The textile layer (1) includes tufts containing cotton fibres, and the backing layer (2) is made of a foamed elastomer material and includes a plurality of cleats (4) on a lower surface if the backing layer.

Abstract: A washable floor mat has a tufted pile textile surface (1) and an elastomer backing layer (2). The textile surface (1) includes tufts of a blended yarn that includes at least 40% cotton fibers and at least 25% polyester fibres. The cotton and polyester fibres together comprise at least 90% of the total fibre content of the blended yarn.

Abstract: The present invention relates to specific methods of producing cleated rubber-backed floor mats (such as dust control or rubber mats) through the utilization of the combination of a perforated coated woven fabric article and a cushioned platen liner between the article and the metal platen of an in-line dust control mat manufacturing machine. Such a procedure permits a more efficient manner of producing cleated anti-creep dust control mats than previously followed. In particular, the fabric article is in the form of a conveyor belt and is preferably constructed from Teflon®-coated woven fiberglass which will not adhere to the tacky rubber component of the target mat and can withstand the extremely high vulcanization temperatures and pressures required during the production of a dust control mat.

Abstract: A yarn for a floor textile material which is comprised of a coarse yarn and a fine yarn twisted together for tufting into a backing material to provide a floor mat. The finer yarn has fibers in the range of 32 to 100 decitex while the coarser yarn has fibers in the range of 110-290 decitex.

Abstract: A washable, water and dust binding service mat having a nap and a rubber or plastics backing layer, whereby the nap and a woven ground fabric for the tufting is fastened in the backing layer material, the ground fabric for the tufting comprising a layer of woven primary fabric of synthetic split fibers being calendered together by a heat setting operation with a layer of a nonwoven fiber fleece which prior to this heat setting operation has been needled together with the woven primary fabric by a needle technique. The nonwoven fiber fleece has an area weight of 80-150 grams/m.sup.2, consists of two or more kinds of synthetic fibers, with one having a softening temperature lower than the other synthetic fiber.

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: 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: In a sealing system for a diaphragm type vulcanizing press, the diaphragm (19), having a roundgoing fixing flange, applies the necessary compression moulding pressure during the vulcanizing press operation, and along its edge the diaphragm is attached to a fixing flange (10) on one of the press parts through a number of fixing devices mounted round along the diaphragm (19) edge, fixing a roundgoing frame (12) against the diaphragm (19) for the sealing of same against the press fixing flange (10).

Abstract: In that a vulcanized rubber article (8), preferably of sheet or plate form and preferably having a relief pattern, in at least part of its surface, integrated in any surface area, inserted or settled into same, has been provided and vulcanized together with a rubber material (6) in the form of letters, signs, and digits in at least one color deviating from the rubber article (8) color composition, and that the rubber material (6) has a vulcanizing temperature range matching that of the rubber article (8), a hardwearing and washproof as well as distinct marking of the rubber article is obtained. A label to be used for the marking of the rubber article consists of a foil material (10) of a thickness of 10-100 micron upon which using a printing ink (11) of rubber material inverted text, figures and/or pictures have been printed.

Abstract: Through a method for production of piled mats (1-3) with rubber backing on a vulcanizing press (P) with a stationary vulcanizing heater plate (8) where articles (1-3) to be vulcanized are conveyed into position in and out of the press (P) from one and the other side of it using a heat conducting conveyor belt (9), each of the vulcanized articles (1) will be conveyed as soon as it leaves the press (P) on the conveyor belt (9) after the press vulcanizing operation to one of two cooling and degassing stations (KA1, KA2) while at the same time a next unvulcanized article (2) is conveyed on the same conveyor belt (9) into its position in the press (P) while said next article (2) is conveyed after the press vulcanizing operation to the second of the two cooling and degassing stations (KA1, KA2) while at the same time a next unvulcanized article (3) is conveyed on the conveyor belt (9) into its position in the press (P) in connection with which each article at the cooling and degassing stations is removed after the

Abstract: A floor covering such as a nap mat or carpet of washable type comprises a rubber or plastic back, wherein the nap or tufts is/are fastened in the back material. The floor covering has means for increasing the drain of liquid from the nap when the floor covering is subjected to the influence of a force, such as a pressing force, a centrifugal force, and/or a pressure difference between the front and rear side of the floor covering. This means may be a normally closed perforation of the back material and/or an intermediate tissue via which the nap is secured to the back material. Preferably the intermediate tissue is a non-woven material, mainly consisting of synthetic fibres having a weight of 100-300, preferably 250 g per m.sup.2, a fibre thickness of 5-30, preferably 8 decitex, and a tissue thickness of 1-5, preferably 2 mm. Thereby a nap mat or carpet is achieved having a short drying time and/or provides a small drying energy consumption after washing.

Abstract: A machine and method to operate the machine to provide a plurality of valve-like perforations in the rubber-like backing of a nap mat or carpet by delivering the nap mat or carpet to and under a spiked roll. The machine includes a sensing device to ensure the leading and trailing edges of the nap mat are not perforated by the spiked roll.
