摘要： Before the start of coating, a deflector receives a curtain of a coating liquid free-falling from a coating hopper in order to prevent a continuously-running web from being coated with the coating liquid. At the start of the coating, the deflector is moved relatively to the coating hopper, so that the coating liquid can start to be applied to the web. A receding part is formed at the end of the deflector.

摘要： A curtain coating apparatus includes a hopper with a slide plane on which the coating solution flows and a hopper lip from where the coating solution begins to freely fall down as a free falling curtain. The apparatus also includes at least a pair of outlets disposed in a position along the edge part of the free falling curtain and situated at a fixed distance down from the hopper lip. Auxiliary solutions are introduced from the width directions so as to maintain the curtain in the width direction.

摘要： In a coating apparatus, a nozzle connects a feed pipe for feeding a coat solution to a manifold of a die with an opening of the manifold. The nozzle satisfies conditions: 1.5≦B/A≦5.0 and 0.8≦C/B≦8.0, when A is an equivalent diameter of an end of the nozzle to be connected with the tube, B is an equivalent diameter of another end of the nozzle to be connected with the opening, and C is a length of the nozzle. The coat solution fed from the feed pipe enters in the nozzle. In the nozzle, the coating solution diverges along with an inner wall of the nozzle to enter into the manifold. In the manifold the coating solution flows in a widthwise direction and flows out through a slit extending from the manifold to a lip of the die, such that a moving web is coated with the coating solution uniformly.

摘要： The coating apparatus has an air shielding device to prevent a curtain of coating liquids, which free-falls from a coating head, from being disturbed by an air carried along by a traveling web. The coating apparatus also has a device to move the air shielding device. Before and at the start of coating, the air shielding device is kept far from an impingement position where the free-falling curtain impinges onto the web. Just after the start of coating, the air shielding device is moved close to the impingement position. This prevents the air shielding device from being contaminated with splashes of the coating liquids, and the like.

摘要： In a simultaneous coating of multiple layers on a web using a slide hopper type coating apparatus, the gelatin concentration of the coating liquid for the bottom layer is set to be lower than the gelatin concentration of the coating liquid for the middle layer by at least 2 points in percentage, the ratio A/B, which is the flow amount ratio of the coating liquid for the bottom layer with respect to the entire multi-layered coating liquid, is set to be between 0.05 and 0.2, and the ratio C/D, which is the viscosity ratio between the coating liquid for the bottom layer and the coating liquid of the middle layer, is set to be between 0.2 and 0.67. Thereby, the flow of the multi-layered coating liquid flowing down on the slide surface can be stabilized.

摘要： A die of a coating apparatus for applying a coating solution includes down- and upstream blocks in a feeding direction of a web, which respectively have a first lip and a second lip. A lip land of the first lip is shorter than a lip land of the second lip in the feeding direction so as to satisfy a predetermined condition. In assembling the coating apparatus, bottoms of down- and upstream blocks are fixed to a fixer with bolts. Between the fixer and the downstream block, a plate member is provided such that the first lip land protrudes from the second lip land.

摘要： The mounting is formed by grinding an integrally molded material with accuracy of the μm order. An upper portion of the mounting is an L-shaped holding portion on which a slot die is positioned. An upper face of the holding portion contacts a lower face of the slot die, and a side face of the holding portion contacts a rear face of the slot die. The lower and rear faces of the slot die and the upper and side faces of the holding portion are formed to have such a straightness for the total length that the unevenness thereof may be in 5 μm. Thus the slot die can be held with high accuracy, and the clearance accuracy between the lips and a web can be increased.

摘要： The mounting is formed by grinding an integrally molded material with accuracy of the μm order. An upper portion of the mounting is an L-shaped holding portion on which a slot die is positioned. An upper face of the holding portion contacts a lower facer of the slot die, and a side face of the holding portion contacts a rear face of the slot die. The lower and rear races of the slot die and the upper and side faces of the holding portion are formed to have such a straightness for the total length that the unevenness thereof may be in 5 μm. Thus the slot die can be held with high accuracy, and the clearance accuracy between the lips and a web can be increased.
