The common and prevalent practice of producing fabric floor coverings Gerald E. Herrastadt, Cornwall, N.

The foregoing and other objectives and advantages of this invention will be more clearly understood from the The present invention relates to Axminster and following detailed description of illustrative embodi has for its object the provision of a three-shot Axminster ments thereof, when taken in conjunction with the ac Weave of novel construction with particular advantages. companying drawings, in which: - The principal object of the invention is to provide a Fig. 1 is a warpwise section of a three-shot Axminster modified form of Axminster weave in which a warp end weave with cut pile; of suitable material is so tensioned and arranged as to. Fig. 2 is a table of heddle positions for the run together with or parallel to the chain warp so as to cycle utilized in producing the fabric of Fig. 1; - permit the loop portions of the pile tufts to come through Fig. 3 is another warpwise section of a fabric embody the back in a manner easily achieved on standard ing the weave construction of this invention modified as Axminster looms. to the position of the pile tufts; in common with Axminster weaves, the modification 25 Fig. 4 is a table of heddle positions of the weaving of this invention involves the use of three double weft cycle used in producing the fabric of Fig. 3; and shots to one face row, but differs therefrom in that pairs Fig. 5 is a modification of the weave construction of of double weft shots are bound under two warp ends Fig. 3 in which the warpwise section has been varied only extending together, and above a single warp end, with the by substitution of pile tufts with legs of unequal height. pile tufts preferably looped under a double weft shot of 30 The weave of Fig. 3 is the preferred embodiment of the each pair of such shots, or alternatively under the single invention, for reasons which have been mentioned and double weft shots intermediate said pairs. will be more fully explained.
