Provided are a coating device and a coating method which suppress the occurrence of exhaustion of a coating liquid. A coating device which applies a coating liquid to an upper surface or a lateral surface of a long substrate continuously traveling in a specific traveling direction has: a bar which is capable of being brought into contact with the upper surface or the lateral surface of the long substrate continuously traveling in the specific traveling direction via the coating liquid, and is rotated; and at least two stages of dam plates which are provided on the upstream side in the traveling direction of the long substrate with respect to the bar, and allow the coating liquid to flow to the long substrate via a space between the dam plate and the bar. The at least two stages of dam plates are arranged along the traveling direction.

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer operatively connected to the stitches to provide dimensional stability for the entire floor covering. The reinforcement layer is made of fibers and adhesive that are formed into a reinforcement layer of laminated fibers that is operatively connected to the stitches and/or the fibers and adhesive are formed into a layer of fibers and adhesive that is contained within the stitches. The fibers and adhesive are mixed and then moved by an applicator toward the stitches. A curved slip path is formed on a curved portion of the applicator to improve the movement of the fibers and adhesive toward the stitches. A removable tip portion on the end of the curved portion of the applicator improves the penetration of the adhesive and provides compression of the fibers towards the ends of the stitches. A releasable adhesive cover system is provided to cover the layer of fibers for providing additional strength and stability and for providing a releasable attachment of the universal floor covering to a supporting surface.

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer operatively connected to the stitches to provide dimensional stability for the entire floor covering. The reinforcement layer is made of fibers that are initially contained within a composition of adhesive and fibers. Mixing of the adhesive/fibers composition and/or injection of compressed air, assists in preparing the adhesive and fiber composition to be in the preferred condition and position prior to the forming of the reinforcement layer. Multiple sources of pressure, including vacuum, are applied in a controlled manner for moving the adhesive and fiber composition to form a reinforcement layer of fibers that is operatively connected to the stitches and/or to form a layer of fibers and adhesive that is contained within the stitches. The universal floor covering is selectively cut and transported in a roll for installation, and it can be conveniently recycled if necessary.

A slurry feed apparatus for depositing a slurry upon a moving forming web having a direction of travel, including: a headbox mounted transverse to the direction of travel of the moving web, having a back wall, sidewalls, a concave transverse front wall, an open top, and an open bottom for directing slurry onto the forming web; a moveable dam releasably attached to the back wall, a seal attached to a bottom wall of the dam; and a headbox support system extending from opposed the sidewalls. Also disclosed is a continuous process for depositing a uniform layer of a cementitious slurry containing reinforcing fibers from the headbox onto a traveling web.
摘要:
A method for transferring objects onto a substrate, or running substrate, the objects to be transferred being placed in a transfer area containing a carrier liquid forming a conveyor, the objects being held by a compact film of particles floating on the carrier liquid of the transfer area, within which the objects are displaced with the film of particles to be transferred onto the substrate, making at least one connector on at least one of the objects, the connector being made by a substance comprising a polymerizable compound, put in contact with the object arranged within the transfer area, and then by polymerization of the substance.

A dimensionally stable universal floor covering includes a tufted textile substrate and a reinforcement layer to provide dimensional stability for the entire floor covering. Vacuum, mixing, and injection of compressed air assists in preparing an adhesive and fiber composition to be in the preferred condition and position before the application of pressure to form the reinforcement layer. The universal floor covering is selectively cut and transported in a roll for installation, and it can be conveniently recycled if necessary.
摘要:
A dimensionally stable floor covering, comprising a tufted textile substrate and a reinforcement layer wherein vacuum is used to move adhesive into stitch portions of the yarns and into the back side of the primary backing substrate to provide increased dimensional stability for the entire floor covering. Mixing of reinforcement fibers and adhesive takes place before in situ filtration of the adhesive and fibers. Further, compressed air is injected into the adhesive/fiber composition to provide spaces between the fibers before application of pressure to the composition. The vacuum, mixing, and injection of compressed air assist in preparing the adhesive and fiber composition to be in the preferred condition and position before the application of pressure to the composition.

There is provided an applicator that applies a coating liquid onto the upper surface of a web, and an application method which are capable of sufficiently enhancing the evenness of a coating surface. The applicator includes: a bar which rotates while coming into contact with the upper surface of the continuously travelling web via the coating liquid; and a barrier plate which is provided on an upstream side of the bar in a travelling direction of the web and allows the coating liquid to flow in a direction toward the web between the barrier plate and the bar, in which, when a distance between the barrier plate and an end edge portion of the bar, which is closest to the barrier plate, is referred to as A and a distance between the barrier plate and the web is referred to as B, A is 0.5 mm to 5 mm, B is 0.5 mm to 5 mm, and is satisfied.
摘要:
The invention relates to a method for coating a catalyst support body, which comprises: providing the catalyst support body as well as slurry located within a pan; introducing an open input end of the catalyst support body into the slurry; and, subsequently, directing an amount of the slurry though the input end and into the inside of the catalyst support body. At least a part of the circumference of the input end is covered with an impermeable sealing element while slurry is directed through the open end. In this way, contact between slurry and a circumferential outer surface of the catalyst support body is prevented and slurry is provided through the open end to an inner surface of the catalyst support body. Further, the invention relates to a loading platform for carrying out the method. The inventive assembly comprises a loading platform adapted for releasably holding a catalyst support body, and a cover mechanism having a sealing holder and a ring shaped sealing element attached to the sealing holder. The cover mechanism further comprises a first lifting mechanism connected to the sealing holder, wherein the first lifting mechanism provides a moving direction for the sealing holder along a longitudinal axis of the sealing element relative to the loading platform. In addition, the invention relates to a coating station comprising the loading platform. The coating station comprises a slurry pan and a second lifting mechanism providing a relative moving direction between the pan and the loading platform. The first lifting mechanism is synchronized with the second lifting mechanism by a synchronization device.
