ARTICLES HAVING AN ACQUISITION LAYER WITH STRETCH OPENINGS AND PROCESSES TO MAKE THEM
First Claim
Patent Images
1. A process for continuously making absorbent articles on a converting line, the process comprising the steps of:
- providing a continuous stream of an acquisition material in a machine direction;
intermittently weakening the acquisition material in the machine direction to define openable areas;
stretching the acquisition material to open the openable areas thereby forming stretch openings in the acquisition material;
cutting the acquisition material to form discrete acquisition layers; and
attaching the discrete acquisition layers to other components of the absorbent articles to make absorbent articles, each acquisition layer comprising at least one of the stretch openings.

Abstract
An absorbent article such as a diaper comprising an acquisition layer with one or more longitudinally-extending stretch openings is provided. The stretch openings may be obtained by slitting and stretching an acquisition layer material. The topsheet forms recesses at the wearer-facing surface of the absorbent article as it folds inside the stretch openings. The stretch openings may provide a three dimensional profile on the wearer-facing side of the absorbent article in a simple and cost effective manner.

6. A process for continuously making absorbent articles on a converting line, the process comprising the steps of:
-
providing a continuous stream of an acquisition material in a machine direction; intermittently slitting the acquisition material in the machine direction to define openable areas; stretching the acquisition material in a cross-direction to open the openable areas thereby forming stretch openings in the acquisition material; cutting the acquisition material in a cross-direction to form discrete acquisition layers; and attaching the discrete acquisition layers to other components of the absorbent articles to make absorbent articles, wherein each acquisition layer comprises at least one stretch opening. - View Dependent Claims (7, 8, 9)

10. An absorbent article for personal hygiene comprising a wearer-facing side, a garment-facing side, and a longitudinal axis, the absorbent article having a length measured along the longitudinal axis, the absorbent article comprising:
-
a liquid permeable topsheet on the wearer-facing side; a liquid impermeable backsheet on the garment-facing side; an absorbent core between the topsheet and the backsheet; and an acquisition layer between the topsheet and the absorbent core; and wherein the acquisition layer comprises one or more stretch openings. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
