A method of producing a he1ically-grooved, liquid applicator roller includes winding filaments around a cylindrical blank, A multi-start winding is constrained so that adjacent fila-ments touch. In the example shown in the drawing, a three start winding consisting of filaments 1, 2 and 3 is wound on a cylindrical blank 4. Filaments 2 and 3 are then removed, whereas filament 1 is made to adhere to the blank, This may be achieved by making the filaments of different materials so that the filament which is to remain adheres to the blank, for example, by the use of adhesives, or by heat curing while the others do not, Alternatively, the filaments which are to be removed may be dissolved, Typical materials for the filaments are polyamides and metals.
