Abstract: A pressure sensitive tape composed of a polyethylene base film; a continuous filament scrim fabric having a fiberglass fill yarn and a pressure sensitive adhesive applied to the film through the substrate.

Abstract: Method to produce a roofing membrane for use in the construction of roofs which comprises mating of at least two plys of fiberglass scrim fabric to form a substrate for the roofing membrane. At least one of the plys of the substrate is a triaxially wound scrim fabric to provide additional strength to a standard open mesh rectangular formed scrim fabric.

Abstract: A single ply convertible top fabric comprising a sateen woven fabric using a blend of solution dyed polyester and cotton yarn coated with a PVC vinyl.

Abstract: In a method for keeping an easily removable mat or similar small carpet (5) in place in a carpeted or carpet tile covered area (1) of a floor, the mat (5) is provided with a pattern of engageable means, such as projections (6), distributed all over its lower side. One or more parts (2) of the floor area (1) to be covered by the mat (5) is kept or made free from carpeting or carpet tile covering, and said one or more uncovered parts (2) of the floor area (1) is provided with an anchoring plate material (7), the upper surface of which is performed with engageable to engage the lower side of the mat (5) for preventing a horizontal displacement of the mat. Then the mat (5) is arranged in place for covering the anchoring plate material (7) and for engagement between its lower side and the upper surface of the anchoring plate material (7). Thereby is obtained that the mats may be easily replaced and no risk occurs for the people walking on the carpeted area (1) during the replacement.

Abstract: A method and apparatus to measure the loop height in a loop pile fabric by moving an apparatus across the surface of the fabric and allowing the loops to create a line on a powdered surface to which a finger is aligned with to cause the plunger of a gauge to automatically provide a read-out of the loop pile height.

Abstract: Method for dyeing a cotton nap fabric or carpet wherein the dyestuffs belong to a group of vat dyestuffs and reactive dyestuffs and are applied to the cotton nap. The product after the application of the dyestuff is treated with a uniform application of a liquid agent from a group of agents which are able to make the selected dyestuff absorbable by cotton.

Abstract: Method and apparatus to surface treat a web of fabric by passing it over and in contact with a rotating tungsten carbide coated roll. The selvedges of the web of material are held on rotating members with pins on the periphery thereof which penetrate the fabric.

Abstract: Method to produce a roofing membrane for use in the construction of roofs which comprises mating of at least two plys of fiberglass scrim fabric to form a substrate for the roofing membrane. At least one of the plys of the substrate is a triaxially wound scrim fabric to provide additional strength to a standard open mesh rectangular formed scrim fabric.

Abstract: An ultra-sonic weaving machine reed cleaner in which the cleaner is moved adjacent the weaving machine and the reed is cleaned without disturbing the thread-up of the warp yarn in the reed. The reed cleaner consists of three bins in which the reed consecutively is placed to wash it, rinse it and then blow it dry. A plurality of transducers are placed in contact with the bottoms of the washing and rinsing bins to enhance the action of the washing and rinsing fluid.

Abstract: Apparatus and method to provide sealed edge products with a reduced tendency to lint and ravel by supplying a hot air jet in the range of 600.degree.-800.degree. F. to melt and swell the fibers to lock the warp yarns in the fabric. The hot air jet is directed perpendicular to the warp yarns and parallel to the fill yarns in the sealed edge product.

Abstract: A printing blanket having a printing face, a compressible body of material below the printing face and at least one body or reinforcing layer adjacent the compressible layer. The reinforcing layer is a woven fabric having air textured polyester warp and fill yarns therein.

Abstract: Method for press vulcanizing, not only of dry, wholly or partly vulcanizable articles (1), such as auto rubber mats, piled rubber mats, etc., of a humidity of 0-3 weight percent but also of such articles (1) of a humidity of 3-5 weight percent or more, in the press zone of a vulcanizing press (P) having a shiftable part for closing and opening of the press (P) capable of applying a uniform surface pressure against any article (1) fed into the press. In that at least from the beginning of the vulcanizing operation to the end of it, a multitude of flow routes is established between the press shiftable part and each article (1) for vapors and gases released from each article (1), and a multitude of flow routes out from the press zone from where said vapors and gases may thus escape at least along part of the border of said press zone border, a method is brought about in which no vulcanizing heat is lost for heating of confined vapors and gases at high pressures.

Abstract: A pressure sensitive tape employing a tricot knit carrier fabric having a minimum number of weft yarns. The tricot knit carrier fabric being knit on a tricot knitting machine which employs a loop hold down bar to prevent the first three or four courses adjacent the needles of the knitting machine from breaking out when released or cast off the needles.

Abstract: The method of providing an impression fabric in which the fill yarns do not protrude from the plane of the fabric. The impression fabric is a tubular woven fabric in which a plurality of warp yarns is woven in one edge thereof and dissolved by washing after the fabric has been formed.

Abstract: A method to form a carpet tile into a configuration for use on a stair riser. This method involves measuring the stair riser and using this measurement to score the pile on the face of a tile. The tile is then bent to a 90 angle and a nose guard adhesively placed over the bent or nose portion of the title to provide a preformed product. This product then can be taken on the job, placed into position and readily tacked or glued down to provide the stairs with a tile product which is comparable to the adjacent tiled areas and readily tacked or glued down to provide the stairs with a tile product which is comparable to the adjacent tiled areas.

Abstract: Method and apparatus to produce a plied, air textured continuous filament yarn by severing the supply yarn upon the detection of a drop in tension. When the tension in the yarn being processed drops, the position of the running yarn will be detected by a photocell unit which will actuate a cutter upon such detection to sever the yarns being supplied to the air texturing machine. The method and apparatus provide that the drop in tension has to occur for a predetermined length of time or occur a multiplicity of times before the cutter is actuated.
