According to one embodiment, a coating head includes a coating bar, nozzles, a first member, second members, third members, elastic members, and a position controller. The coating bar faces a coating member. The nozzles supply a liquid toward the coating bar. The first member includes first recesses. A portion of the nozzles is between the first recesses and the third members. The portion of the nozzles and the third members are fixed to the first member by the second members. The elastic members are located in at least first, second, or third positions. The first position is between the third members and the second members. The second position is between the portion of the first recesses and the nozzles. The third position is between the portion of the nozzles and the third members. The position controller controls a relative position between the coating bar and the nozzles.

A coated film having good characteristics is manufactured. A method for manufacturing the coated film includes: (a) a step of applying a coating liquid 20a to a first surface of a base material 1 unwound from an unwinding unit UW; (b) a step of forming a coating layer 3b on the first surface of the base material 1 by drying the coating liquid (coating film 3a) on the base material 1; and (c) a step of winding the base material 1 on which the coating layer 3b has been formed in a winding unit WD. Also, the base material 1 is continuously arranged from the unwinding unit UW to the winding unit WD, tension cut of the base material 1 is performed by a first suction roll SR after the base material 1 is taken out from the unwinding unit UW and before the step (b), and tension cut of the base material 1 on which the coating layer 3b has been formed is performed by a second suction roll SR before the step (c).

A coating device includes a roll that conveys a material to be coated or onto which a coating material is applied, and a coater used to apply a coating material onto the material to be coated or onto the roll. At least a portion of the roll to be in contact with a material to be coated or at least a portion of the roll onto which a coating material is applied is formed of a low expansion material that has a linear expansion coefficient in the range from 0 [1/K] to 6.0×10.sup.−6 [1/K] inclusive.

A web coating platform for depositing molten metal on flexible substrates is provided. The web coating platform can be used for manufacturing solid lithium anodes for use in energy storage devices, for example, rechargeable batteries. The coating platform can be designed for double-sided coating of a continuous flexible substrate (e.g., a copper foil) with molten lithium followed by double-sided lamination or passivation. The coating platform integrates novel coating elements unique to handling and processing molten metals. For example, some implementations of the present disclosure incorporate double-sided molten metal coating elements, which include at least one of a molten metal application assembly (e.g., kiss roller, slot-die, Meyer bar, and/or gravure roller), a primary melt pool assembly, a secondary melt pool assembly, and an engagement mechanism.

A coating device for moistening a flat substrate, particularly a paper web, comprising a liquid bath which is in contact with the liquid to be applied and a coating roller which is in contact with the liquid in order to take up a quantity thereof and transfer it to the substrate. The coating roller comprises a cylinder body having at a periphery thereof a cylinder surface which is covered with an absorption layer which is able and configured to take up liquid from the liquid bath and supply it to the substrate.

A lamination method, includes: a first coating step of applying any one of a main agent M and a curing agent H of a two-component curable adhesive as a coating liquid to a first web W1; a second coating step of applying the other one of the main agent M and the curing agent H as a coating liquid to a second web W2; and a bonding step of bonding a coating liquid-coated surface of the first web W1 and a coating liquid-coated surface of the second web W2, and of combining the main agent M and the curing agent H to increase a molecular weight. In addition, in the first coating step and the second coating step, the main agent M or the curing agent H is applied by a gravure coater.

Provided is an ultra large-width coating device applied to a consecutive process. More particularly, the present invention relates to a coating device capable of maximizing productivity by consecutively manufacturing a large-width film without reducing physical properties of the manufactured film by overcoming a problem in that a coating width is limited during a coating process using the existing contact type coating roller, and a method for manufacturing an ultra large-width membrane using the same.

An apparatus is disclosed for applying a strip of sealant to a web of roofing shingle stock as the web moves along a processing path. The apparatus includes an applicator wheel disposed on one side of the processing path and having a peripheral surface. The applicator wheel is rotatably mounted and oriented such that rotation of the applicator wheel moves the peripheral surface of the applicator wheel toward, adjacent to, and then away from the moving web of shingle stock. A nozzle preferably in the form of a slot die is disposed adjacent to the peripheral surface of the applicator wheel. A source of sealant is supplied and a delivery system is configured to deliver the sealant from the source of the sealant to the slot die under a predetermined pressure. The slot die and delivery system are configured to project a stream of sealant toward and onto the peripheral surface of the applicator wheel at a predetermined speed. This applies a coating of sealant to the peripheral surface of the applicator wheel. The moving web of roofing shingle stock engages the sealant on the peripheral surface of the applicator wheel as the peripheral surface moves adjacent to the web. This, in turn, draws sealant from the peripheral surface of the applicator and onto the web of roofing shingle stock thereby applying the strip of sealant to the web.

Example implementations relate to selectively deflecting substrates. One example implementation includes an apparatus to selectively lift a part of a substrate away from a transfer member when the substrate is advancing in a substrate coating system relative to the transfer member, such that, across a width of the substrate, a first part of the substrate is coated by the transfer member and a second part of the substrate, that is lifted by the apparatus, remains uncoated.

Paper is disclosed for use in making repositionable or removable adhesive labels. The adhesive can be applied in patches or discrete areas to the paper or to a layer of material that cleans rollers in the manufacturing line and/or in printers. The adhesive can be applied in single or multiple layers. The paper is light weight paper and preferably thermal paper for use in POS printers.
