The material splicing device (20), the accumulating device (40) capable of accumulating the preceding material or the succeeding material continuously sent from the material splicing device in the form of a loop, and the first direction from the accumulating device as the transport direction A transport direction changing member (50) that changes the transport direction to a second direction that intersects the first direction in a plan view, and sends the preceding material or the subsequent material to be sent to the processing apparatus. The length of the transport path of the preceding material or the succeeding material from the joining position (Pj) where the succeeding material is joined to the material to the arrival position (P40a) reaching the accumulating device is transferred from the accumulating device. Absorbent article shorter than the length of the transport path of the preceding material or the succeeding material between the delivery position (P40d) delivered to the direction change member and the arrival position (P50a) reaching the transport direction change member Material supply equipment to be supplied to processing equipment .資材継ぎ装置（２０）と、資材継ぎ装置から連続して送られる先行の資材又は後行の資材をループの形態で蓄積可能な蓄積装置（４０）と、蓄積装置から第１方向を搬送方向として送られる先行の資材又は後行の資材を、平面視で第１方向と交差する第２方向に搬送方向を変更して加工装置へ送る搬送方向変更部材（５０）と、を有し、先行の資材に後行の資材を接合する接合位置（Ｐｊ）から、蓄積装置に到達する到達位置（Ｐ４０ａ）までの間の先行の資材又は後行の資材の搬送経路の長さは、蓄積装置から搬送方向変更部材へと送出される送出位置（Ｐ４０ｄ）から搬送方向変更部材に到達する到達位置（Ｐ５０ａ）までの間の先行の資材又は後行の資材の搬送経路の長さよりも短い、吸収性物品に係る加工装置に供給する資材供給装置。
