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 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.

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.

The current invention concerns an improved method for intermittently providing strips of a continuous first web material onto a continuous second web material, in particular a method for manufacturing tampon blanks, in a continuous process, thus avoiding the disadvantages of stop-and-go methods. Furthermore, an apparatus or system is provided for executing said methods.

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 absorbent for insertion into a vaginal cavity is provided. The tampon absorbent includes a longitudinal direction and has an insertion end and a withdrawal end. The tampon absorbent includes a first absorbent material portion at the insertion end for capturing body fluid and demonstrating a first expansion capacity, and a second absorbent material portion at the withdrawal end for storing body fluid and demonstrating a second expansion capacity. The second absorbent material portion is partially wrapped around the first absorbent material portion in a direction transverse (perpendicular) to the longitudinal direction, at a bonding region, whereby the first absorbent material portion is bonded to the second absorbent material portion at the bonding region.

A tampon for use in feminine hygiene. The tampon has an elongate body and a string. The elongate body has a first end, a second end, and an interior. The string has a first end, a second end, and an intermediate portion. The first end and the second end of the string are attached to the interior of the elongate body such that the first end and the second end are separated and the intermediate portion of the string forms a loop that extends from the second. end of the elongate body. The loop provides a grip to assist in removing the tampon.

A tampon produced by a method of multiple successive passes of a needle through a fiber web in a manner such that the tampon is afforded a desirable structural configuration and optimized characteristics, including tensile strength, relative absorbency, linear density, and thickness.

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.
