Abstract
A method for folding pads shaped as pants includes providing a first wing and a second wing of a pad with hook and loop elements, overturning the first and the second wing by 180° on the plane of the pad, and maintaining the first and the second wing in such position until the pad having the shape of pants is closed.
Claims14
A method for folding a semifinished product of an absorbent product for sanitary use to develop a product having a shape of pants, the semifinished product comprising:
- a first wing disposed on a first side and at or adjacently to a first longitudinal end of the semifinished product,
- a second wing disposed on a second side opposite to the first wing and at or adjacently to the first longitudinal end of the semifinished product, the first wing and the second wing comprising first quick connection elements,
- a third wing disposed on a same side as the first wing and at or adjacently to a second longitudinal end of the semifinished product opposite to the first end, and
- a fourth wing disposed on a same side as the second wing and at or adjacently to the second longitudinal end of the semifinished product opposite to the first end, the third wing and the fourth wing comprising second complementary quick connection elements,
- the method providing for a movement of the semifinished product along a processing path, the method comprising the following steps, along the processing path:
- folding the first wing and the second wing so as to lift the first wing and the second wing and overturn the first wing and the second wing on a plane of the semifinished product until reaching an overturned position, thereby causing the first quick connection elements of the first wing and the second wing to face an outside of the plane of the semifinished product;
- maintaining the first wing and the second wing in the overturned position;
- and
- folding the semifinished product transversally so as to respectively engage the first wing to the third wing and the second wing to the fourth wing by causing the first quick connection elements to engage the second complementary quick connection elements,
- further comprising a step of adjusting a width of at least one portion of the semifinished product so that the folded first wing and the folded second wing are longitudinally aligned with the third wing and the fourth wing.

- folding the semifinished product transversally so as to respectively engage the first wing to the third wing and the second wing to the fourth wing by causing the first quick connection elements to engage the second complementary quick connection elements,
- wherein causing the first wing and the second wing to overturn on a surface of the semifinished product comprises:
- lifting the first wing and the second wing through an airflow;
- and
- a subsequent folding that completes overturning,
- thereby causing both the first wing and the second wing to complete rotation until reaching a laid position on the plane of the semifinished product.
