PCT No. PCT/DE93/01177 Sec. 371 Date Aug. 1, 1995 Sec. 102(e) Date Aug. 1, 1995 PCT Filed Dec. 8, 1993 PCT Pub. No. WO94/14607 PCT Pub. Date Jul. 7, 1994A multilayered elastic sheetlike structure and a process for producing it are described. The sheetlike structure consists of at least one elastomeric layer of a homogeneous film/sheet and at least one inelastic fibre or filament layer which is connected to the elastomeric layer at mutually spaced-apart connection sites. Between the connection sites the fibre or filament layer is in folds when the elastomeric layer is in an untensioned or partially tensioned state and smooth when the elastomeric layer is in the completely tensioned state. The inelastic fibre or filament layer consists of an originally smooth, undrawn or partially drawn material which has been melted or adhered to the untensioned elastomeric layer at the connection sites and, after conjoint extension therewith, exhibits a persistent extension.
