No. 50-2451 and the like. For the crossover of the tubular air chamber in the spiral winding method, see Japanese Patent Publication No. 48-44151.
According to the publication, a long flexible support (web) which has an air supply port and an air outlet port and which has a surface to be dried inwardly wound and travels in a spiral path is provided with an air film. Two or more cylindrical air chambers arranged substantially parallel to each other that are supported and dried from the inside, and are arranged between the cylindrical air chambers, and receive the support from one of the cylindrical air chambers to the other. In order to deliver, the traveling of the support that is separated from the spiral-shaped path of one cylindrical air chamber and the traveling direction of the support that enters the spiral-shaped path of the other cylindrical air chamber are substantially parallel to each other, and A diversion roll is disclosed that forms the support path in the opposite direction.

That is, this method is a non-contact conveyance by a spiral winding method, but by supporting the opposite side of the drying surface of the support body with a very small number of rolls, the flapping of the bridging portion between the cylindrical air chambers, etc. This is to eliminate the instability of. FIG. 3 is a drawing described in the patent specification, and in FIG. 3A, the web 1 which has been conveyed in the cylindrical air chamber A in a non-contact manner is changed into another cylindrical air by the direction changing roll 3.

In this case, the greatest advantage of the tumble drying method is non-contact conveyance, but in the first place, the transfer portion of the support between the cylindrical air chamber or between the cylindrical air chamber and other rolls is from the support passage. It becomes a jet outlet of gas, which is a place where the support height of the support changes abruptly, so that the gas flow near the outlet tends to be turbulent,
As a result, the holding force of the support becomes unstable, which causes flapping. Moreover, when the meandering occurs, a partial decrease in the floating amount is likely to occur, which causes a surface rubbing failure.

A detailed view of the tilting device is shown in FIG. 1 (b). In the figure, 1 is a web, 3 is a gas blow-out box of the web transfer part, and 6 is a fulcrum when tilting. This fulcrum is provided at the center of the blowing box and tilted by the hydraulic cylinder 4. Hydraulic cylinders can be provided on both sides or one side of the blow-out box, or can be motor driven instead of hydraulic. Such meandering between the tubular air chambers or the transfer portion thereof is performed by using a gas blowing box as shown in FIG.
This can be suppressed by making it possible to tilt in the width direction of the support by the mechanism as shown in (b). Further, when the meandering is large, two or more gas outlet boxes are arranged as shown in FIG. 2 and one or more of them can be tilted, so that the effect of suppressing the meandering becomes large. In particular, when three or more gas outlet boxes are installed at the transfer section of the tubular air space, it is effective to fix the gas outlet box closest to the tubular air chamber and tilt the remaining one or more. Further, the partial decrease in the floating amount caused by flapping of the support or meandering is increased by tilting two or more of them at the same time in the same direction. In this case, the gas blowing box in the vicinity of the cylindrical air chamber may be tiltable. In the non-contact transfer method, the support force in the width direction of the support is very small, so when the meandering is large, the tilting amount of the air blow-out box in the transfer part also becomes large, and the front air chamber and the rear side with respect to the transfer part. The support of the air chamber is affected. The front air chamber corresponds to A in FIG. 3- (a), and the rear air chamber is B in the same figure.
That is. However, in this case, it is possible to change the traveling position of the support without changing the tension distribution in the width of the support, and it is possible to reduce the influence on the front air chamber and the rear air chamber of the transfer line. Therefore, stable transportation becomes possible. In addition, as shown in FIG.
The effect is further enhanced by providing the side guide as shown in (d). In particular, when trying to suppress meandering only with the side guides, the meandering force of the support is strong.For example, a support coated with a silver halide photographic light sensitive material has a very low rigidity and a scratch failure or damage is caused only by contacting the side guides. In the worst case, the support may be broken. On the other hand, by using the above method and the side guide together, large meandering can be dealt with by tilting the gas blowing box, and relatively small meandering can be suppressed by the side guide.

Further, in non-contact conveyance, the vibration of the support may become a problem. For example, in the case of coating and drying a silver halide photographic light-sensitive material, the vibration of the support causes coating unevenness, drying unevenness, or even surface rubbing failure during transportation. When the vibration of the support of the support of the tubular air chamber is large, it can be suppressed to some extent by shortening the distance between the air chamber of the tubular air chamber and the air blowing box of the delivery, but it is shown in FIG. As described above, in order to increase the space efficiency, when describing the cylindrical air chambers in parallel, the supporter travel path must enter at a certain angle to the cylindrical air chambers, and the distance is defined as the supporter width. It is impossible to reduce the length of the air blow-out box and the cylindrical air chamber by hand at the same distance. The perspective view is shown in FIG. Reference numeral 1 is a support, A is a cylindrical air chamber, and 3 is a gas blowing box. The separation line between the cylindrical air chamber of A and the support is on ab, and the entry line to the gas blowing box is a cd line. In this case, b- rather than a-c
The distance d is shorter. In other words, if one of the distances is wider than the other in the width, and if flapping of the support occurs, the longer and shorter vibration frequencies of the crossover are different, Becomes very unstable and the vibration becomes large. FIG. 5 is an example in which the blow-out box (3 in FIG. 4) of the air in the delivery section is changed to a damping roll, and FIGS. 5 (b), (c), and (d) show various damping rolls. It is a perspective view shown, and Drawing 5 (a) is a perspective view of a web transfer part using a damping roll. As shown in the perspective view of FIG. 5A, it is possible to reduce the fluttering of the transitional portion by disposing the vibration control roll in the vicinity of the cylindrical air chamber.
Further, it becomes possible for this vibration control roll to also have a meandering prevention function which allows the air blow-out box shown above to be tilted.
When the vibration control roll can be tilted in the width direction of the support, the most preferable embodiment is to wrap the vibration control roll 180 degrees with the support. When this method is also used, the vibration is remarkably reduced as compared with the conventional method, and the high-speed conveyance stability is improved.
As an example of this vibration control roll, the method described in JP-A 1-209257 can be used.

According to this method, the support is held by one or more gas ejection cylinders and conveyed. In particular, when the distance between the support members at the transitional portion of the tubular air chamber is long and when the internal pressure of the tubular air chamber is high, as shown in the perspective view of FIG. By making it possible, it becomes possible to reduce vibration. Further, in order to obtain a high effect with a small number, it is possible to take a large wrapping angle of the support 1 on the vibration control roll 7 as shown in the perspective view of FIG. 5C. Further, as shown in the roll perspective view of FIG. 5D, the vibration control roll 7 and the gas blowing box 3 may be used in combination.
