Abstract: A method and a device for applying large areas of glue used for a bottom film of an absorbent pad at the four corners of the bottom film of the absorbent pad of a health care article is described. The processes includes (a) gluing and conveying a release paper; (b) cutting the glued release paper; and (c) transferring the glue from the release paper to the absorbent pad.

Abstract: The invention provides a multilayer-structure absorbent core for a disposable absorbent article, and a method for preparing the absorbent core, wherein the absorbent core is compacted and formed by each layer; its surface presents a grid-shaped groove; the depth at the intersection point of the grid-shaped groove is bigger than that at the non-intersection point thereof. The invention adopts a new synchronous split-level process; that is, a linear grid-shaped trapezoid-shaped compaction mechanism, of which the height is smaller than that of a circular-platform structure, incompletely compacts the absorbent core and separates the absorbent core into numerous small convex spaces, while a circular-platform structure carries out the dot-shaped compaction for the absorbent core. Under the conditions that the liquid-absorption functions of a deflector layer and a reservoir layer are maintained, the movement of polymer water-absorption material is completely limited while the strength of a core body is enhanced.

Abstract: The invention discloses a method for applying large areas of glue used for a bottom film of an absorbent pad at the four corners of the bottom film of the absorbent pad of a health care article, comprising the following processes and steps: (a) gluing and conveying a release paper; (b) cutting the glued release paper; and (c) transferring an adhesive glue piece of the release paper. The invention also relates to a device for achieving the method for applying large areas of glue used for the bottom film of the absorbent pad at the four corners of the bottom film of the absorbent pad of the health care article. As to a glue piece applied on the bottom film of the absorbent pad of the invention, its peeling force may reach 20 N or more than 20 N; the width of the lump glue applied on the bottom film of the absorbent pad may reach 60 mm-450 mm; its length may reach 120 mm-1000 mm; and the normal production speed of the improved machine of the absorbent pad may reach 120-180 m/minute.
