摘要： PURPOSE:To control the catenary within a narrow shape range and to produce coated band steels of various sizes by providing a tension command unit for changing the tension of a band steel so that the catenary is controlled within a specified shape range based on the indication of a shape detecting sensor. CONSTITUTION:The shape detecting sensor 13-1 is not actuated when the catenary is below 4-3. When the catenary reaches 4-3, the fact is detected by the sensor. The shape detecting sensor 13-2 is not actuated when the catenary is above 4-4. When the catenary reaches 4-4, the fact is detected by the sensor. Accordingly, whether the catenary is between 4-3 and 4-4 or not is detected by using the sensors 13-1 and 13-2. The fact that the catenary reaches 4-3 is indicated to a tension command unit 14 by the sensor 13-1, and a command is given to a tension control unit 7 by the unit 4 to reduce the tension of the band steel.

摘要： PURPOSE:To make peeling of coating easy even when coating difficult to be peeled from a coating roll is utilized by providing an elevation mechanism and a back and forth progressing mechanism to a blade. CONSTITUTION:An elevation mechanism 16 is slid back and forth by the air cylinder of a back and forth progressing mechanism 17 on a sliding base 18 and thereby a blade is progressed back and forth. Furthermore after the elevation mechanism 16 is moved to the prescribed position on the sliding base 18, the blade 3 is elevated by utilizing the air cylinder of the elevation mechanism 16. As a result, the blade 3 is allowed to abut against a coating roll 1 even at the position near to a coating reservoir and at the position far therefrom in the lower part of the coating roll 1. Coating is peeled from the coating roll 1.

摘要： PURPOSE:To form a film having uniform thickness by providing a roll gap to the upper part of the material to be coated and oppositely arranging a coating roll and a doctor roll and constituting both the coating roll and the doctor roll of a crown-fitted roll. CONSTITUTION:A coating roll 1 and a doctor roll 2 which are fitted with a crown are arranged so that the prescribed roll gap 10 is always maintained. As amount C of the crown, the amount for canceling the flexure amount due to the gravity of the coating roll 1 and the doctor roll 2 is imparted to either roll or imparted to both rolls while sharing this amount with each other. Thereby fluctuation of film thickness is dissolved and the film having uniform thickness is obtained.

摘要： PURPOSE:To prevent fluctuations in a film thickness by forming a coating roll and a doctor roll as hard rolls and sliding a blade on the coating roll in the body length direction thereof. CONSTITUTION:Paint P is supplied to the roll gap between a hard coating roll 7 and a hard doctor roll 8 from a paint supply pipe and subsequently allowed to flow along the hard coating roll 7 downwardly and scraped off by the blade B brought into contact with the coating roll 7. The scraped-off paint flows along the stage N of the guide plate 12 provided to a blade stand 9 and separates from the leading end W thereof to form a paint curtain C which is, in turn, applied to the plate 1 to be painted passing under the blade B. Pressure bonding adjustment is performed by bringing the blade B to a state capable of being closely brought into contact with the coating roll 7 by preliminarily regulating the screws 10, 11 of the blade stand 9. By this method, yield is enhanced.

摘要： PURPOSE:To easily adjust a film thickness, by detecting the contact surface pressure of the contact roll in contact with a painting rubber roll on the side opposite to a doctor roll and displacing the doctor roll on the basis of the detected value to adjust a roll gap. CONSTITUTION:A doctor roll 3 and a contact roll 13 are respectively n contact with a painting rubber roll 2 lightly to set a zero point. Subsequently, the contact roll 13 is fixed at that position and a drive apparatus 5 is driven to separate the doctor roll 3 from the painting rubber roll 2 to set a predetermined roll gap. When the painting rubber roll 2 expands with the elapse of painting work and the roll gap becomes small, the contact surface pressure acting between the painting rubber roll 2 and the contact roll 13 becomes high and this pressure is detected by a load cell 19. A computer 21 operates the correction value of the roll gap on the basis of the detected contact surface pressure and the bearing stand 4 of the doctor roll 3 is retracted by the driven apparatus 5.
