Tampon press
A press for shaping an absorbent tampon blank into a shaped tampon pledget includes a central cavity arranged and configured to accommodate an absorbent tampon blank having a front portion and a back portion. The main longitudinal axis of the press passes in the middle of the central cavity and a plurality of penetrating dies are arranged radially around the said main longitudinal axis. Each penetrating die has a pressing face on at least a fragment of its side facing the central cavity. The said press comprises at least one cam to actuate the plurality of penetrating dies. Furthermore, the plurality of penetrating dies comprises at least one penetrating die having a pressing face with a first shaped longitudinal profile, and least one penetrating die having a pressing face with a second shaped longitudinal profile.
TAMPONS COMPOSED OF AN INTEGRAL ABSORBENT MEMBER AND PROCESS FOR MAKING THE SAME
An absorbent tampon made of a compressed strip of needle punched fiber having a needle punch density of at least 5 punches per cm.sup.2. The strip has a minimum width of 30 mm and a minimum length of 100 mm and a minimum tensile strength of 10 N or greater.
METHOD OF MANUFACTURING A TAMPON
In the manufacture of a tampon, an absorbent structure composed of an absorbent material can be formed into a tampon blank. In various embodiments, a withdrawal element can be attached to the absorbent structure either before or after the absorbent structure is formed into a tampon blank. The tampon blank can then undergo a compression step which can result in the pledget of the tampon. The pledget, and resultant tampon, can have at least one linear channel and at least one non-linear channel.
ABSORBENT ARTICLE
The present invention prevents an absorbent body from twisting and splitting while maintaining the capability of fitting onto the buttocks of a wearer even when the absorbent body has a low fabric weight. The absorbent body (4) has a large number of compressed parts (20, 20, . . . ) formed in a region other than a region that extends in a widthwise center section along the longitudinal direction and includes portions corresponding to a body fluid excretion part (H) and the intergluteal cleft of the wearer. A region including a portion corresponding to the intergluteal cleft is an easily deformable region (21) without compressed parts (20). The easily deformable region (21) extends to an intermediate position in the longitudinal direction and does not reach the rear end of the absorbent body (4). The region extending behind the easily deformable region (21) to the rear end of the absorbent body (4) has compressed parts (20) formed thereon.
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.
APPARATUS FOR FORMING A CATAMENIAL TAMPON
A doming tool for manufacturing absorbent tampon includes a plurality of stations made of devices for shaping a tampon pledget tip, and a hollow mandrel engaging with the stations. The stations are supported by at least one mounting plate.
TAMPON PRESS
A press for shaping an absorbent tampon blank into a shaped tampon pledget includes a central cavity arranged and configured to accommodate an absorbent tampon blank having a front portion and a back portion. The main longitudinal axis of the press passes in the middle of the central cavity and a plurality of penetrating dies are arranged radially around the said main longitudinal axis. Each penetrating die has a pressing face on at least a fragment of its side facing the central cavity. The said press comprises at least one cam to actuate the plurality of penetrating dies. Furthermore, the plurality of penetrating dies comprises at least one penetrating die having a pressing face with a first shaped longitudinal profile, and least one penetrating die having a pressing face with a second shaped longitudinal profile.
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 PLEDGET WITH IMPROVED BY-PASS LEAKAGE PROTECTION
A tampon pledget is made by assembling one or more pads in a pad compression configuration, radially compressing the pad compression configuration in a traverse direction into a cylindrical form, and axially compressing the cylindrical form in a direction along a vertical axis to form the tampon pledget. In one embodiment, the axial compression is performed as a pressure is applied to at least one of a first and a second end of the cylindrical form. In one aspect of the present invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams and a density of about 0.4603 grams/cubic centimeter. In another aspect of the invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams and a density of about 0.4755 grams/cubic centimeter.
Method and apparatus for making tampons
The present disclosure relates to apparatuses and methods for making tampons including primary and secondary absorbent members. During assembly, primary absorbent members, a continuous length of secondary absorbent members, and a continuous cord are advanced in a machine direction. Leading edges of the primary absorbent members are separated from each other in the machine direction by a pitch distance. Discrete secondary absorbent members are cut from the continuous length of secondary absorbent members. Leading edges of the discrete secondary absorbent members are also separated from each other in the machine direction by the pitch distance. The continuous cord is positioned on the secondary absorbent members. And a secondary absorbent member is positioned in contact with a primary absorbent member. A thread is combined with the continuous cord, the secondary absorbent member, and the primary absorbent member.
