The material related to the absorbent article is conveyed in the conveying direction in a state where the material is stretched over the entrance roll (41u) and the moving roll (41m) of the dancer unit (40), and the conveyed material is designated as the preceding material (3a). When the leading edge of the following material (3f) is joined to the preceding material, the succeeding material is connected to the preceding material, and is positioned at the reference position from the downstream end (P3) of the material passing portion that is passed to the inlet roll. In order to make the total length of the joint (3j) and the overlapping portion (3d) longer than the path length of the material to the upstream end (P4) of the material transfer portion that is passed over the moving roll of Material splicing method to cut material.吸収性物品に係る資材がダンサーユニット（４０）の入口ロール（４１ｕ）及び移動ロール（４１ｍ）に掛け渡された状態で資材を搬送方向に搬送し、搬送される資材を先行資材（３ａ）として先行資材に後行資材（３ｆ）の先端部を接合して先行資材に後行資材を繋ぎ、入口ロールに掛け渡された資材の掛渡し部の下流端（Ｐ３）から基準位置に位置するときの移動ロールに掛け渡された資材の掛渡し部の上流端（Ｐ４）までの資材の経路長よりも、接合部（３ｊ）及び重なり部（３ｄ）の合計長さが長くなるように、先行資材をカットする資材継ぎ方法。
