At this, each treatment step (S1 is to S6) of handling fleece 7 before (especially before just will handling) execution transfer step make it possible to the fleece 7 that does not have fold is applied said processing.Like this, transfer step can guarantee to reduce the defect of fabrication of absorbent commodity 1, prevents production line stop.
At this, when seeing on the direction of transfer MD at fleece 7, press surface 111A is rectilinear.Utilize press surface 111A, just will carry out each processing (for example, any one among the S1-S6) before, fleece 7 is drawn as smooth state.In other words, the fleece 7 that is adjusted into and remains on smooth state by press surface 111A is applied said processing.As a result, can guarantee to reduce the defect of fabrication of absorbent commodity 1 more.
At this, conveyer 100 also comprises connecting gear 120 except pressing mechanism 110.Connecting gear 120 can guarantee to prevent that the fleece 7 from pressing mechanism 110 belows are passed through from shrinking to the center on Width CD.Particularly, belt conveyor 121 is pressed to the lateral margin 10A and the lateral margin 20A of fleece 7 in flanging unit 124, thereby can guarantee more to prevent that stretchable fleece 7 from shrinking to the center on Width CD.As a result, can guarantee more to prevent to produce fold at fleece 7.
At this, the width (w) of pressing plate 111 on Width CD in the downstream greater than upstream side.According to such structure, the fleece 7 in transmitting from pressing mechanism 110 belows through the time, the fleece 7 that contact with the pressing plate 111 plate 111 outwards stretching on Width CD that is pressed.Like this, can guarantee to eliminate any fold that produces at fleece 7 more.
