ABSTRACT:
A method is proposed for producing a tampon (T) packaged in a protective sleeve made from a preform (V) which is preferably formed by winding a strip of fibrous non-woven material. The preform (V) is shaped to form the tampon in separate pressing stages by pressure forces acting on it from outside, and is individually packaged by providing it with a film sleeve (10) tightly enclosing the tampon (T) serving as a protective sleeve.In order to reduce the complexity involved in producing a tampon, and in particular a non-round tampon, to the point at which its is individually packaged in the protective sleeve, the substantially cylindrical preform (V) is already paced in the film sleeve (10) surrounding at least the external surface of the preform (V) before the final forming stage (15). The preform (V) including the film sleeve (10) surrounding it is then fed to the final stage (15), where it is formed between at least two pressing jaws (20a,20b) which can be displaced relative to on another until it has assumed its final non-cylindrical shape.
