Abstract:
1. Method of applying one or more twin fastener portions 10 a to an absorbent article 1 and, in particular, to a disposable diaper, said absorbent article 1 comprising a top sheet web 2 having an inner surface 2 a , an outer surface 2 b , a first lateral edge 2 c and a second lateral edge 2 d , a back sheet 3 having an inner surface 3 a , an outer surface 3 b , a first lateral edge 3 c and a second lateral edge 3 d , an absorbent core 4 arranged between said top sheet 2 and said back sheet 3 , said twin fastener portion 10 a comprising a first manufacturer's end 11 a , a first user's end 12 a , a releasable connection 19 , a second user's end 12 b and a second manufacturer's end 11 b , wherein the dimensions of the manufacturer's ends 11 a , 11 b , the user's ends 12 a , 12 b and the releasable connection 19 in cross-direction being selected so that the manufacturer's ends 11 a , 11 b can be positioned adjacent to opposite lateral edges 2 c , 2 d and/or 3 c , 3 d of the top sheet 2 or the back sheet 3 , respectively, and wherein the releasable connection 19 can be released to provide two separate fastener portions 10 , said method comprising in a first alternative (A) the steps of: (i) providing a top sheet (ii) placing the one or more twin fastener portions (iii) folding around the manufacturer's ends (iv) applying an absorbent core whereby the sequence of steps (ii) and (iii) or (iii) and (iv), respectively, may be exchanged, or in a second alternative (B) (i) providing a back sheet (ii) placing the one or more twin fastener portions (iii) folding around the manufacturer's ends (iv) applying an absorbent core whereby the sequence of steps (ii) and (iii) or (iii) and (iv), respectively, may be exchanged and wherein the top sheet 2 in the first alternative (A), step (ii) comprises a fold 2 e or wherein the back sheet 3 in the second alternative (B), step (ii) comprises a fold, respectively, whereby such folds are straightened out in subsequent steps during or after the application, respectively, of the twin fastener portion 10 a , by exerting a force in cross direction on at least the top sheet 2 or the back sheet 3 , respectively, thereby breaking the twin fastener portion 10 a into two separate fastener portions 10 .
