Publication number: 20200331249Abstract: According to the lamination apparatus and the lamination method, a fast-curing adhesive can be used and which can improve die quality of a composite film and enables application of a low-viscosity coating liquid. The lamination apparatus 1 includes a first coating unit 12 that applies, as a coating liquid, one of a main agent and a curing agent of a two-component curable adhesive to a first web W1; a second coating unit 14 that applies, as a coating liquid, the other one of the mam agent and the coating agent of the two-component curable adhesive to a second web W2, the other one being the one not applied to the first web W1; and a bonding unit 151 that bonds a coating liquid-applied surface of the first web W1 and a coating liquid-applied surface of the second web together. The second coating unit 14 is a gravure coating machine.Type: ApplicationFiled: October 12, 2018Publication date: October 22, 2020Applicant: DIC CorporationInventors: Shigekazu Takahashi, Choichi Takada, Hidenobu Miura, Shinichi Matsunaga

Patent number: 9669421Abstract: 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.Type: GrantFiled: March 12, 2014Date of Patent: June 6, 2017Assignees: FUJI KIKAI KOGYO CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hidenobu Miura, Masakazu Umehara

Patent number: 9604246Abstract: 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.Type: GrantFiled: May 7, 2014Date of Patent: March 28, 2017Assignees: FUJI KIKAI KOGYO CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hidenobu Miura, Masakazu Umehara

Patent number: 9486828Abstract: First and second coaters, first and second edge determiners, and first and second moving mechanisms are provided. The first and second coaters apply a coating solution for forming a heat-resistant protection layer onto both surfaces of a substrate on each of which an active material layer is previously formed. The first and second edge determiners determine the locations of lateral edges of the active material layers formed on both surfaces of the substrate to be coated by the respective first and second coaters. The first and second moving mechanisms move the location of the substrate along the width thereof based on the locations of the lateral edges determined by the first and second edge determiners, respectively. The locations of regions of both surfaces of the substrate to be coated are separately adjusted.Type: GrantFiled: September 26, 2014Date of Patent: November 8, 2016Assignees: FUJI KIKAI KOGYO CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hidenobu Miura, Masakazu Umehara
