An apparatus () for producing stretchable sheet of the present invention includes a pair of conveyance belts () which is separately arranged, elastic body winding means () which winds a threadlike elastic body () around the pair of conveyance belts () and orients the threadlike elastic body () to a direction intersecting with a conveyance direction of continuous-length sheets, and integrating means which fixes the threadlike elastic body () to the continuous-length sheets. The conveyance belts () include upper belts () and lower belts (). Proceeding portions (') which convey the threadlike elastic body () at respective upper belts are inclined so that an upper side is located closer than a lower side to a center position (PC) between the conveyance belts, and proceeding portions (&#x2032;) which convey the threadlike elastic body () at respective lower belts are inclined so that a lower side is located closer than an upper side to a center position (PC).

Apparatus for manufacturing stretchable sheet

A method for producing a flexible sheet includes a stretching step in which a base sheet () is fed from between a pair of first drive rollers () into the bite of a pair of intermeshing corrugated rollers () and stretched in the machine direction between the corrugated rollers (). In the method, the peripheral velocity Vof the first drive rollers () and the peripheral velocity Vof the corrugated rollers () have a relation of V&#x3e;V

Method for producing flexible sheet

A stretchable composite sheet having a number of ridges in a neat and orderly arrangement is disclosed. The stretchable composite sheet is easily produced by the process of the invention. The stretchable composite sheet is a laminate of a stretch sheetand a nonstretch sheet. The stretch sheethas first zoneshaving elastic stretchability and second zoneshaving less stretchability than the first zones. The first zonesand the second zonesextend in the same direction and alternate with each other. The stretch sheetand the nonstretch sheetare bonded over substantially the entire area of their facing sides. The stretchable composite sheet has a large number of ridgeson the side of the nonstretch sheet.

Stretchable composite sheet

A method of producing a clothing article including the steps of (a) joining first continuous websandhaving stretchability in the longitudinal direction thereof both in a longitudinally stretched state along an edge portion thereof to a longitudinally substantially inextensible second continuous webto make a continuous composite sheet, (b) joining the composite sheetobtained in step (a) on its side to a memberof the clothing article to make a web assembly, and (c) cutting the web assemblyobtained in step (b) to length.
