Embodiment Construction

[0077] figure 1 A device 1 according to the invention with a total of four processing cylinders 2 , 4 , 5 . 1 , 5 . 2 is shown schematically. Although the example is shown with four cartridges 2, 4, 5.1, 5.2, even a device with only two cartridges 2, 4 will still work. The processing cylinders 2 , 4 , 5 . 1 , 5 . 2 are arranged one behind the other and each carry out a processing step in forming a tampon.

[0078] The first processing cylinder 2 serves as a winding station. A strip-shaped material is introduced into the first processing drum 2 , which is then wound by the first processing drum 2 and wound into a first preform. For winding said strip-shaped material, the first processing drum 2 can be equipped with a set of forks which receive the strip-shaped material and wind the strip-shaped material into a coil by means of a rotational movement about its own longitudinal axis. As mentioned at the outset, the web material can be a laminate of non-woven fabric and cotton. ...

Abstract

The invention relates to a device for shaping tampons, comprising a plurality of machining drums 2, 4, 5.1, 5.2 for shaping a tampon made of web-like material. The device additionally comprises at least one transfer wheel 7 for continually transferring a preform from a first machining drum 2, 4, 5.1, 5.2 to a second machining drum 4, 5.1, 5.2. The invention also relates to a method for shaping a tampon made of web-like material, wherein a transfer from a first machining drum to a second machining drum is carried out by means of a continuously rotating transfer wheel.

Description

technical field [0001] The invention relates to a device for forming tampons from a strip material and to a method for forming tampons from a strip material, both according to the preambles of the characterizing claims. Background technique [0002] Tampons used for feminine hygiene, especially during menstruation, essentially consist of absorbent material, usually a viscose tampon, which is first rolled into a characteristic elongated shape and then squeezed and forming. The processing from the strip-shaped starting material to the finished tampon is carried out step by step in a clock-controlled production line. In a first step, a strip of material is first wound, wherein around said strip a retraction thread is placed and tied before winding. Subsequently, the coil is squeezed with pressure. By correspondingly designing the extrusion tool, defined structures, such as the usual longitudinal grooves, can be produced on the finished tampon. Additionally, in the usual man...
