Abstract
Method and device for stretching a web (8) of material in the manufacture of a liquid-absorbent article, having an absorption body (4) and a cover enclosing the same. The article is made from the web (8) of material being fed in its longitudinal direction, on which web one or more elongated elastic members (11-14) are fastened. The members extend at an angle to the longitudinal direction of the web and thereby subject the web to forces which are directed transversely to the longitudinal direction of the web. The web (8) of material is kept stretched in its longitudinal direction as well as in its transverse direction by mechanical restraint of the web of material adjacent to its longitudinal edge-portions (19,20).
