It is configured to be adjusted.

Meanwhile, a back roll is formed on the rear upper surface of the pair of side frames on which the fabric supplied in a wrinkled state is wound and transferred from an unwinder (not shown) through a FLEXPANDER ROLL.

Although the conventional coating device with this configuration needs to adjust the gap between the back roll and the slot die more conveniently, more quickly, and more precisely using a gap adjustment device in order to uniformly apply the coating liquid to the film fabric. In addition, a slot die is directly fixed to the upper surface of the single-plate transfer plate, and a gap adjustment device is installed in conjunction with both left and right sides of the transfer plate, so that when adjusting the gap adjustment device, the transfer plate is Since it moves all at once, it is difficult to adjust the left and right deviation, it takes a lot of time, and there is a problem in that precise control is difficult.

Therefore, according to patent registration number 10-1056093 in the patent document, in order to solve the above problems, the slot die is not directly installed on the upper surface of the transfer plate that can be transferred forward and backward toward the back roll by a pneumatic actuator, but is installed on both sides of the upper surface of the transfer plate. By installing a fine gap adjusting device of a special structure on each and indirectly fixing the slot die to the upper surface, the fine gap adjusting devices installed separately on both sides of the upper surface of the transfer plate are separately adjusted, thereby adjusting the fine gap on the left and right sides of the slot die. It was possible to adjust the angle.

However, the fine gap adjustment device, which is made only by moving the throat die forward and backward, had many shortcomings in uniform application of the coating liquid to the back roll.
