Abstract
Method and apparatus for attaching elastic bands to a web comprised of absorbent articles such as diapers which are fabricated to lie transversely of the length of a continuous fabrication line. The bands are stretched in a direction transverse to the fabrication line and are attached to the web in their stretched condition and are maintained in stretched condition transversely to the web until the article is fabricated.

A method of attaching elastic bands to flexible absorbent articles such as diapers comprising the steps of forming the articles in a continuous web comprising the articles which web extends longitudinally and is travelling longitudinally along a fabrication line and the length of the individual articles in the line is transverse to the longitudinally extending web, stretching elastic bands in a direction such that the longitudinal axes of the bands are transverse to the longitudinal travel direction of the web, attaching said bands to the web in their stretched condition and maintaining said bands in stretched condition transversely to the web until fabrication of the article in the web is completed and then allowing the bands to contract and pleat the article.
Apparatus for attaching elastic bands to a web composed of absorbent articles and comprising means for fabricating the web and in a continuous fabrication line in which a layer of pad material extends longitudinally along said fabrication line and the length of individual articles is transverse to the longitudinal direction of the web, means for stretching elastic bands in a direction such that the longitudinal axes of the bands are transverse to the longitudinal direction of the web, means for attaching said bands to the web in their stretched condition and for maintaining said bands in stretched condition transversely to the web until the articles composing the web are fabricated, and means for enabling the attached bands to contract to pleat the web.
