A feed roller mechanism that feeds a continuous paper while nipping the continuous paper between a first roller and a second roller that face each other, the feed roller mechanism includes a plate-shaped first support member that supports the first roller, and a plate-shaped second support member that supports the first support member, wherein the first roller nips the continuous paper with the second roller by a deflection reaction force of the first support member.

A method is presented for making a multizone sticker for manufacturing an absorbent article. The method includes unwinding a sticker laminate. The method also includes separating the laminate into a first layer and a second layer, with the first layer including a surface with adhesive and the second layer including a non-stick backing layer. The method also includes treating the first layer with adhesive neutralizing agent to form a first zone with untreated adhesive and a second zone with treated adhesive. The method also includes recombining the first layer and the second layer, with at least a portion of the first zone configured to extend across a leading edge of a roll of material comprising a roll winding direction.

A stacking device for stacking substrates includes: a frame; an input region; an output region; and at least one conveying element mounted on the frame so as to be completely rotatable about an axis of rotation. The at least one conveying element has a gripping portion for conveying a substrate located in the input region to the output region.
