The device comprises a glue roller which picks up adhesive from a tray or tank, a scraper that wipes the glue roller, leaving the adhesive at prescribed points only, and a contact roller which takes sheets of wrapping material through an area where adhesive is applied to them. The contact roller is disposed about an axis parallel to the axis of the glue roller through positioned downstream thereof in the direction of movement of the sheets, such that a guide may be located beneath the contact roller adjacent to the cladding of the roller, designed to afford support to sheets carried by the contact roller and existing from the area where the adhesive is applied. |
