Abstract
A method for producing pant-like absorbent sanitary articles, wherein a plurality of absorbent bodies are attached to a single continuous elastic band, which is cut to form a plurality of absorbent sanitary articles in an outspread configuration, which are then folded in a closed pant-like configuration.
Claims15
A method for producing refastenable pant-like absorbent sanitary articles, comprising:
- providing a single continuous elastic band having a longitudinal direction,
- providing a plurality of absorbent bodies having respective main directions and first and second end portions,
- orienting said plurality of absorbent bodies with the respective main directions transverse to the longitudinal direction of said single continuous elastic band,
- attaching the first end portions of said plurality of absorbent bodies to said single continuous elastic band in positions spaced apart from each other along said longitudinal direction, with the main directions of the plurality of absorbent bodies extending transversally to said longitudinal axis,
- cutting said single continuous elastic band to form a plurality of refastenable absorbent sanitary articles in an outspread configuration, each including:
- an absorbent body of the plurality of absorbent bodies having the main direction and the first and second end portions,
- a single elastic waistband attached to the first end portion of the absorbent body and having two elastic lateral bands projecting laterally from the absorbent body,
- folding each absorbent body and overlapping the second end portion to the first end portion, and
- folding the two elastic lateral bands of each absorbent sanitary article of the plurality of absorbent sanitary articles in the outspread configuration and attaching distal ends of said two elastic lateral bands to respective engagement areas of the second end portion of the absorbent body to form a refastenable absorbent sanitary article closed in a pant-like configuration.

An apparatus for producing refastenable pant-like absorbent sanitary articles, comprising:
- a conveyor configured for advancing a single continuous elastic band in a longitudinal direction,
- a cutting unit configured for forming a plurality of absorbent bodies having respective main directions and first and second end portions,
- a turn-and-repitch unit configured for orienting absorbent bodies of said plurality of absorbent bodies with the respective main directions transverse to the longitudinal direction of said continuous elastic band and for attaching first end portions of said absorbent bodies to said single continuous elastic band in positions spaced apart from each other along said longitudinal direction, with the main directions of the absorbent bodies extending transversally to said longitudinal direction,
- a rotating knife configured for cutting said single continuous elastic band to form a plurality of absorbent sanitary articles in an outspread configuration each having an elastic waistband attached to a respective absorbent body and two elastic lateral bands projecting laterally from the respective absorbent body, and
- a folding unit configured for folding the absorbent bodies and two elastic lateral bands of each of said absorbent sanitary articles in the outspread configuration to form refastenable absorbent sanitary articles closed in a pant-like configuration.
