METHOD FOR WINDING PREFORMS
20240189157 · 2024-06-13 · ·

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.

Tampon product including applicator having components molded of pulp-based composite

A tampon applicator assembly is disclosed. The applicator assembly may include a barrel portion, a grip portion and an ejection plunger configured to slide coaxially within one or both the barrel portion and the grip portion. One or more of the barrel portion, grip portion and ejection plunger may be molded from a molding composite comprising cellulose fibers.

Ready-to-use, hydrophilic, self-dispersive, fragmentable and biodegradable porous sponge matrix and a method of manufacturing thereof

The invention relates to porous absorbent Composite Material, which may be used e.g. in the form of a plug or tampon, for instance for controlling bleeding, wound closure, prevent tissue adhesion and/or support tissue regeneration. The invention provides a hydrophilic Self-Dispersive, fragmentable and Bio-Absorbable Porous Composite foams, suitable for packing antrum or other cavities of the body, comprising of composite of polymers, which polymer preferably comprises C(O)O; NH2/3+; OH; CH2OCH2C(O)O groups as functional or CHO (e.g. C2H4O; C6H10O5; C6H8O6); CHNO (e.g. C8H13NO5); OCC (e.g. OCH2-CH2); C(O)N groups in the backbone of the polymers e.g. gelatin, chitosan, collagen, alginate, polyvinyl alcohol, polyethylene glycol, keratin, cellulose.

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 AND APPARATUS FOR MANUFACTURING SHEET-LIKE MEMBER ASSOCIATED WITH ABSORBENT ARTICLE
20190125591 · 2019-05-02 ·

A method for manufacturing a sheet-like member, associated with an absorbent article, using a continuous sheet. The method includes a supplying step, a processing step, and a detecting step. In the supplying step, the continuous sheet is supplied by transferring the continuous sheet to a processing section by transporting the continuous sheet in a direction of transport. The processing step is performed at a predetermined position in the direction of transport, and a portion of the continuous sheet which is to be the absorbent article is processed by the processing section at an interval in the direction of transport. In the detecting step, a trace of the processing left on the continuous sheet is detected. In the supplying step, a direction-of-transport tension value of the continuous sheet at a time of transferring the continuous sheet to the processing section is adjusted based on the detection result.

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.

Methods and apparatuses for manufacturing multiple different articles are provided. One apparatus embodiment includes a first intravaginal article assembly module; a second intravaginal article assembly module; and an applicator module capable of receiving and handling applicators suitable for both first intravaginal articles from the first intravaginal article assembly module and second intravaginal articles from the second intravaginal article assembly module. The apparatus only operates with one of the first intravaginal article assembly module and the second intravaginal article assembly module at one time. The first intravaginal articles are absorbent articles and the second intravaginal articles are non-absorbent articles.

METHOD OF WINDING UP TAMPON MATERIAL

An improved apparatus for forming tampon blanks for further processing into compressed, self-sustaining tampons, permits increased speed and accuracy of the process step. The apparatus includes a sliver guide; a gripper capable of reciprocating motion and arranged and configured to cooperate with the sliver 5 guide to grasp an end of a sliver maintained therein; a winding mandrel; a plurality of winding cups; and e) a string application and knotter apparatus comprising a circular ring bearing having a string conveyor mounted thereon. The circular ring bearing of the string application and knotter apparatus defines a plane perpendicular to the sliver guide and motion of the gripper and parallel to the 10 winding axis of the winding mandrel.
