The technical problems of the present invention reside in that coating liquor can be coated on a substrate web with certain even thickness when the mobile substrate web is coated with coating liquor intermittently from head of a coating model. Coating liquor (12) is coated on the mobile sheet substrate web (1) intermittently from a discharge opening (11) located at front end surface (10a) of the coating model head (10), while coating liquor is coated intermittently on the substrate web, the process as shown below: the coating model head and the substrate web are moved in same direction when the coating model head provides coating liquid to the substrate web; the coating model stopping moving or moving along the direction opposite to the substrate web, coating liquor being coated from the coating model head to the moving substrate web; When coating liquor is stopped providing to the substrate web from the coating model head, the coating model head and the substrate web are moving alongsame direction. |
