Abstract: A tufted or bonded carpet tile which has an integral backing material of nonwoven synthetic fibers intermingled and/or needled together to provide comfort to persons walking on same and to reduce the noise level in areas where it is installed.

Abstract: A method and apparatus to continuously unwind fabric or material from a roll stand by splicing a new roll of material to a roll of material being unwound without interrupting the supply of material to a material consuming machine. The unwinding apparatus includes a mechanism to drop the shaft of the dissipated roll while the spliced new roll is supplied to the fabric consuming machine.

Abstract: A compact yarn distributor block mounted on the bottom of a yarn creel to direct yarn supplied from yarn packages on the creel to the point of use of a yarn processing machine, such as a texturing machine. The yarn outlet openings in the yarn distributor block are displaced vertically from one another so that the yarn from one outlet can be supplied without interference from yarn being supplied from another outlet.

Abstract: An apparatus and process to produce a spun-like synthetic yarn which employs a filament loop breaker which is periodically and automatically opened to break the vacuum pressure to allow lint collected therein to be released and collected.

Abstract: A wallcovering material having a paper backing being color and/or design printed face to which substantially parallel warp and fill yarns are tricot stitched thereto to provide an aesthetic structure through which the color and/or design shows through. The warp and weft yarns are knit to the paper backing material and held firmly in place by the polyethylene film on the face of the paper backing. The warp and weft yarns are openly spaced so that the color and/or design printed on the paper shows through and provides a pleasant view to the area in which the wallcovering is installed.
