ABSTRACT:
A nozzle having a flexible blade member with a flat adhesive-receiving surface in combination with a rotary transfer roll and side wall elements forms a reservoir for adhesive "upstream" (in the direction of roll rotation) of the line of contact of a straight edge of the surface with the roll surface, the arrangement being such that a layer of the adhesive, doctored by blade member to control its thickness and with its width controlled by the wall elements, is applied to the roll surface and carried thereby to the operating locality. An adhesive supply system is also provided for supplying adhesive to the reservoir, said system including a melting device for adhesive in solid form and pressure control means for controlling the pressure under which the adhesive is supplied.
