Patent

CA 2492999

A first web 65 comprises a series of sheet members contiguous to one another in a transverse direction of this web, each of the sheet members defining an outer surface of a disposable wearing article 1, is continuously fed in a first machine direction MD1. A second web 367 presenting a .OMEGA.-shaped cross-section and configured to form individual adhesive taper strips is fed in a second machine direction MD2 orthogonal to the first machine direction MD1. The second web 367 is periodically cut in a second cross direction CD2 orthogonal to the second machine direction MD2 to obtain composites 67 configured to be a pair of the adhesive tape strips. After the composite 67 has been fed in the second machine direction MD2 and attached to the first web 65, the first web 65 is cut together with the composite 67 so as to bisect the length of the composite 67. Respective halves of the composite 67 bisected in this manner become the individual adhesive tape strips.

L'invention concerne une première bande (65), dans laquelle un élément de feuille formant la surface extérieure d'un vêtement jetable (1) est continue dans le sens transversal. Cette première bande (65) est amenée en continu dans un premier sens machine (MD1). Une seconde bande (367) formant une pièce de bande adhésive dont la section est en forme de OMEGA est amenée en continu dans un second sens machine (MD2) perpendiculaire au premier sens machine (MD1) et chaque fois qu'un temps prédéterminé s'écoule, la seconde bande (367) est découpée dans un second sens transversal (CD2) perpendiculaire au second sens machine (MD2) afin de donner un corps composite (67) de pièce de bande adhésive. Ce corps composite (67) est amené depuis le second sens machine (MD2) et fixé à la première bande (65) de façon que la longueur du corps composite (67) soit coupée en deux. Un dispositif de fixation de la bande adhésive est formé à partir du corps composite (67) coupé.
