The present invention is an apparatus for forming a fabric for an architectural opening covering. The apparatus comprises a joining section, an accumulator, a cutting station, and a stacker. The joining section is configured to join together first, second, third and fourth material strips into a fabric strip. The accumulator is configured to accumulate the fabric strip upon leaving the joining section. The cutting station is configured to sever the fabric strip into an upstream fabric strip and a first downstream fabric strip. The stacker is configured to join the first downstream fabric strip with a second downstream fabric strip to form the fabric.

What is claimed is: 1. An apparatus for forming a fabric for an architectural opening covering, the apparatus comprising: a joining section configured to join together first, second, third and fourth material strips into a fabric strip where each of said material strips has top and bottom sides and front and rear edges and wherein the fabric strip has the top side of the rear edge of said first material strip secured to the bottom side of the front edge of said second material strip, said second material strip has the bottom side of its rear edge secured to the top side of the rear edge of said third material strip and the fourth material strip has the top side of its front edge secured to the bottom side of the rear edge of said third material strip; an accumulator configured to accumulate the fabric strip upon leaving the joining section; a cutting station configured to sever the fabric strip into an upstream fabric strip and a first downstream fabric strip; and a stacker configured to join the first downstream fabric strip with a second downstream fabric strip to form the fabric. 2. The apparatus of claim 1, wherein the joining section comprises first, second, third and fourth rollers for holding, respectively, rolls of the first, second, third and fourth material strips. 3. The apparatus of claim 1, wherein the joining section comprises a joining roller about which the first, second, third and fourth material strips are joined together to form the fabric strip. 4. The apparatus of claim 3, wherein the joining section comprises a glue station for applying a glue bead to the first material strip prior to said strip encountering the joining roller. 5. The apparatus of claim 3, wherein the joining section comprises a glue station for applying a pair of glue beads to the second material strip prior to said strip encountering the joining roller. 6. The apparatus of claim 3, wherein the joining section comprises a glue station for applying a glue bead to the fabric strip upon leaving the joining roller. 7. The apparatus of claim 1, wherein the cutting station comprises an air jet nozzle for applying a flow of air against the fabric strip. 8. The apparatus of claim 7, wherein the cutting station further comprises a knife and a knife block, and the flow of air maintains the fabric strip against the knife block. 9. The apparatus of claim 1, wherein the stacker comprises a vacuum belt for transporting the first downstream fabric strip. 10. The apparatus of claim 1, wherein the stacker comprises an elevator for bringing the second fabric strip into contact with the first fabric strip. 11. The apparatus of claim 1, wherein the stacker comprises a pin rack for impaling the fabric strips together as they bond to form the fabric. 12. A method of forming a fabric for an architectural opening covering, the method comprising: joining together first, second, third and fourth material strips into a fabric strip where each of said material strips has top and bottom sides and front and rear edges and wherein the fabric strip has the top side of the rear edge of said first material strip secured to the bottom side of the front edge of said second material strip, said second material strip has the bottom side of its rear edge secured to the top side of the rear edge of said third material strip and the fourth material strip has the top side of its front edge secured to the bottom side of the rear edge of said third material strip; accumulating the fabric strip as the fabric strip leaves the joining section; severing the fabric strip into an upstream fabric strip and a first downstream fabric strip; and stacking the first downstream fabric strip with a second downstream fabric strip to form the fabric. 13. The apparatus of claim 10 wherein the bottom side of the front edge. of said third material of said first fabric strip is secured to the top side of the front edge of said second material strip of said second fabric strip in said stacker. 14. The method of claim 12, further comprising providing the first, second, third and fourth material strips, respectively, on first, second, third and fourth rolls. 15. The method of claim 12, further comprising joining the first, second, third and fourth material strips about a joining roller to form the fabric strip. 16. The method of claim 15, further comprising applying a glue bead to the first material strip prior to said strip encountering the joining roller. 17. The method of claim 15, further comprising applying a pair of glue beads to the second material strip prior to said strip encountering the joining roller. 18. The method of claim 15, further comprising applying a glue bead to the fabric strip upon the fabric strip leaving the joining roller. 19. The method of claim 12, further comprising applying a flow of air against the fabric strip. 20. The method of claim 19, wherein the flow of air maintains the fabric strip against a knife block. 21. The method of claim 12, further comprising transporting the first downstream fabric strip via a vacuum belt. 22. The method of claim 12, further comprising elevating the second fabric strip into contact with the first fabric strip. 23. The method of claim 12, further comprising impaling the fabric strips together as they bond to form the fabric. 24. The method of claim 22 further including the step of securing the bottom side of said front edge of the third material strip of said first fabric strip to said top side of said front edge of said second material strip of the second fabric strip when said second fabric strip is elevated into contact with the first fabric strip.
