Description

Verfahren zum Herstellen formhaitiger Wattepreßlinge Die Erfindung bezieht sich auf ein Verfahren zum Herstellen formhaltiger Waterpreßlige und besteht darin, r1a13 die Formhaltikeit der Water durch Erwärmung während des preßvorganges erzielt wird. Bei Verwendung von Zellstoffwatte ist es zweckmäßig, diese nur bis etwa 952 ;- ( zu erwärnien, uni das Aussehen der Watte oder der Preßlinge durch Gelbfärbung und deren Saugfähigkeit nicht zu beeinträchtigen. Zur Erwärmung 1>enutzt man eille elektrische Heizeinerichtung, weil sich diese in der Preßvorrichtung licht unterbringen lält, Feuergefahr ausschließt und ein genaues Einregeln der Wärme ermöglicht. ii der Literatur i 1>ereits daraui liiii CVIescu or<Ieii. 1 ei <Ir Nerar1>einiig V( (11 Zellstoffwattc. Hitze anxuwenden, doch nur zu dem Zweck. eine Imprägniermasse leichter zu lösen. Es wurde aber daber weder erkannt and auch nicht offenbart, daß man die Wärme dazu ausnutzen kann. Watte auf trocknom Weg zu daucrnd formhaltige Körpern zusammenzupressen.Method of making form-retaining cotton compacts. The invention relates to a process for the production of form-retaining Waterpreßlige and consists therein, r1a13 the form retention of the water through heating during the pressing process is achieved. When using cellulose wadding, it is advisable to only use this up to about 952; - (to be heated, uni the appearance of the cotton wool or the pellets through Yellowing and not affecting their absorbency. Used for heating 1> an electrical heating device is required because it is illuminated in the pressing device can accommodate, eliminates the risk of fire and enables precise control of the heat. ii of the literature i 1> already daraui liiii CVIescu or <Ieii. 1 ei <Ir Nerar1> agree V ((11 cellulose watts. Apply heat, but only for the purpose of an impregnation compound easier to solve. But it was neither recognized nor revealed that the heat can be used for this purpose. Cotton to keep its shape permanently in a dry way Pressing bodies together.

Die erfindungsgemäßen Wattepreßlinge haben den Vorzug, unter entsprecher Ausdehnung große Mengen Flüssigke aufnehmen zu können. Durch ggeigl Formgebung können sie daher in Körl höhlen. z. B. in rlie weibliche Scheide. geführt werden. Wobei der weitere Vol l)esteht, daß die Formhaltigkeit ohne Zu: irgendwelcher bindemittedl erreicht wird. erfahrungsgemäß unter dem Eintluß Sckrcten sehr leicht zu Gärungen Ai: gel>en können. Die Preßlinge nehmen 1) Transport und bei der lagerung nur rin'en fQauni in knspruch. as 1 >eis.pi< weise für Kriegssanitätszwechke, für Klc kinderwindeleinlagen usm. von Vorteil Die Formhaltigkeit derartig 1 hergestel weattepreßlinge läßt sich zwar auch scl bei erheblich niedrigeren Temperaturen reichen. doch geht dies auf Kosten schnelligkeit in der massehnderstellung, v bei geringeren Temperaturn die Formlin 1 äliger iii der Preßform bleiben iuuss selbstverständlich bezicht sich l lie Fon haltigkei nicht Iiur auf tlic Ol Oberfläch gestaltung der Preßkörper, sondern auch : etwa eingepreßte Vertieiungen irgendweicher Art. Te nach Erfordernis kann die Watte ein-, iuehr- oder al r eit: geprebt werden. The cotton pellets according to the invention have the advantage of being corresponding Expansion to be able to absorb large amounts of liquid. Thanks to the design, you can therefore they cave in Körl. z. B. in rlie female vagina. be guided. Whereby The rest of the l) it is that the shape retention is without admission: any binding is achieved. Experience has shown that fermentations are very easy under the influence of sugar Ai: to be able to. The compacts take 1) transport and storage only rin'en fQauni in knspruch. as 1> eis.pi <wise for war ambulance exchanges, for Klc children's diaper liners, etc. Advantageous The dimensional stability in such a way 1 established Weattepreßlinge can also be reached at considerably lower temperatures. but this is at the expense of speed in mass production, v with lower ones The temperature of the mold in the 1 ½ age of the mold must of course remain does not deny itself the content of the oil on the surface design of the Pressed body, but also: any pressed-in recesses are somehow softer Art. Te as required, the wadding can be tested in, for the first time or for the first time.

Ebenso kann der auszuubende Druck lem jeweiligen Verwendungszweck cier Preßlinge angepaßt verclen. Das gleiche ist mit der Art und Anordnung ler Preßformen der Fall. so wird man für den Großbetrieb die Preßformen und Preßwerkzezeuge an den bekannten. rotierenden Tischen anorinen.The pressure to be exerted can also be used for the respective purpose Verclen cier pellets adapted. The same is with the type and arrangement of ler molds the case. so you will use the molds and pressing tools for large-scale operations the known. rotating tables anorines.

Auch können eckige Prebformen oder solche mit kreisrundem oder ovalem querscanitt Verwendung finden.Angular preforms or those with a circular or oval shape can also be used querscanitt use.
