Abstract
The invention concerns a method of forming a fabric of interlaced yarn by arranging on a surface a plurality of yarn guide blocks, each guide block adapted to guide yarn from a yarn source to the surface and wherein the relative motion of the yarn guide blocks and surface serves to deposit yarn from the guides onto the surface in such a way that when said yarns are deposited on a surface, the diagonal positions of the yarns from one block are offset from a direct overlapping alignment with the yarns from the remaining blocks to thereby densely cover the surface during repeated cycles of such motion.
