摘要： PROBLEM TO BE SOLVED: To provide a peripheral surface immersion type gravure coater for positively discharging air bubbles contained in a coating solution within a chamber to eliminate the filling of a cell with the air bubble-containing coating solution and preventing the leak of the coating solution from the contact part of a doctor with a gravure roll to always perform proper coating. SOLUTION: This peripheral surface immersion type gravure coater is equipped with the gravure roll 2, a coating block 3, a coating solution supply device 5 for forcibly supplying the coating solution into the chamber 4 and a coating solution recovery device 6 for recovering the excess coating solution in the chamber 4. The coating solution is supplied to the end part on the side of the doctor 8 in the chamber 4 in a state containing an air layer part 23, and coating is performed in such a state that negative pressure air is allowed to act on the air layer part 23 by a negative pressure device 27. Air bubbles contained in the coating solution are floated to the air layer part 23 to be diffused and discharged through an exhaust passage 25 to effectively remove air bubbles in the coating solution. Since the supply pressure of the coating solution does not act on the doctor 8, the leak of the coating solution can be certainly eliminated. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To eliminate the occurrence of a winding failure caused by the repetition of contact and separation of a roll coming in pressure contact with a rewinding roll or plastic deformation caused by striking the peripheral surface of the roll in a rewinding device for rewinding a web again into roll shape after cutting both ends of the web delivered from a web roll. CONSTITUTION:A web rewinding device has a rewinding roll 8 rotatory-driven by a rewinding shaft 9. An elastic roller 5 is brought into pressure contact with the rewinding roll 8 to wind a web W. The elastic roller 5 has a rubber elastic layer 17 on the peripheral surface of a roller core 16, and the outer peripheral surface is covered with a roller cylinder 18 made of metal. The displacement on the verge of being caused to the elastic roller 5 by the fluctuation of contact pressure between the elastic roller 5 and the rewinding roll 8 is absorbed by the resilience of the elastic layer 17, so that the elastic roller 5 can be always kept in external contact with the rewinding roll 8.

摘要： PURPOSE:To obviate the necessity of replacing a backup roll or the like even when the web width is varied by making the contact pressure of a web to an applicator roll small and coating uniformly in a manner of forming no cross lines on a film on the web. CONSTITUTION:An applicator roll 8 is provided in a roll coater. A first guide roll 9 is disposed in the web feed direction on the upstream side of the applicator roll 8. A second guide roll 10 is disposed in proximity in the web feed direction on the downstream side of the applicator roll 8. A gravure roll with recesses on the outer peripheral face is used as the applicator roll 8, and rotated reversely in the web feed direction. The second guide roll 10 is a suction roll for suction retaining a web W to which a vacuum pressure is applied, and rotated in the same direction as the web feed direction. The web W is driven and guided in a manner of being brought into contact with the outer peripheral face of the applicator roll 8 by the first and second guide rollers 9 and 10.

摘要： PURPOSE:To indirectly detect the present coating state of a roll coater by calculating the coating amount/a unit area on a web from the detected running speed of the web and the consumption speed of a coating agent. CONSTITUTION:A pan 6 is filled with a coating agent 5 by a supply pump 10 and the liquid level C of the coating agent is set to a predetermined level D with respect to a gravure roll 2. Next, when a switch of detection-ON is closed, the supply of the coating agent is stopped and, at the same time, the initial wt. M1 of the coating agent 5 containing the pan 6 is calculated by a load cell 12 to be stored in a display part 16 and, continuously, the wt. M2 of said coating agent 5 after the elapse of T-sec is measured. The running speed S1 of a web 4 can be calculated on the way of the feed of the web 4 or from the rotational speed of a gravure roll 2 or that of a backup roll 3. As a result, when the width 4 of the web 4 is set to W, the coating amount M of the coating agent applied per the unit area of the web 4 can be calculated by formula (1).
