Abstract: A gluing mechanism incorporating a notched glue scraper and a method thereof are disclosed. A glue dispensing roller is provided adjacent to a web material traveling path where a web material is conveyed to get past, and operated to touch glue contained in a glue tank, and accordingly, a glue carrying roller surface of the glue dispensing roller is coated with the glue. A notched scraper blade, which faces the glue carrying roller surface of the glue dispensing roller, scrapes the glue stayed on the portion of the glue carrying roller surface, which corresponds with the non-notched area of the scraper edge. Comparatively, the glue stayed on the rest of the glue carrying roller surface is formed a glue layer for subsequently applying to a gluing side of the web material, wherein the rest of the glue carrying roller surface corresponds with notched area of the scraper edge.
