The invention relates to a method for a shaping step completing a process for producing a tampon (1) which is produced of an absorbent material. At least one groove (12, 13) is embossed onto the peripheral surface by radially compressing, preferably under thermal influence, at least one region of the tampon (1) extending along a peripheral surface of the tampon (1), the groove plane substantially extending normal to the longitudinal extension of the tampon.
