  Method and apparatus for producing a continuous cylindrical
Cotton tampon cord made from cotton wool
The invention relates to a method and a device for producing a continuous, cylindrical cotton tampon cord from cotton wool by means of a rolling device having parallel winding rollers.



   According to the method according to the invention, a wadding web is continuously fed from the card to the rolling device and in the latter by one to the feed ng- direction inclined, to the wat. teflorbahn plane parallel tam. ponaelLse wound. t, whereby the winding wanders out of the polling device in the direction of the axis.



   The device according to the invention for carrying out the method is equipped with a conveyor belt feeding the wadding web of the rolling device and is characterized in that a pair of rolls of the rolling device on the side of the belt carrying the web is parallel to the plane of the immediately adjacent part of the same, but is arranged obliquely to the supply direction of the tape.



   The subject matter of the invention is then explained on the basis of a. The exemplary embodiment shown on the drawing is explained in more detail.



     Fig. 1 shows the device in a perspective view.



   Fig. 2 shows a side view of the device.



   Fig. @ Is a basic principle of the device.



   The device consists of a rotatable position. rten guide rollers 1 and 2 running, mechanically driven, endless conveyor belt 3, onto which the single-layer wadding web, which is continuously combed by a pick roller 4 of the pile card by means of a cable 5, is transferred. Above the guide roller 2, which is close to the doffer roller 4, a pressure roller 6 is rotatable and adjustable in height, under which the wadding web lies on the conveyor belt and is smoothed by this and then pressed onto the conveyor belt.

   Depending on the desired thickness of the tampon cord to be produced, the wadding florbalin corresponding to the total card width of the doffing roller 4 can be divided over several belts, with this. only more or less material is processed per tampon string. In the present exemplary embodiment, three bands are provided, and the pile on the card is made with a conventional pile pile, not shown. The device is divided into three individual piles arranged next to one another so that three tampon cords can be rolled at the same time.

   Between the two guide rollers 1 and 2 is one of three rollers 7, 8 and. 9 existing rolling device is arranged in which the mutually parallel roller axes are parallel to the plane of the immediately adjacent part of the belt 3, but at an angle to the feed direction of the belt

Claims

PATENT CLAIMS I. Process for the production of a continuous cylindrical cotton tampon cord from wadding by means of a rolling device with parallel winding rollers, characterized by the fact that a web of wadding (10) is continuously fed from the card (4) to the rolling device (3, 7 to 9) and in the latter by a zu. guiding direction inclined tampon axis, parallel to the wading element orbit plane, is wound up, the winding (11) wandering out of the rolling device (3, 7-9) in the direction of the rolling device (3, 7-9).

II. Apparatus for performing the method according to claim I, with a watt. Eflorbahn the rolling device x leading conveyor belt, characterized in that a pair of winding rollers (7, 9) of the rolling device (3, 7-9) on the side of the belt (3) carrying the card web (10) parallel to the plane of the directly be - Adjacent part of the same, but obliquely xur feed direction. ung of the tape is arranged.

SUBMISSION 1. Vorriehtung naeh patent claim II, characterized in that opposite the winding roller pair (7, 9) on the side of the conveyor belt (3) facing away from this one of the latter supporting roller (8) axially parallel to the roller pair (7, 9) is arranged.

2. Vorriehtung naeh Unteransprueh 1, characterized in that the angle (a) of the axial direction of the rolling device (3, 7-9) to the feed direction of the batt web (10) adjustable. r is.

3. Device according to Unteranspmch 2, characterized in that there. of the pair of winding rollers (7, 9), the roller (9) closer to the card (4) can be adjusted transversely to its axis in order to be able to adjust the hardness of the tampon cord (11). lie. The roller 7 barely touching the belt 3 is driven by a drive, not shown in the drawing, against the direction of movement of the belt, so that the roller surface takes the wadding web 10 brought up with it. The roller 9 arranged next to the roller 7 does not touch the former and is approached in the same direction of rotation as this.

The roller 9 causes the pile ba to be rolled up. hn to a roll 11 in the space between the rollers 7 and 9 and the conveyor belt 3, which is supported at this winding point by the roller 8 arranged on its underside. By adjusting the roller 9 up or down, the diameter and the hardness of the lap 11 can be regulated.

As a result of the inclined position of the rocking rollers 7, 8, 9 in relation to the feed direction of the conveyor belt 3 and depending on the size of this position angle α, the roll 11 moves axially as a continuous cotton tampon cord more or less quickly out of the rolling device. In the case of the tampon cover emerging from the side of the roller device, the wadding is wound up in a helical manner, but this cannot be seen on the tampon surface due to the extremely small thickness of the web and the fibrous nature of the wadding.

The rollers 7, 8, 9 are expediently driven by toggle joint shafts. After the tampon cord has been produced, tampons of the desired length can be continuously cut from it. If relatively thick tampons are to be manufactured, only one winding device that extends over the entire width of the card is used and the entire width of the batt width is processed in a winding 11. All materials that can be processed on a card, such as cotton, wool, synthetic fibers, etc., can be rolled into tampon strips, from which tampons are then made, which are primarily used for hygienic and medical purposes.
