1. A manufacturing apparatus for manufacturing an absorbent article using a composite sheet,
the composite sheet being associated with the absorbent article, the composite sheet including a stretchable sheet and a low-extensible sheet, the low-extensible sheet being stacked on the stretchable sheet from a thickness direction and being fixed to the stretchable sheet, and the low-extensible sheet having an extensibility lower than that of the stretchable sheet, the composite sheet continuing along a predetermined direction, the composite sheet being transported in the predetermined direction that is defined as a transporting direction, the manufacturing apparatus comprising: a cutter apparatus that includes: a cutter blade that abuts the composite sheet from a side closer to the stretchable sheet; a receiving section
that have a surface area andthat receives the cutter blade while abutting the composite sheet from a side closer to the low-extensible sheet,a cutter-blade rotating member having the cutter blade that protrudes on an outer circumferential surface of the cutter-blade rotating member; anda receiving-section rotating member having the receiving section on an outer circumferential surface of the receiving-section rotating member,the cutter apparatus cutting the composite sheet,
the cutting of the composite sheet being performed by passing the composite sheet in the transporting direction between the cutter-blade rotating member and the receiving-section rotating member while the cutter-blade rotating member and the receiving-section rotating member are rotating along the transporting direction with their outer circumferential surfaces facing each other,the cutter apparatus forming a leg opening of the absorbent article as a physical reference section on the composite sheet,
the forming of the leg opening being performed by cutting the composite sheet that is being transported along the transporting direction,
the composite sheet being in a first extended state in which the composite sheet extends in the transporting direction; a contraction apparatus in which the composite sheet that has the reference section formed on it contracts until the composite sheet becomes in a second extended state whose extension ratio is smaller than an extension ratio of the first extended state; and a processing apparatus that performs a certain process to the composite sheet,
the composite sheet having contracted and being in the second extended state, wherein the contraction apparatus includes:
a transport path in which the composite sheet is transported;a sensor
that detects the reference section after the contraction in the contraction apparatus andthat outputs a detection signal; andan alteration device that alters a transportation state of the composite sheet in the transport path so that a position in the composite sheet for the certain process is located close to a target position for the certain process,
the alteration being performed according to the detection signal of the sensor. |
