangular panel having four substantially straight edges and for each edge;

disposing a semi-rigid flexible locking strip along the edge of the mesh;

folding the edge of the mesh around an edge of the locking strip to position the a first and second portion of the mesh adjacent a first and second surface, respectively, of the locking strip; and

sewing the mesh to the first and second surfaces of the locking strip using stitching, the stitching sewn through the first portion of the mesh, the locking strip, and the second portion of the mesh.

15. The method of claim 14 further comprising:

applying an adhesive to a first surface of the locking strip; and

attaching the first surface of the locking strip to a first portion of the mesh along an edge of the panel using the adhesive.

16. The method of claim 15 wherein the adhesive is disposed along at least one side of a length of tape.

17. The method of claim 15 wherein the adhesive is disposed on the mesh.

18. The method of claim 14 wherein the locking strip cross section is rectangular.

19. The method of claim 14, wherein the locking strip cross section is triangular.

20. The method of claim 14, wherein the screen printing panel includes a frame, the locking strips of the screen printing panel securing the frame to the screen printing panel by:

inserting each locking strip of the screen printing panel through an entrance along the top of a locking strip groove disposed along a respective side of a rectangular frame used for screen printing;

securing each inserted locking strip within the respective locking strip groove; and

applying tension to the mesh of the screen printing panel.
