| 261 | Paper machine fabric | US514447 | 1990-04-25 | US4982766A | 1991-01-08 | Seppo Taipale; Merja Hakkarainen |
| A two-layer paper machine fabric comprising a machine direction yarn system and two cross-machine direction yarn systems, the systems being interlaced in accordance with a 16-shaft weave repeat. To achieve a fabric having advantageous wear properties, the lower cross-machine direction yarn forms floats spanning 13 yarns on the underside of the fabric and is interwoven in the fabric by passing it during one weave repeat over two machine direction yarns positioned close to each other in such a way that at least one machine direction yarn remains between said two machine direction yarns, said at least one machine direction yarn passing over the lower cross-machine direction yarn. The upper cross-machine direction paper-contacting yarn forms floats of shorter span as compared with the lower cross-machine direction yarn on the upper side of the fabric and is interlaced with at least two machine direction yarns per weave repeat. | ||||||
| 262 | Paper making fabric having a reduced permeability profile | US653560 | 1984-09-24 | US4649964A | 1987-03-17 | Richard W. Smith |
| A woven paper making fabric (A) is disclosed having a profiled permeability characteristic which varies across the width of the fabric yet the tensions are relatively uniform across the width of the fabric. The fabric includes a plurality of warp yarns (20, 22, 24, 26) extending in a machine direction and a plurality of weft yarns (28, 30, 32) extending in a cross-machine direction in the fabric woven with the warp yarns. The weft yarns and warp yarns are woven to provide at least two layers (60, 62, 64) in the fabric. A number of unwoven fabric closure elements (B) are bound between the weft yarns of two of the fabric layers (60, 62) extending in the machine direction adjacent the lateral edges (42, 44) of the fabric (A). The closure elements (B) extend through the fabric parallel to the edges in a generally straight configuration between the two fabric layers (60, 62) in a generally tensionless state so as not to effect the tension of the weave of the fabric. A uniform weave tension exists across the width of said fabric. The closure elements block the flow of air through the fabric to reduce the permeability of the fabric at the lateral edges (46, 48) and provide the desired permeability profile. | ||||||
| 263 | Fabric having a reinforced warp strip and a process for producing the same | US870628 | 1978-01-19 | US4143679A | 1979-03-13 | Paul Luber |
| The fabric is woven with a reinforced warp strip between the background section and the selvage to allow spreading out of the fabric without using needle rollers in the background section. The reinforced warp strip may be formed with a permanent strip portion which remains with the background section and a removable reinforced strip portion which can be severed from the fabric. | ||||||
| 264 | Preformed cross-laid fabric and method of manufacturing the same | US35686173 | 1973-05-03 | US3860045A | 1975-01-14 | WORCESTER JR BEN C; WATSON DOMA A |
| A fabric comprising from about 2 to 8 yarns per inch running in the transverse or cross direction of the fabric and a selvage along each longitudinal edge of the fabric. Each selvage comprises from about 10 to 30 warp yarns and has a width of from 1 inch to 3 inches. The warp yarns in the selvage being woven with the cross yarns and the warp yarns having a denier of from about 70 to 300. The fabric is made by drawing a plurality of selvage warp yarns through each side of a loom while maintaining the yarns under tension. As the warp yarns are drawn through the loom the cross yarns are woven with the warp yarns to form the selvage. As each cross yarn is woven the selvage is held in place. The selvage is released and the fabric moved forward and regripped and the next cross yarn woven, and so forth. After the cross yarns are woven to form the selvages, tension is applied to the fabric in the crosswise direction and the fabric rolled on a driven roll.

| 265 | Antimicrobial woven or knitted fabric | US3699958D | 1970-12-31 | US3699958A | 1972-10-24 | SZUCS LASZLO G |
| An antimicrobial woven or knitted fabric which is made from crimp yarn and treated with cation-active antimicrobial compounds and the use of said fabric as surgical dressing or surgical face mask.

| 266 | Method of producing a self-gripping fastening filament | US3655855D | 1970-05-08 | US3655855A | 1972-04-11 | BRUMLIK GEORGE C |
| A method is provided to produce a self-gripping fastener device which is integrally made as part of a thread or filament. A sheet of plastic is extruded having the profile of a series of hooks extending therefrom spatially staggered along the length of the sheet. The sheet is then cut into thin sections to form threads or filaments. The device is then employed either as a filament or as a yarn to form a fabric, felted surface or the like, the latter being releasably self-adhering by the application of pressure therein.

| 267 | Method of making a bias weave honeycomb core structure | US3598676D | 1968-07-25 | US3598676A | 1971-08-10 | NOBLE ROBERT G |
| A HONEYCOMB CORE STRUCTURE MADE OF FABRIC REINFORCED MATERIAL IN WHICH THE WARP AND THE WOOF OF THE FABRIC ARE DISPOSED AT AN OBLIQUE ANGLE TO THE LONGITUDINAL AXES OF THE HONEYCOMB CELLS. THE CORE IS MANUFACTURED BY FORMING NON-RECTANGULAR PARALLELOGRAM SHAPED SECTIONS OF FABRIC REINFORCED MATERIAL WITH THE WARP AND THE WOOF OF THE FABIRC BEING DISPOSED AT AN OBLIQUE ANGLE TO TWO SIDES OF THE PARALLELOGRAM, JOINING THE OTHER TWO SIDES OF ADJACENT PARALLELOGRAMS TOGETHER IN SERIAL RELATIONSHIP TO FORM A WEB IN WHICH THE WARP AND WOOF OF THE FABRIC ARE DISPOSED AT AN OBLIQUE ANGLE TO THE LATERAL EDGES OF THE WEB, CUTTING THE WEB AT RIGHT ANGLES TO ITS LATERAL EDGE TO FORM EQUAL RECTANGULAR SECTIONS, SUPERIMPOSING A PLURALITY OF RECTANGULAR SECTIONS ONE UPON ANOTHER IN A STACK, AND OVERLAPPING AND ADHERING CONTIGUOUS EDGES OF THE RECTANGULAR SECTIONS TO ONE ANOTHER ALONG SPACED PARALLEL BONDING LINES WITH THE BONDING LINES OF ADJACENT SUPERIMPOSED SECTION BEING STAGGERED RELATIVE TO ONE ANOTHER TO DEFINE A PLURALITY OF ADJACENT CELLS WHOSE LONGITUDINAL AXES ARE PARALLEL TO EACH OTHER AND PERPENDICULAR TO TWO SIDES OF THE SUPERIMPOSED RECTANGULAR SECTIONS.

| 268 | Fabric having integral and sectional weft threads, and loom for making the same | US3556165D | 1968-12-23 | US3556165A | 1971-01-19 | ZMATLIK JOSEF; JISA MILOSLAV; SEDLECKY JAROMIR; MATEJKA JOSEF; MOHELNICKY JOSEF; MILICHOVSKY BOHUMIL |
| A fabric is woven of warp threads crossing integral and sectional weft threads which alternate. The integral weft threads extend across the entire fabric and are inserted by first weft inserting means, while each sectional weft thread includes a plurality of aligned double weft elements which are inserted into warp shed sections, respectively, by a plurality of weft inserting needles, and preferably tied by a knitting needle.
