To provide a rewinding roll of a film rolled web that can reduce meandering of a plastic film involved in rewinding, and stably manufacture a packaging bag whose edge is suppressed from deviating, and a vertical filling/packaging facility provided with a rewinding roll.SOLUTION: A rewound roll, which sequentially rewinds belt-like plastic films from a film rolled web, is constituted of: a roll body holding the film rolled web, supported rotatably through a bearing; moving means, joined to an axial end of the roll body, which moves the roll body together with the film rolled web along a shaft center of the roll body; sensing means that senses center positions in a width direction of the belt-like plastic films just rewound; and a control part that makes the moving means move the roll body together with the film rolled web along the shaft center of the roll body, in accordance with information about the center positions sensed by the sensing means, and changes the center positions in the width direction of the belt-like plastic films involved in rewinding.SELECTED DRAWING: Figure 1 【課題】巻き戻しに係わるプラスチックフィルムの蛇行を小さくするとともに、耳ずれの軽減された包装袋を安定して製造できるフィルム原反の巻き戻しロールと、巻き戻しロールを備えた縦型充填包装設備を提供すること。【解決手段】フィルム原反から帯状のプラスチックフィルムを順次に巻き戻す巻き戻しロールであって、前記フィルム原反を保持し、軸受けを介して回転可能に支持されたロール本体と、該ロール本体の軸端につながり、該ロール本体をフィルム原反とともに、該ロール本体の軸芯に沿って移動させる移動手段と、巻き戻し直後の帯状プラスチックフィルムの幅方向の中心位置を検知する検知手段と、該検知手段にて検知された情報にしたがい該移動手段によって該ロール本体を該フィルム原反とともに該ロール本体の軸芯に沿って移動させて、巻き戻しに係わる帯状のプラスチックフィルムの幅方向の中心位置を変化させる制御部と、からなること。【選択図】図１
