Abstract
A method for producing a flexible sheet includes a stretching step in which a base sheet (10) is fed from between a pair of first drive rollers (42, 43) into the bite of a pair of intermeshing corrugated rollers (2, 3) and stretched in the machine direction between the corrugated rollers (2, 3). In the method, the peripheral velocity V1 of the first drive rollers (42, 43) and the peripheral velocity V2 of the corrugated rollers (2, 3) have a relation of V1>V2.
Claims5
A method for producing a flexible sheet comprising a stretching step in which a base sheet is fed from between a pair of first drive rollers into the bite between a pair of intermeshing corrugated rollers to be stretched in the machine direction,
- the peripheral velocity V1 of the first drive rollers and the peripheral velocity V2 of the corrugated rollers having a relation of V1>V2, and
- the ratio of the peripheral velocity V2 of the corrugated rollers to the peripheral velocity V1 of the first drive rollers (V2/V1)*100, is 60% to 90%.
