588,548. Pile fabrics. FUHRHOP, W. F., and ISSUM, H. VAN. March 1, 1945, Nos. 5111, 20412, 21704 and 28467. [Class 142 (iv)] A method of manufacturing a pile fabric of determined density having a texture simulating woven pile fabric, comprises arranging yarn on rods or other supporting members in determined spaced relation to suit the weftwise density, assembling the yarn on the supporting members to suit the warpwise density, consolidating the suspended yarn by means of a consolidating medium, e.g., a water-soluble solution or gel forming transverse sections of the consolidated yarn, removing sufficient of the consolidating medium of each section to expose yarn ends, fixing the exposed yarn ends in a backing, e.g., of plastic, and removing the remainder of the consolidating medium. The backing may, however, be applied to the ends of the yarn before each section is cast off. In one form, Fig. 2, the yarn 12 assembled on bars 8 is placed in a mould 10 and consolidated by a solidifying medium 11 to form a block which is removed from the mould and cut transversely into sections to each of which a backing is secured. The yarn may be assembled with the aid of jacquard or other shedding mechanism or by winding yarn on a number of frames. In a modification, the assembled yarn is placed in a sectional mould and the consolidating medium inserted in the mould to form successive layers. In another modification, the yarn is impregnated with consolidating medium while it is being assembled. In a further modification, the finished fabric sections are combined to form a length of fabric, or a carpet or rug. In a still further modification, two sections of consolidated yarn are superposed with backing material between them. |
