A system and method for tearing off and rolling up a strip of absorbent fiber sheet for a tampon are discussed. An endless absorbent fiber sheet is propagated with a first linear speed by a first pair of rolls, and with at least the first linear speed by a second pair of rolls. A pulling means is provided to induce a second linear speed in the sheet larger than the first linear speed for tearing off a strip from the sheet. The first pair of rolls is configured to maintain the first linear speed of the absorbent fiber sheet, while the second pair of rolls is configured to rotate in a freewheel-type manner when the absorbent fiber sheet is pulled through the second pair of rolls at linear speeds larger than the first linear speed. Preferably, the pulling means is a rotatable clamping means for rolling up the strip.

An absorbent tampon is disclosed herein. The absorbent tampon strikes a balance between fluid distribution and expansion to reduce the likelihood of kinetic leakage and bypass leakage. The tampons have a fluid kinetic value FKV and a dynamic expansion value which are associated with their respective Syngyna ratings.

The invention relates to a method for the manufacture of a tampon (1) having at least one absorbent body made from an absorbent material (6), the tampon (1) having a proximal end (2) and a distal end (3) and a middle part extending between the distal end and the proximal end, as well as an extraction means (5) connected to the absorbent body and situated at the distal end (3), and the tampon has a covering made from a nonwoven material (4), which, with the exception of a pass-through opening (13) for the extraction means (5), completely covers at least the distal end (3), by which the escaping of fibers at the distal end (3) is prevented, and the covering additionally forming a protection against the fluid leakage.

A tampon with an absorbent body of which at least a part of its volume is made from an absorbent material and having a middle part, a distal end and a proximal end, and which is connected to an extraction device. The volume of absorbent material in such a tampon is designed to absorb between 0.5 g and 4 g, preferably 3.5 g, of liquid.

A sanitary tampon that includes a body of generally cylindrical shape provided with a rounded front end in the insertion direction of the tampon and with a rear end from which an extraction cord protrudes; the body including an absorbent core, rectangular, with two major sides and two minor sides, covered with an absorbent sheet of non-woven fabric, and wound in the longitudinal direction and pressed together with said absorbent sheet, its major sides being oriented towards the front and rear ends of the body of the tampon and the tampon being made entirely of natural materials.

Aspects of the present disclosure relate to methods for making tampons including primary absorbent members and secondary absorbent members. In some configurations, the tampons may be constructed with a primary absorbent member formed by a primary absorbent pad in a rolled configuration. In some configurations, the tampons may be constructed with a primary absorbent member formed by first and second primary absorbent pads positioned in a crossing configuration.

A tubular shaped tampon can include an absorbent body defining a cylindrical shape having a hollow interior, a porous protective sleeve surrounding the absorbent body, and a string that holds the protective sleeve in place against the absorbent body and facilitates removal of the tampon after use. The absorbent body and protective sleeve can combine to define an overall tubular structure having an inner hollow region, providing increased surface area. Methods of manufacturing the tampon can include cutting a fluid absorbent material, rolling the cut material around elongated machine prongs to form an absorbent body, rolling a porous sheet around and extending beyond both distal ends of the absorbent body, pinching together distal ends of the porous sheet, pushing at least one distal end through the hollow interior of the absorbent body, stitching the distal ends of the porous sheet together, and punching a string through the protective sleeve and absorbent body.

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.

Tampons including an elongate body and a removal string extending from a removal end of the elongate body. The tampons may include an absorbent material and a spiral flow path that directs menses across the elongate body. The spiral flow path includes at least one complete turn around the longitudinal axis of the elongate body.
