Since the adhesive tape whose side surface is cut so that the angle between the side surface of the adhesive tape parallel to the width direction and the side surface of the adhesive tape is in the range of 45 ° to 75 ° is used, the belt-shaped flexible support is used as a transport roller or the like. The adhesive can be prevented from protruding from the end of the adhesive tape when passing through the contact means of the transfer means. As a result, it is possible to prevent the adhesive of the adhesive tape from adhering to the conveying roller and transferring the adhered adhesive to the downstream web, so that the adhesive is applied to the belt-shaped flexible support having the adhesive tape at the joint. It is possible to prevent application unevenness and application streaks from occurring when the liquid is applied. Also, there is no occurrence of coating unevenness due to entrainment of air at the joint.

が減圧される。As shown in FIG. 1, a plurality (for example, three types) of coating solutions 16A, 16B, 16
C is supplied to each of the manifolds 18A, 18B, and 18C in the slide hopper 12 from each of the coating liquid tanks (not shown) by each of the liquid supply pumps whose liquid supply amount is variable. Each of the coating liquids 16A, 16B, and 16C supplied to the manifolds 18A, 18B, and 18C is expanded in a coating width direction so as to have a predetermined width, and then each of the slit-shaped slots 20A, 20B, and 20C is formed. It is pushed out to the slide surface 22 inclined downward on the upper surface of the slide hopper 12. Each coating solution 16 extruded on the slide surface 22
A, 16B and 16C are multilayer coating films 16 in the form of a multilayer coating film.
As a result, it flows down the slide surface 22 and reaches the lip tip 24 at the lower end of the slide surface 22. On the other hand, the web 14 having the joining portion 28 joined by the rectangular adhesive tape 26 is
A backup roller 32 disposed opposite to the slide hopper 12 via a transport roller 30 provided in the transport path.
And is conveyed while being engaged. And the lip tip 24
Reaches the gap between the lip tip 24 and the surface of the web 14 supported and engaged by the backup roller 32, in which a web 14 is formed around the backup roller 32. It is conveyed upward from below along the surface. Thus, the multilayer coating solution in the bead portion 34 is stretched by the action of being pulled up on the surface of the web 14 to be thinned. As a result, a thin multilayer coating film 16 can be formed on the surface of the web 14 to be conveyed. At this time, in order to stabilize the bead portion 34, the pressure on the lower side of the bead portion 34 is reduced by the suction chamber 36.

布品質に与える影響が大きい。In the application of the coating solution to the web 14, as shown in FIG. 1, when the joining portion 28 of the web 14 passes while being wrapped around the transport roller 30, the adhesive layer 38 of the adhesive tape 26 is used. (See FIG. 3 and FIG. 4). The adhesive 38 </ b> A protruding from the end of the adhesive tape 26 adheres to the transport roller 30 while being pressed between the transport roller 30 and the web 14.
When the adhered adhesive 38A is transferred to the downstream web 14, spot-like coating unevenness occurs on the multilayer coating film 16 applied to the web to which the adhesive has been transferred as shown in FIG. In this case, the glue 38A protruding from the side surface in the web width direction of the adhesive tape 26 for joining the joining portion 28 is applied to the web 1
4 is transferred to the ears (both ends of the web), so the influence is small. However, the glue sticking out from the side surface of the adhesive tape 26 parallel to the web width direction is transferred to the center of the web 14, so the influence on the coating quality is affected. Is big.

Is transferred to the central portion of the web 14 and therefore greatly affects the coating quality. Therefore, the side surface 4 is set so that the side angle α parallel to the width direction of the web 14 is in the range of 45 ° to 75 °.
It is preferable to use an adhesive tape 26 obtained by cutting 6.
The side angle α of the two opposing side surfaces 46 is
6 may have the same side angle α, or different side angles α. Also, the effect can be obtained by setting the side surface angle α of only one side surface 46 in the range of 45 ° to 75 °.

Therefore, it is necessary to prevent the adhesive from running out from the end of the adhesive tape 26. Can be. As a result, the pasted adhesive 38A adheres to the transport roller 30 as in the related art,
Since the adhered glue is not transferred to the downstream web 14 to cause uneven coating, the coating quality can be improved.

間６２をなくす方向に作用するためと考察される。The side angle α of the adhesive tape 26 is 45 ° to 7
The reason why the glue is prevented from running out by satisfying the range of 5 ° is as shown in FIG.
Since the side surface 46 of the sixth taper 6 is appropriately inclined, the web 14 can easily adhere to not only the adhesive layer 38 but also the side surface 46 of the adhesive tape 26. As a result, the side surface 4 of the adhesive tape 26
Since the gap 62 is not formed between the web 6 and the web 14, it is considered that the adhesive is prevented from running out from the end of the adhesive tape 26. In particular, when the web 14 wraps around the transport roller 30, the web 14 more easily adheres to the side surface 46 of the adhesive tape 26. Therefore, even if the adhesive layer 38 is Is considered to act in a direction to eliminate the gap 62 between the side surface 46 of the adhesive tape 26 and the web 14.

8, the side angle of the adhesive tape 26 parallel to the width direction of the web 14 is 45 ° to 75 °.
Is used, so that the adhesive can be prevented from protruding from the end of the adhesive tape 26 even when the web 14 passes through the transport roller 30. As a result, it is possible to prevent the adhesive of the adhesive tape 26 from adhering to the transport roller 30 and the like, and preventing the adhered adhesive from being transferred to the downstream web 14.
When the application liquid is applied to the web 14 having the adhesive tape 26 on the joint portion 28, application unevenness and application streaks can be prevented from occurring, and application quality can be improved.
