Press for producing a tampon

1. Press ( 1 ) for producing a tampon ( 8 ) by radially pressing an absorbent material by means of compression jaws ( 2 , 2 ′, 3 ) which have respective penetrating segments ( 4 , 5 ) for embossing grooves ( 9 , 10 ) into the absorbent material, wherein one compression jaw ( 3 ) the penetrating segment ( 5 ) of which is designed as a strip having flat lateral faces projecting into the compression space and one compression jaw ( 2 , 2 ′) the penetrating segment ( 4 , 4 ′) of which is designed as a rib having undulated lateral faces projecting into the compression space being alternately arranged and a projection of the strip onto a peripheral surface of the tampon ( 8 ) present in the compression space represents a straight line and a projection of the undulated rib onto the peripheral surface represents an undulated line.

2. Press according to claim 1 , wherein a strip at the leading edge ( 6 ) features recesses ( 7 ) corresponding to undulations of the ribs of directly adjacent penetrating segments ( 4 , 4 ′).

3. Press according to claim 2 , wherein two compression jaws ( 2 , 2 ′) with undulated ribs, having a compression jaw ( 3 ) with a straight strip arranged between them, provide an opposed course of their undulations.

4. Press according to claim 1 , wherein compression jaws ( 2 , 2 ′, 3 ) directly following after each other are each positioned from each other at an angle that is pre-determinable.

5. Press according to claim 4 , wherein two compression jaws ( 3 ) directly following one after another and having straight strips are positioned at 90° from each other and two compression jaws ( 2 , 2 ′) directly following one after another having undulated ribs are positioned at 90° from each other, too.

6. Press according to claim 1 , wherein the generatrix of the undulated ribs essentially extend normal to a longitudinal axis ( 1 ′) of the press ( 1 ).

7. Press according to claim 1 , wherein the compression jaws ( 2 , 2 ′, 3 ) are moveable in radial direction and straight to the longitudinal center axis of the press each.

8. Method for producing a tampon ( 8 ) by radially pressing an absorbent material by means of a press ( 1 ) with compression jaws ( 2 , 2 ′, 3 ) with the compression jaws ( 2 , 2 ′, 3 ) having respective penetrating segments ( 4 , 5 ) for embossing grooves ( 9 , 9 ′, 10 ) into the absorbent material, wherein one compression jaw ( 3 ) the penetrating segment ( 5 ) of which is designed as a strip having flat lateral faces projecting into the compression space and one compression jaw ( 2 , 2 ′) the penetrating segment ( 4 , 4 ′) of which is designed as a rib having undulated lateral faces projecting into the compression space being alternately arranged whereby a projection of the strip onto a peripheral surface of the tampon ( 8 ) present in the compression space represents a straight line and a projection of the undulated rib onto the peripheral surface represents an undulated line and for embossing grooves ( 9 , 10 ) the penetrating segments ( 4 , 5 ) are pressed onto the surface of the tampon ( 8 ) and after an embossing the grooves ( 9 , 10 ) onto the surface of the tampon ( 8 ) penetrating segments ( 4 , 4 ′) embodied as undulated ribs are retracted out of the absorbent material of the tampon ( 8 ), meanwhile penetrating segments ( 5 ) embodied as strips with flat lateral faces remain in the absorbent material as feedings for ejecting the tampon ( 8 ), out of the press.
