CA 2236854

A method of surface winding of a web material (N) to form a roll (L) is described, in which, at the end of the winding of the said roll (L), the web material is severed to form a free tail edge (LL) and a free leading edge for the start of a subsequent roll. The completed roll is discharged directly from the winding area (83, 85, 87) onto gluing means which apply an adhesive to the wound material. The free tail edge (LL) is rewound and covers the applied adhesive while the roll is discharged.

On décrit un procédé d'enroulement sur une surface d'un matériau en feuille continue (N), afin de former un rouleau (L), ce procédé consistant, à la fin de l'enroulement du rouleau (L), à couper le matériau en feuille afin de former un côté arrière libre (LL) et un côté avant libre, ce dernier servant au démarrage de l'enroulement d'un rouleau suivant. Le rouleau achevé est déchargé directement de la zone d'enroulement (83, 85, 87) sur des moyens colleurs, lesquels appliquent un adhésif sur le matériau enroulé. Le côté arrière libre (LL) est alors enroulé et il recouvre ainsi l'adhésif appliqué, tandis que le rouleau est déchargé.
