A coating apparatus includes: a container configured to accumulate a coating liquid; a rotatable coating bar arranged at an opening part so that the coating bar has a clearance between the coating bar and a downstream side end of an upstream side cover and a clearance between the coating bar and an upstream side end of a downstream side cover and a rotation axis direction of the coating bar is directed in a longitudinal direction of the container; a plurality of rotatable supports intermittently arranged along the rotation axis direction of the coating bar; and an in-liquid cover extending in the longitudinal direction of the container.

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.

Embodiments relate to a coating system. A substrate includes a first coating region and a second coating region adjacent to the first coating region. The coating system includes a first gravure mechanism and a second gravure mechanism, where the first gravure mechanism is configured to apply a first functional layer onto the first coating region, and the second gravure mechanism can receive the substrate having the first functional layer and apply a second functional layer made of a material different from that of the first functional layer onto the second coating region. In the coating system, with provision of first gravure mechanism and the second gravure mechanism, when the substrate is continuously transported in a same direction, the two functional layers made of different materials can be sequentially applied onto corresponding regions of the substrate.

A device for processing a strip guided along a running direction may include a roller holder disposed on a base frame so as to be pivotable about a pivot axis oriented substantially parallel to a strip running surface. A first processing roller may be disposed on the roller holder in the running direction and at a distance from the pivot axis perpendicular to the running direction and offset from the pivot axis such that by pivoting the roller holder, the first processing roller is moved toward the strip and the processing roller is moved away from the strip. A first counter-processing roller may be disposed transversely to the running direction at a further distance from the pivot axis than the first processing roller such that the first processing and counter-processing rollers interact to guide the strip if the first processing roller is moved toward the strip.

A coating device according to an aspect of the present invention includes a travel module that causes a strip-shaped sheet to travel in a longitudinal direction, a coating module that coats a surface of the strip-shaped sheet with ink while the strip-shaped sheet travels, and a supply module that supplies the ink to the coating module. The coating module includes a slot-type coating head that is disposed above the strip-shaped sheet so as to span the strip-shaped sheet in a width direction. The slot-type coating head includes an ink storage part that widens toward the strip-shaped sheet in cross-sectional view and an ink supply path that communicates with an upper part of the ink storage part.

A gravure kiss coater 1 includes a paint feeder 30 placed along a small-diameter gravure roll 10 having an outside diameter D in a range of 45-150 mm. The paint feeder 30 includes a doctor blade 32, a case 31, and a coating feed path 34, 35. A distal end 32a of the doctor blade 32 is directed in a direction opposite to a direction of rotation of the small-diameter gravure roll 10, and the small-diameter gravure roll 10 is capable of contacting the substrate S within a range of rotation angles equal to or less than 90 from the distal end 32a of the doctor blade 32.

A double-sided coater 1 includes a first coater 5a coating a surface not contacting a guide roll 4b, and a second coater 5b coating another surface contacting the guide roll 4b. Each of the first and second coaters 5a and 5b includes a gravure kiss coater including a small-diameter gravure roll 10 and a coating liquid supplier 30. The guide roll 4b guides a substrate S from a vertical direction to a horizontal direction to allow the first coater 5a to coat the substrate S from a lateral point while the substrate S travels vertically, and to allow the second coater 5b to coat the substrate S from a lower point while the substrate S travels horizontally.

Methods and apparatuses for masking the edges of a substrate when performing direct or reverse gravure coating using a kiss-coat configuration, particularly useful for in-line coating of biaxially oriented polymeric films. The methods and apparatuses include a masking plate configured to prevent the edge of a portion of a substrate from contacting a gravure roll, the masking plate includes a top portion having a Rockwell B hardness equal to or greater than 80, and a thickness of between 0.03125 inches and 0.375 inches. This masking plate prevents build-up of coating on the edges of the substrate which otherwise can cause film orientation production instabilities such as film breaks, sticking to tenter clips, and/or edge trim recycling incompatibilities. The masking plate provides a masking method that is effective and durable, minimizing production downtime and maintenance.
