The method, apparatus and material relate to the positioning of a cold seal adhesive on wrapping material for articles and rolls of articles. The material comprises a paper, plastics or foil substrate defining two surfaces, each of which have two edge regions, one region of each surface having the adhesive applied thereto so as to form a lap seal upon roll wrapping an article. The method of wrapping and wrapping apparatus involve the presentation of modified wrapping material and the subsequent overlying of one adhesive carrying edge section over the other to form a continuous contact seal along a longitudinal peripheral axis of the articles or rolls thus wrapped.

La présente invention concerne un procédé, un appareil et un matériau relatifs au dépôt d'un adhésif de soudure par pression à froid sur un matériau d'emballage pour articles et rouleaux d'articles. Ce matériau comprend un substrat en papier, plastique ou aluminium formant deux surfaces présentant chacune deux zones de bord, l'adhésif étant appliqué sur une zone de chaque surface de manière à former un scellage chevauchant lorsqu'un article est emballé en rouleau. Les procédé et appareil d'emballage impliquent la présentation d'un matériau d'emballage modifié, puis la disposition d'une partie de bord contenant l'adhésif sur l'autre pour former une soudure à contact continue sur la longueur d'un axe périphérique longitudinal des articles ou des rouleaux ainsi emballés.
