Abstract
A method for the manufacture of an applicator is described. The method is characterized in that: a) an application preform (5) is formed, b) at least one portion (50) of the preform (5) is transformed by machining, using a machining device (6) able to form in the preform (5) a plurality of typically transverse radial recesses (51) by removing material from the portion using a machining tool (60), thereby forming at least one machined component (7) fitted with a plurality of radial elements (70) of an application means (4), the machined component (7) being then, after cutting or possible lengthening, typically coupled to an axial rod (3).
