Patent ID: 8424481

Claim:
A gluing mechanism adapted to apply glue to a gluing side of a web material traveling along a web material traveling path, the gluing mechanism comprising: a glue dispensing roller disposed adjacent to the web material traveling path and faces the gluing side of the web material, wherein the glue dispensing roller is driven to rotate according to a predetermined rotation direction, and the glue dispensing roller defines a glue carrying roller surface; a glue tank provided beside the glue dispensing roller and containing an amount of glue; a notched scraper blade facing the glue carrying roller surface of the glue dispensing roller, wherein the notched scraper blade comprises a scraper edge for touching the glue carrying roller surface of the glue dispensing roller, and the scraper edge of the notched scraper blade comprises at least one notch; a glue collection tank provided below the glue dispensing roller by a given distance; at least one pushing member facing a contact side of the web material, wherein when the pushing member is driven to rotate to a pushing position, the web material is pushed by the pushing member to touch a glue layer on the glue carrying roller surface of the glue dispensing roller and the gluing side of the web material is coated with the glue; and a fender provided above the glue dispensing roller and used to lightly touch the gluing side of the web material; wherein when the glue dispensing roller rotates, the glue carrying roller surface of the glue dispensing roller contacts and carries the glue from the glue tank; wherein when the glue is carried by the glue carrying roller surface of the glue dispensing roller, and passes through the at least one notch of the scraper edge of the notched scraper blade, the scraper edge of the notched scraper blade scrapes the glue from a portion of the glue carrying roller surface corresponding with a non-notched section of the scraper edge; wherein the glue layer is formed on the glue carrying roller surface of the glue dispensing roller by the glue passing through the at least one notch of the notched scraper blade; wherein a gap is provided between the web material and the glue layer; and wherein after the web material is pushed by the pushing member to be coated with the glue, the web material is separated from the glue layer on the glue carrying roller surface of the glue dispensing roller.
