Zusammengesetzte elastische Bahn für Hygieneartikel, ihr Herstellungsverfahren und ihre Verwendung

摘要

This invention provides an exceptionally expandable sheet elastic complex which consists of an elastic body sheet (1) and a sheet backing material (2) which is mounted on either one or both sides of it, these two members being bonded together along multiple, oblong, mutually parallel bonding sections (3), and in which multiple, mutually parallel channels (4) are formed between the two members because the width of the sheet backing material between mutually adjacent bonding sections is greater than that of the elastic body sheet. The sheet backing material does not accept more than the minimum constraint of the elastic body sheet, and its waveform surface has excellent properties as a material for use in sanitary products. The invention also provides a process for manufacturing this sheet elastic complex.
