The guide member includes: an arm member having a tip portion that is a feeding position of the elastic member to the web, and a base portion separated from the tip portion; a first drive member that swings the arm member about the base portion of the arm member as a rotational axis; and a second drive member that performs a back and forth movement of the arm member and the first drive member along a cross direction that crosses a conveyance direction in which the web is conveyed.

Abstract: An absorbent-body manufacturing apparatus manufactures an absorbent body by depositing absorbent-body material in a plurality of recess sections spaced at an arrangement pitch on an outer circumferential face of a drum. The apparatus has a driving source that drives the drum in synchronization with another apparatus based on a synchronization signal. First and second signal-generating sections repeatedly generate first and second rotational-angle signals based on a rotation of the drum with a rotational angle of the drum as a unit, the rotational angle of the drum corresponding to first and second pitches, respectively. Depending on whether the arrangement pitch is set to the first or second pitch, a controller controls rotational driving operation of the driving source based on the first or second rotational-angle signal and on the synchronization signal.

Abstract: In a defective-workpiece discharging device, a defective workpiece is discharged to a discharge path from a conveyance path that conveys a plurality of workpieces related to absorbent articles at a predetermined conveyance pitch. The conveyance path has a first path and a second path downstream of the first path. A sorting mechanism between the first and second paths sorts workpieces into either the second path or the discharge path. A defect detection sensor detects a defect and outputs a defect detection signal. A passage detection sensor detects passage of the workpieces at a predetermined position on the first path and outputs a passage detection signal. A controller controls the sorting mechanism based on the defect and passage detection signals. An end of the first path on the sorting mechanism side and the predetermined position are separated by a distance greater than or equal to the conveyance pitch.
