A method for preventing an increase in the number of defective absorbent articles in a method for manufacturing the absorbent article by processing a plurality of components including a plurality of continuous sheets while transporting the plurality of components in a plurality of transport paths, the method comprising: a generation step of generating a single composite sheet that is continuous in a transporting direction by completing in a predetermined merge completion position a merge process of all the continuous sheets of the plurality of continuous sheets; a generation step of generating the absorbent article by cutting the composite sheet at an interval in the transporting direction; a transport suspension step of suspending transport in the plurality of transport paths at an occurrence of a problem in a certain position in the plurality of transport paths; a standby step of bringing into a standby state at least some of processing devices among a plurality of processing devices located between the certain position where the problem has occurred and the merge completion position; a transport restart step of restarting the transport, after correcting the problem, while some of the processing devices are maintained in the standby state; and a restoration step of restoring to a processing state some of the processing devices in the standby state, after restarting the transport, wherein in a case of defining, as an uppermost-stream processing device as viewed in the transport direction, a processing device in a position with a greatest number of parts to compose the absorbent article, among all processing devices located upstream of the merge completion position in the transporting direction, the parts being placed between a position of each processing device and the merge completion position and including the parts in the middle of being processed with the processing device, the restoration step is performed such that a part for which processing is restarted in the restoration step passes the merge completion position before an uppermost-stream part, as viewed in the transport direction, reaches the merge completion position after the restart of the transport, the uppermost-stream part being a part that can be associated with the absorbent article among parts of the plurality of components, the uppermost-stream part being located in the uppermost-stream processing device during suspension of the transport. a generation step of generating a single composite sheet that is continuous in a transporting direction by completing in a predetermined merge completion position a merge process of all the continuous sheets of the plurality of continuous sheets; a generation step of generating the absorbent article by cutting the composite sheet at an interval in the transporting direction; a transport suspension step of suspending transport in the plurality of transport paths at an occurrence of a problem in a certain position in the plurality of transport paths; a standby step of bringing into a standby state at least some of processing devices among a plurality of processing devices located between the certain position where the problem has occurred and the merge completion position; a transport restart step of restarting the transport, after correcting the problem, while some of the processing devices are maintained in the standby state; and a restoration step of restoring to a processing state some of the processing devices in the standby state, after restarting the transport, wherein in a case of defining, as an uppermost-stream processing device as viewed in the transport direction, a processing device in a position with a greatest number of parts to compose the absorbent article, among all processing devices located upstream of the merge completion position in the transporting direction, the parts being placed between a position of each processing device and the merge completion position and including the parts in the middle of being processed with the processing device, the restoration step is performed such that a part for which processing is restarted in the restoration step passes the merge completion position before an uppermost-stream part, as viewed in the transport direction, reaches the merge completion position after the restart of the transport, the uppermost-stream part being a part that can be associated with the absorbent article among parts of the plurality of components, the uppermost-stream part being located in the uppermost-stream processing device during suspension of the transport.
