Claim 9:
10. Method of manufacturing a flat woven carpet tile, the method comprising:
providing a web of continuous flat woven carpet material, and
cutting the carpet tile from the web so that the carpet tile has three or more edges extending along a circumference of the carpet tile, the carpet tile comprising a plurality of indentations and protrusions along all edges, wherein the plurality of indentations and protrusions extend through a thickness of the carpet tile, which indentations and protrusions are shaped, dimensioned and located so that the carpet tile is adapted to be joined with abutting identically shaped carpet tiles by mutual interlocking of pairs of mating indentations and protrusions along all the edges in order to form a seamless and coherent carpet, wherein a shape of at least a substantial part of the edges includes a series of sections and no section is oriented parallel to neither the warp direction nor the weft direction, and wherein at least some of the protrusions comprise transversely extending gripping elements and the mating indentations comprise corresponding transversely extending notches, the gripping elements and notches being dimensioned so that a good interlocking is ensured even if a pulling force is applied in a plane of the carpet tiles in a direction in which the pulling force would otherwise pull the carpet tiles apart.
