Abstract
The present invention is a method for manufacturing cleaning members obtained by cutting multi-layer webs formed by: spreading fiber bundles, the lengthwise directions of which are parallel to the direction in which said are conveyed; and layering together at least the spread and non-woven fabric strips. Said method includes a step in which, before spreading, two or more are joined together, forming one or more join sections. Said joins are performed by joining the back end (with respect to the conveyance direction) of one to the front end (with respect to the conveyance direction) of the next fiber bundle.
