"Tampon for feminine hygiene"

The invention relates to a tampon for feminine hygiene, which consists of a tampon provided with a withdrawal thread and subsequently wound and pressed fiber fleece, e.g. a wadding fleece.

A known tampon of this type (according to DT-OS 1 491 162) has a return thread, which grips around the two narrow sides of the fiber fleece in approximately the middle of the winding process and which forms a loop by knotting its ends protruding beyond a side edge of the fleece. This knotting the Thread ends had become absolutely necessary, after which experience with tampons with untied thread ends showed that a The thread grasped at only one end then inevitably with its other end from which the liquid has been absorbed and thus swollen Tampon rushed out. The production of such a tampon not only requires a complicated and trouble-free one

Knotter device, but is also only intermittent Operation possible.

Another known tampon of the aforementioned type (according to DT-OS 2 409 218) should be provided with a withdrawal thread be that this by means of a hollow needle guided to the longitudinal axis of the fleece through several wave-shaped elevations of a Fleece part punched through the hxnderich and clamped during the return stroke of the needle in the pierced fleece part and then with this was rolled up. The production of this tampon also only allowed intermittent operation and has grown not proven in practice.

The present invention has for its object to be a To create a tampon of the type mentioned at the beginning, whose retrieval thread without piercing, knots and similar aids, is to be arranged on a wadding so that on the one hand one a secure thread fit is guaranteed and, on the other hand, a continuous production operation is ensured.

According to the invention, this object is achieved in that the withdrawal thread arranged with one part of its entire length parallel to the longitudinal direction of the fiber fleece on this and together is to be wound and pressed with it, while another part of the return thread r, atwa, is perpendicular to the longitudinal axis of the

Fiber fleece is bent over its thin longitudinal edge. In this way, a tampon is created, the withdrawal thread part of which also cannot rush out of the swollen fleece part and its fleece part beyond that through the spirally wrapped one Part of the thread experiences a constriction when pulling the protruding thread part, which makes it easier to remove.

According to an advantageous feature of the invention, the withdrawal thread is located approximately in the middle of the fiber fleece, the latter being wound up from the end on which what is left on it Part of the thread lies. It is also possible to loosen the retrieval thread before the winding process without fasteners to be arranged between two wadding fleeces of equal length and width as well as parallel to each other.

Two exemplary embodiments of the invention are described below with reference to the drawings.

In FIGS. 1 to 3, a return thread 2 is arranged centrally on a fiber fleece 1. The return thread 2 runs with its largest thread part 2 'approximately parallel to the side edges of the fiber fleece 1. In the vicinity of the end 1 ″ of the fiber fleece 1, the return thread 2 with its part 2 ″ is ^{bent approximately at right angles to the part 2 1} and protrudes with its Extending end 2 ¹ ″ beyond one of the side edges I ^{1 of} the fiber fleece 1. The fiber fleece is wound up in the direction of arrow B from the fleece ^{end I 1 ″.} In principle, winding in the direction of arrow A is also possible, with the bent thread part 2 ', 2 ^IM then advantageously assuming the position shown in phantom in FIG

In Fig. 4, the return thread parts 2 ¹ , 2 ″ are loosely arranged before the winding process without fastening means between two wadding fleeces 1, 11 of equal length, width and parallel to each other. Corresponding parts of FIGS. 1 to 3 are shown in FIGS Here, too, the winding process begins in each case at the fleece end 1 " ^{1 facing away from the unwound thread end 2 1} , 2", the winding device in the direction of arrow B as

Fig. 5 shows the double-layer fleece 1, 11 in an almost wound up Manufacturing phase, while FIG. 6 shows the finished tampon blank 3, at the end point 2 of which the pull-out end 2 '"of the Return thread 2 protrudes.

It goes without saying that various modifications are possible within the scope of the invention. For example, it is possible to make the return thread 2 as long as the length of the fleece 1 or and to bend it at right angles ^{in the middle with its thread parts 2 ″ and 2 1 ″.} Nevertheless, this arrangement is not so advantageous compared to the arrangement shown with a return thread part 2 'arranged almost over the entire length of the fleece 1 or 11 because of the reduced length of the wound thread and the reduced frictional forces.
