りがちである。However, the conventional coating roll has the following problems. (1) While the coating material is applied to the front or back surface of the base material A by the rotating coating roll C, the coating material is moved in the lateral direction of the base material A along the spiral groove B and gradually becomes the same roll. C
Of the coating agent, the coating thickness of the coating agent becomes non-uniform. Further, when a large amount of the coating agent is supplied to the coating roll C, the coating agent which is moved in the lateral direction of the base material A may overflow from the side of the base material A, and the periphery of the base material A becomes dirty. (2) If air bubbles are entrapped in the spiral groove B during the application operation, the application of the coating agent is not applied to the foam portions, so that the coating remains. Furthermore, since the foam moves along the spiral groove B, the unpainted portion of the foam also moves along the spiral groove B, and the unpainted portion of the foam may be scattered on the application surface of the base material A. (3) The air bubbles entrapped in the spiral groove B during the coating operation often burst and pinholes are generated on the coating surface of the substrate A. (4) The spiral groove B is a single groove, and the coating roll C
Since the surface of the spiral groove B has the same depth, if a part of the spiral groove B is clogged, it becomes difficult for the coating agent to flow after the clogged portion, and the coating thickness of the coating agent may become uneven. (5) Generally, when only one spiral groove is formed on the application roll C, cleaning and maintenance are troublesome. (6) In general, in the conventional application roll, the application thickness of the application agent tends to be thicker at both end portions of the substrate A than at other portions.
