## Abstract

The transport method includes a speed varying step of varying speed of a first holding portion between a receiving position and a predetermined relay position by means of a speed change mechanism; a control step of controlling speed of a servo motor for driving rotation of second holding portions, such that speed of the second holding portions becomes a receiving speed at which the second holding portions is able to receive the absorbent body from the first holding portion at the relay position and becomes a predetermined transfer speed at a transfer position, and such that the second holding portions arrive at the relay position and at the transfer position at a predetermined cycle; and a speed changing step of changing the transfer speed while the cycle is maintained.

## Claims

### Claim 1

A method of manufacturing a disposable wearable article having a basic part and a processing part joined on the basic part, the method comprising:
a web transport step of transporting a basic part web for forming the basic part;
a processing part transport step of transporting the processing part from a predetermined receiving position to a predetermined transfer position, such that the processing part is received at the receiving position and transferred, at the transfer portion, onto the basic part web that is being transported in the web transport step;
a joining step of joining the processing part to the basic part web; and
a cutting step of cutting the basic part web to the basic part, wherein
the processing part transport step includes:
a speed varying step of varying a speed of a first holding portion between the receiving position and a predetermined relay position by means of a speed change mechanism, the first holding portion being configured to receive the processing part at the receiving position, the speed varying step being carried out by rotating, at constant speed, a drive wheel on which the first holding portion is supported via the speed change mechanism, the speed changing mechanism including a crank arm rotatably attached to the drive wheel, a link rotatably attached to the crank arm and the first holding portion, and a fixed member formed with a speed-changing cam groove for swinging the crank arm;
a control step of controlling a speed of a servo motor for driving rotation of a second holding portion that is configured to hold the processing part, such that a speed of the second holding portion becomes a receiving speed at which the second holding portion is able to receive the processing part from the first holding portion at the relay position and becomes a predetermined transfer speed at the transfer position, and such that the second holding portion arrives at the relay position and at the transfer position at a predetermined cycle; and
a speed changing step of changing the transfer speed while the cycle and the receiving speed are maintained, and wherein,
in the web transport step, a transport speed of the basic part web is changed in accordance with the changed transfer speed after changing the transfer speed while the cycle and the receiving speed are maintained in the speed changing step.

### Claim 2 (depends on 1)

The method of manufacturing a disposable wearable article according to claim 1, further comprising an application step of applying an adhesive to at least one of the basic part web and the processing part, wherein
the basic part web and the processing part are joined together by the adhesive in the joining step.

### Claim 3 (depends on 2)

The method of manufacturing a disposable wearable article according to claim 2, further comprising a through hole forming step of forming a plurality of through holes in the basic part web at a distance in a transport direction of the basic part web, wherein
the processing part and the basic part web are joined together in the joining step in a state where the processing part is placed between two adjacent through holes such as to cover inner side portions of the two through holes, and
in the application step, the adhesive is applied before the through hole forming step in areas other than regions where the through holes are to be formed in the basic part web.

### Claim 4 (depends on 3)

The method of manufacturing a disposable wearable article according to claim 3, wherein the processing part is bonded to the basic part web in the joining step such that both ends of the processing part are placed on outer sides of the through holes in a web width direction orthogonal to the transport direction of the basic part web, and
in the application step, the adhesive is applied before the through hole forming step to two web-side bonding positions on the basic part web where both ends of the processing part in the web width direction are placed, and the adhesive is applied before the joining step to a portion of the processing part, which is a portion other than a portion that covers the through holes and is placed between the web-side bonding positions.

### Claim 5 (depends on 4)

The method of manufacturing a disposable wearable article according to claim 4, wherein, in the speed varying step, both ends of the processing part in the web width direction on a surface applied with the adhesive are held by suction by the first holding portion, and
in the control step, a surface opposite to the surface applied with the adhesive of the processing part is held by suction by the second holding portion.

### Claim 6 (depends on 2)

The method of manufacturing a disposable wearable article according to claim 2, wherein, in the application step, the adhesive is applied at least to the processing part among the basic part web and the processing part, and
in the speed varying step, a portion of the processing part on a surface applied with the adhesive other than an adhesive-applied portion is held by suction by the first holding portion, and
in the control step, a surface opposite to the surface applied with the adhesive of the processing part is held by suction by the second holding portion.
