22. ABSTRACT OF THE DISCLOSURE ADHESIVE APPLYING APPARATUS A nozzle (14) having a flexible blade member (16) with a concave adhesive-receiving surface (48) in combination with a rotary transfer roll (12) having a convex portion (20A) and side wall elements (18) forms reservoir for adhesive "upstream" (in the direction of roll rotation) of the line of contact of an applying edge (52) of said surface (48) with the surface of the convex portion of the roll, the arrangement being such that a layer of the adhesive, doctored by blade member (16) to control its thickness and with its width controlled by the wall elements (18), is applied to the roll surface and carried thereby to the operating locality (10). By selecting, for the convex portion of the roll, a material which is deformable, but in a readily controllable manner, by the operator pressing the surface of a workpiece to be coated against the surface of the convex portion, a desired degree of surface contact between the two surfaces, and thus a desired width of adhesive coating, can be readily achieved.
