Abstract: A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an operation robot which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives the standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.

Abstract: An absorbent article processing device includes a cutter roll and an anvil roll. The cutter roll includes a roll main body; a blade protruding in a radial direction in a first angular range of a part of a circumferential direction of the roll main body; a first bearer protruding in the radial direction in a second angular range of a part of the circumferential direction including at least the first angular range and being in contact with the anvil roll, and being cut out in an angular range excluding the second angular range at a first end portion in an axial direction of the roll main body; and a second bearer provided around the entire circumference or a part of the circumferential direction and being in contact with the anvil roll at the second end portion in an axial direction of the roll main body.

Abstract: A holding region includes a first area bearing on at least part of one and at least part of the other of opposite skirt portions in a revolution direction of a holding pad, the first area extending along a first curve, when the holding pad is at a first revolution position. The holding region formed in the holding pad includes a second area bearing on at least part of one side portion and at least part of the other side portion in the revolution direction of the holding pad when the holding pad is at a second revolution position that extends along a second curve. The holding region includes a portion other than the first area and the second area that lies closer to a second rotational axis than the first curve and the second curve.

Abstract: A joining unit includes: a suction holding member having a suction surface configured to suction an end section of a sheet; a moving mechanism configured to move the suction surface toward an intermediate section of a sheet of a delivery-side original material roll along a path set in advance so that tension is applied to the sheet; and a regulating mechanism that is configured to switch between a regulated state in which a movement of the end section of the sheet with respect to the suction holding member due to the tension is regulated and an allowable state in which the movement of the end section of the sheet with respect to the suction holding member is allowed. The controller switches the regulating mechanism to the regulated state during the movement of the suction surface toward the intermediate section of the sheet of the delivery-side original material roll.
