Abstract
It is possible to achieve reduction in the occurrence of tension decrease at fiber bundles in a sheet. A method of manufacturing a tank includes several steps. A feed step is carried out of feeding a sheet including aligned fiber bundles while applying tension to the sheet in the longitudinal directions of the fiber bundles. The method further includes a detection step of detecting a decreased tension part subjected to tension decrease in the sheet being fed and a tension recovery step of compensating for the tension decrease at the decreased tension part by spraying an organic solvent if the decreased tension part is detected in the detection step. The method also includes a winding step of winding the sheet having been fed on a liner.
