METHOD FOR STRETCHING A WEB OF MATERIAL IN THE MANUFACTURE OF A LIQUID-ABSORBENT ARTICLE AND A DEVICE FOR STRETCHING THE WEB OF MATERIAL

摘要

Method and device for stretching a web (8) of material in the manufacture of a liquid-absorbent article, comprising 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. Said 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).
