'Y., assignor to Bigelow-Sanford Carpet (30., Inc., Thomp sonville, Conn, a corporation of Massachu setts Application January 28, 1937, Serial No. 122.45% 10 Claims. (Cl. 139-391) This invention relates to pile floor coverings same weight and mix but may have more plies and particularly to an improvement in the con struction of fabrics of that type, wherein the areas normally subjected to greatest wear are made more highly resistant to wear. In use, certain areas of ?oor coverings are commonly subjected to more wear than other portions. Thus the borders of the rug or car peting are usually subjected to more wear than 10 the body portions. Where imitation broadloom carpeting is made fro‘in assembled strips of nar row carpeting, the seam produces a ridge which usually wears away more rapidly than the re _ mainder of the carpet.‘ I” ' It is the primary object of the present inven tion to increase the life of rugs and carpets and I have found that this may be accomplished at comparatively small cost by increasing the sturdi ness of the rug at the borders, seams, or other 20 portions which are subjected to the greatest wear. In the preferred embodiment of my in vention I attain this object by providing a more durable pile in those portions such as by em ploying a more serviceable yarn or by increasing 25 the count of pile tufts in those portions. How ever, as will appear, an increase in the strength or thickness of the warps and wefts of the back ing fabric is also effective for my purpose. These and further objects and advantages of 30 my invention will appear from a more .detailed description thereof in connection with the ac companying drawing in which:— Fig. 1 is a perspective view of a preferred em bodiment of my invention, shown as incorporated 15 ‘UK into an Axminster rug; Fig. 2 is a detail sectional view showing my in vention as embodied in the seamed portions of assembled carpet strips, and Fig. 3 is a perspective view of a modi?ed form 40 of my invention ‘as embodied in an Axminster rug. In Fig. II have illustrated an Axminster rug I of any suitable weave, having a body portion 2, an end border portion 3 and a side or selvage border portion 4. The pile 5 of the main body 4-5 portion 2 is composed of yarn of any suitable grade. weight, twist, etc. for a rug of the desired speci?cations. The border portions 3 and 4 are composed of pile tufts l0 and in accordance with my preferred embodiment, the yarn from which 50 the tufts I0 is made possesses greater wear re Isisting qualities than the yarn employed in the tufts 5. Thus, for example, the border tuft yarn may be a heavier yarn or it may have a different is blend of wool conducive to greater resistance to 5 abrasion. On the other hand, it may be of the or a greater twist. In weaving a rug of the Axminster type, the change in pile yarn from that used in the body portion 2 to that used in the border sections 3 5 and 4 can readily be accomplished when the tube frame spools are being wound. Thus for the selvage border portions 4, yarn of the special characteristics above noted is wound on the ends of the spools and threaded through the end 10 tubes in the tube frames. To weave the end border portions 3, the entire tube will be threaded with yarn of those characteristics. In rugs of the Wilton type, the insertion of the special pile yards in the end and side border 15 sections can also be readily accomplished; Thus for the selvage border portions, the desired qual ity of yarn is carried as pile warp through the end interdental reed spaces, and to provide the end border sections 3, the stronger pile warp may be carried on a separate beam and raised out of the backing fabric by suitable jacquard mech anism. As a modi?cation of my invention I may em ploy the same yarn for the tufts l0 as is used for 25 the tufts 5 and effect an increase in resistance to abrasion in the side and end' borders by em ploying a greater number of pile tufts per unit of area in those portions than in the body por tion. By decreasing the fabric take-up at the. 30 breast beam, the rows of pile in the end border sections 3 can readily be increased. Additional rows may be inserted in the side border portions 4 by suitably constructing andvspacing the tuft inserting or raising mechanism depending upon 35 the type of loom employed. } Of course, a still further increase in wearing ' qualities can be effected by combining an in crease in pile tuft count with an enhancement in yarn grade as above described. 40 As a further modi?cation the present inven tion contemplates that the enhanced wearing characteristics may be obtained by employing heavier warp and/or weft yarns or threads in the marginal portions of the backing fabric than in 45 the body portion thereof. Such a construction is shown in Fig. 3 wherein the tuft pile yarns 30 in the end and side border portions may or may not be of the same general weight or character as those in the main body portion 3!. 50 In the construction of Fig. 3 the end border section 33 is constituted of weft yarns 34 which are of heavier and preferably thicker character than the weft yarns 35 which extend through the body portion of the rug and likewise the warp 55 2,105,780 yarns 38 along the side border 31 of the rug are border areas outside said body portion, said of heavier and preferably thicker character than k border areas being provided with yarns that are the warp yarns 38 which go to make up the body heavier than the corresponding yarns of said portion of the rug. body portion so that the tread surface of said ' border areas is more highly resistant to' abrasive. 5 s The effect is that the heavier warp and/or weft yarns of the ' marginal portions will im part to the border sections increased wearing qualities, partly by more closely compacting the pile tufts at those portions and thereby making 10 them more highly resistant to wear. In Fig. 2 I have illustrated a portion oi’ carpet ing constructed of assembled strips 20 and 2i secured together in any suitable manner such as by an adhesive tape or by stitching as indicated 15 at 23. In manufacturing strips of carpeting so to be assembled, the pile tufts 22 and 23 at and adjacent the abutting edges are so constructed as to resist wear better than the tufts 20 and 2| of the remainder of the rug strips and such con 20 struction may be in accordance with any of the above described embodiments of my invention. The rug when sewn together by the stitching 23, and/or taping if desired, will be more resistant to wear at the seam portions than the common seamed rug having pile which is uniform wear tending to shorten the pile than the tread surface of said body portion, whereby to enhance the wearing qualities of said border areas. .

This may readily be accomplished by 85 threading the tube frames of Axminster looms or the reeds of Wilton looms‘ with yarn which is graded in weight to .become progressively heavier as the borders are approached. .
