  Vorrichtung zum Runden oder Verschmälern von auf einer Papiervorgarnmaschine hergestellten
Faserstreifen. 



   Die auf Papiervorgarnmaschinen hergestellten Faserstreifen werden in der Regel vor dem Aufwickeln auf Spulen oder Trommeln o. dgl. durch Nitschel-oder Würgelapparate gerundet oder verschmälert. Diese Nitschel-oder Würgelapparate bestehen im wesentlichen aus Gummihosen ; Kautschuk ist jedoch ein verhältnismässig kostspieliges Material und zurzeit schwer oder gar nicht erhältlich. Auch ein Ersatzmaterial für Kautschuk zu beschaffen, ist mit grossen Schwierigkeiten verbunden und genügt nicht den Anforderungen. Andrerseits bedingt aber die Durchführung einer wirtschaftlichen Arbeitsweise ein Vorbereiten der Papierstreifen vor dem Aufwickeln auf Spulen o. dgl. entweder durch Runden oder Zusammendrängen oder sonstiges Verschmälern der Streifen.

   Nach vorliegender Erfindung kommen an Stelle der bisher benutzten Nitschel-oder Würgelapparate Falzvorrichtungen in Anwendung, durch welche die auf der Maschine hergestellten Streifen hindurchgeleitet werden, um sie in der Längsrichtung zu falzen. Die Falzapparate können entweder so eingerichtet sein,   dass

   Es ist noch hervorzuheben, dass in der Papiergarnfabrikation die Verwendung von Falzvorrichtungen an sich bekannt ist, jedoch nur in Verbindung mit Streifen von bereits fertigem, in der Längsrichtung zerschnittenem Papier, Faserstoffstreifen, die frisch gebildet sind und daher noch in feuchtem oder halbfeuchtem Zustande sich befinden, zu falzen, ist bisher noch nicht in Vorschlag gebracht worden.

  Device for rounding or narrowing manufactured on a paper roving machine
Fiber strips.



   The fiber strips produced on paper roving machines are generally rounded or narrowed by Nitschel or dicing devices before being wound onto spools or drums or the like. These Nitschel or Würgelapparate essentially consist of rubber pants; However, rubber is a relatively expensive material and is currently difficult or impossible to obtain. Obtaining a replacement material for rubber is also associated with great difficulties and does not meet the requirements. On the other hand, however, the implementation of an economical way of working requires the paper strips to be prepared before they are wound onto bobbins or the like, either by rounding them up or by pressing them together or otherwise narrowing them.

   According to the present invention, instead of the previously used Nitschel or dicing devices, folding devices are used, through which the strips produced on the machine are passed in order to fold them in the longitudinal direction. The folders can either be set up so that
 EMI1.1
 



   The folding device shown for example in FIG. 1 is shown in FIGS. 2 and 3 on a larger scale. FIGS. 4 a to 4 g show sections of the folding device along the lines A-A, B-B, C-C, D-D, etc. in FIG. 3. The mode of operation of the folding devices can be easily understood from these figures.



   Instead of removing the paper strips from the distribution drum b, they can also be discharged at any other point in the machine, for example at the guide roller f.
 EMI1.2
 endless band d is performed.



   It should also be emphasized that in the manufacture of paper yarn the use of folding devices is known per se, but only in connection with strips of already finished paper cut in the longitudinal direction, fiber strips that are freshly formed and are therefore still in a moist or semi-moist state to fold has not yet been proposed.
