Abstract: A device and a corresponding method for shaping and/or smoothing at least one end of a tampon blank, in particular an axial end of a tampon blank, includes a guide unit driven by at least one shaft. The guide unit includes first and second conveyor planes. The device also includes shaping sleeves on the second conveyor plane for receiving at least one respective tampon blank, and rotatable shaping caps on the first conveyor plane, each designed to be operatively connected to at least one end of a tampon blank in a shaping sleeve. The first conveyor plane and the second conveyor plane are designed in order to guide a respective at least one of the shaping sleeves on the second conveyor plane coaxially relative to at least one of the rotatable shaping caps on the first conveyor plane on the conveyor plane. A computer program product controls the device.

Abstract: A method for winding preforms for the manufacture of tampons feeds a material tape. Strips in the form of tapes are separated from this material tape and pushed into a continuously rotating winding drum by at least one drive roller in such a way that the strip is positioned between a winding fork and a guide bar such that when the winding fork moves around the guide bar, the latter pushes a section of the strip into a fork gap of the winding fork and thus enables entrainment. Also, a corresponding device carries out the method.

Abstract: The present invention relates to an apparatus for forming tampons, which comprises a plurality of processing drums 2, 4, 5.1, 5.2 for forming a tampon from band-form material. It also comprises at least one transfer station 7 for continuously transferring a preform from a first processing drum 2, 4, 5.1, 5.2 to a second processing drum 4, 5.1, 5.2. The invention also relates to a method for forming a tampon from band-form material, wherein transfer from a first processing drum to a second processing drum takes place by means of a continuously rotating transfer wheel.
