PCT No. PCT/EP90/00008 Sec. 371 Date Nov. 2, 1990 Sec. 102(e) Date Nov. 2, 1990 PCT Filed Jan. 3, 1990 PCT Pub. No. WO90/07314 PCT Pub. Date Jul. 12, 1990.The invention relates to a process and an apparatus for the continuous production of absorbent bodies (30) from a web of fiber 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 fiber 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 DEG relative to one another. By means of these press rollers, the web of fiber 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. |
