System and method for tearing off and rolling up a strip of absorbent fiber sheet
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.
Tampon and method for making the same
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.
METHOD FOR PRODUCING A TAMPON
A tampon (1) has 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 device (5) connected to the absorbent body and situated at the distal end (3). The tampon has a covering made from a nonwoven material (4), which, with the exception of a pass-through opening (13) for the extraction device (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.

Tampon with consolidated fibrous assembly and method of making
The present disclosure describes a tampon article, a composite fibrous web, and a method of making same. Such an article includes an outer carrier component including an inner surface that defines an internal void. Including an absorbent component elongate along an axis and is disposed in the internal void. The absorbent component includes an outer surface that extends about the axis and faces the inner surface. The absorbent component further includes a composite fibrous web of staple cellulosic fibers and a meltspun web of filaments entangled with the web of staple cellulosic fibers. The composite fibrous web can be in a compressed configuration in the internal void such that at least portion of the outer surface of the absorbent component is defined by the meltspun web of filaments. The tampon can include a withdrawal cord coupled to the absorbent component.
TAMPONS AND METHODS FOR MAKING TAMPONS
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.
Tampon
A tampon, particularly for feminine hygiene, comprises a substantially cylindrical absorbent body that is peripherally compressed and contained in a wrapper or in an applicator device. The absorbent body is formed by a rolled rectangular strip of absorbent material and comprises: a front end in the direction of insertion of the tampon, a rear end from which extends a removal string, and a lateral surface. The entirety of the outer surface of the absorbent body, corresponding to the front end, rear end and lateral surface is formed by a first layer of non-woven absorbent fabric.
Tampons made of non-woven fabric
Tampons and production methods are provided that provide tampons made of at least 80% cellulose-based fibers, such as cotton or viscose, without plastic top sheets. The tampons consist of cylindrically-compressed rolled strips of entangled non-woven fabric and may be made of 100% natural cellulose-based fibers, the fabric having a tensile strength that is larger than 10N/50 mm. The fabric may be folded longitudinally in various folding configurations and rolled transversely before compression to tampon dimensions.

METHOD FOR WINDING PREFORMS
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.
