<p>The invention relates to a process and an apparatus for the contiunuous production of absorbent bodies (30) from a web of fibre material (40) which is folded longitudinally several times in a folding station (A) and which is surrounded in a guide tube (86) with a sheathing band (82), the longitudinal edges of which are connected to one another by means of a closing device. The web of fibre material (30) is thereafter fed to a press station (C) which consists of pairs of press and smoothing rollers arranged in close succession and offset at 90° relative to one another. By means of these press rollers, the web of fibre material (130) is rolled down in steps to or below the final cross-section of the absorbent body (30), to form a fleece rod (240). Subsequently, the absorbent bodies (30) are pinched by means of pinching rollers (334, 338) in a severing station (D) and are thereby preformed at the front end and thereafter fed to a forming device, by means of which the front ends of the absorbent bodies (30) are equipped with a round dome and the rear ends of the absorbent bodies (30) with a depression as an insertion aid, when the absorbent body (30) is to be used as a tampon for feminine hygiene. The process and the apparatus allow the high-speed mass production of absorbent bodies which, whilst using less material, make it possible to achieve a higher stability or buckling resistance of the absorbent bodies.</p> |
