Abstract

A method including folding incontinence pads which have a substantially rectangular shape, elongate according to a longitudinal axis, and including a central absorbent pad and a perimetric edge. The method includes folding parts of the edge onto a central portion of the absorbent pad, folding a first end portion of the incontinence pad about a first fold line onto the central portion and a subsequent step of folding, about a second fold line a second end portion onto the first portion. The fold lines which are transversal to the longitudinal axis and define the central portion are spaced by a stretch which is greater than or equal to the longitudinal dimension of the first end portion. The folding step is preceded by a step of folding down inwards onto the central portion segments of the edge which lie between the first and second fold lines, and a step of retaining said segments of the edge on the central portion.

First claim

The invention claimed is:

1. A method for folding incontinence pads having a substantially rectangular shape, elongate and having a first end portion, central portion, and second end portion according to a longitudinal axis, and comprising a central absorbent pad, a back sheet, a top sheet, and a perimetric edge comprising perimetric edges of the back sheet and the top sheet, the method comprising, in the following order, steps of:
folding elasticized segments of the perimetric edge located on sides of the incontinence pads opposed across the longitudinal axis down inwards onto the top sheet in the central portion;
retaining the elasticized folded segments on the top sheet in the central portion; and
folding each incontinence pad at a first and a second fold line both transversal to the longitudinal axis, the folding step comprising a first sub-step of folding the first end portion of the incontinence pad about the first fold line onto the top sheet in the central portion of the incontinence pad, and a second sub-step of folding the second end portion of the incontinence pad about the second fold line onto the first end portion,
wherein the distance between the first and second fold lines measured along the longitudinal axis of the incontinence pad is greater than or equal to the longitudinal dimension of the first end portion, and
wherein the elasticized folded segments are located between the first and second fold lines, and,
wherein, before being folded, the elasticized segments extend away from the central absorbent pad in the transverse direction no further than an extent in the transverse direction of non-elasticized segments of the perimetric edge along the same side of the central absorbent pad.

2. The method according to claim 1 , wherein the retaining step continues at least until the end of the first folding sub-step.

3. The method according to claim 1 , wherein the distance between the first and second fold lines is equal at least to one third of the longitudinal dimension of the entire incontinence pad.

4. The method according to claim 3 , wherein the distance between the first and second fold lines is between 60 and 150 mm.

5. The method according to claim 1 , wherein, once folded down inwards onto the top sheet in the central portion, the elasticized folded segments are separated from each another in a direction at a right angle to the longitudinal axis of the incontinence pad by a distance of between 35 and 70 mm.

6. The method according to claim 1 , wherein the first end portion of the incontinence pad constitutes, in use, the front portion of the incontinence pad.

7. The method according to claim 1 , wherein the first end portion of the incontinence pad constitutes, in use, the rear portion of the incontinence pad.

8. The method according to claim 1 , wherein the second folding sub-step is followed by a step of folding the non-elasticized segments of the perimetric edge between the first fold line and a first end of the incontinence pad and the non-elasticized segments of the perimetric edge between the second fold line and a second end of the incontinence pad around the first end portion and towards sides of the central portion of the central absorbent pad.

9. The method according to claim 1 , wherein the second folding sub-step is followed by a step of folding the non-elasticized segments of the perimetric edge between the first fold line and a first end of the incontinence pad and the non-elasticized segments of the perimetric edge between the second fold line and a second end of the incontinence pad around the first end portion until they are superposed on sides of the central portion of the central absorbent pad.

10. The method of claim 1 , wherein the elasticized segments are adapted to cause the first end portion to adopt a predetermined angle relative to the central portion.

11. A method for folding incontinence pads having a substantially rectangular shape, elongate and having a first end portion, central portion, and second end portion according to a longitudinal axis, and comprising a central absorbent pad, a back sheet, a top sheet, and a perimetric edge comprising perimetric edges of the back sheet and the top sheet, the method comprising, in the following order, steps of:
folding elasticized segments of the perimetric edge located on sides of the incontinence pads opposed across the longitudinal axis down inwards onto the top sheet in the central portion, wherein non-elasticized segments of the perimetric edge remain unfolded during this folding step;
retaining the elasticized folded segments on the top sheet in the central portion;
folding each incontinence pad at a first and a second fold line both transversal to the longitudinal axis, the folding step comprising a first sub-step of folding the first end portion of the incontinence pad about the first fold line onto the top sheet in the central portion of the incontinence pad, and a second sub-step of folding the second end portion of the incontinence pad about the second fold line onto the first end portion; and
folding some of the non-elasticized segments of the perimetric edge towards the central absorbent pad,
wherein the distance between the first and second fold lines measured along the longitudinal axis of the incontinence pad is greater than or equal to the longitudinal dimension of the first end portion, and
wherein the elasticized folded segments are located between the first and second fold lines, and wherein, before being folded, the elasticized segments extend away from the central absorbent pad in the transverse direction no further than an extent in the transverse direction of non-elasticized segments of the perimetric edge along the same side of the central absorbent pad.

12. The method according to claim 11 , wherein the retaining step continues at least until the end of the first folding sub-step.

13. The method according to claim 11 , wherein the distance between the first and second fold lines is equal at least to one third of the longitudinal dimension of the entire incontinence pad.

14. The method according to claim 11 , wherein the step of some of the non-elasticized segments includes folding the non-elasticated segments of the perimetric edge between the first fold line and a first end of the incontinence pad and the non-elasticated segments of the perimetric edge between the second fold line and a second end of the incontinence pad around the first end portion and towards sides of the central portion of the central absorbent pad.

15. The method according to claim 11 , wherein the step of some of the non-elasticized segments includes folding the non-elasticized segments of the perimetric edge between the first fold line and a first end of the incontinence pad and the non-elasticized segments of the perimetric edge between the second fold line and a second end of the incontinence pad around the first end portion until they are superposed on sides of the central portion of the central absorbent pad.

16. A method for folding incontinence pads having a substantially rectangular shape, elongate and having a first end portion, central portion, and second end portion according to a longitudinal axis, and comprising a central absorbent pad, a back sheet, a top sheet, and a perimetric edge comprising perimetric edges of the back sheet and the top sheet, wherein the perimetric edge has substantially the same width around the entire periphery of the central absorbent pad, the method comprising, in the following order, steps of:
folding elasticized segments of the perimetric edge located on sides of the in
