Abstract
A method and apparatus for producing pant-like absorbent sanitary articles with longitudinal elastic bands without side welds, wherein a length of the elastic bands is different from a length of an absorbent body.
Claims8
A method for producing absorbent sanitary articles, comprising:
- forming absorbent bodies elongated along a longitudinal axis, and having respective longitudinal sides,
- forming elastic bands,
- coupling the elastic bands and the absorbent bodies to each other parallel to said longitudinal axis at the longitudinal sides of absorbent bodies, and
- fixing the elastic bands and the absorbent bodies together along two front and two rear inclined joint lines,
- wherein the method further comprises the step of forming transverse loops on said absorbent bodies and/or on said elastic bands before fixing the elastic bands and the absorbent bodies together, so as to form absorbent sanitary articles provided with elastic bands having a length in an extended condition that is different from a length in an extended condition of the respective absorbent bodies.
