  Einrichtung zum Falzen von Papierbändern. 



   Die Erfindung betrifft eine Einrichtung zum Falzen von Papierbändern, die aus Krepp- od. dgl. 



  Papier bestehend, als Binden für Verbandszwecke verwendet werden und zur Erzielung einer besonderen Festigkeit gegen Zerreissen dreifach, u. zw. an beiden Rändern und in der Längsmitte gefalzt sind. 



   Gemäss der Erfindung be itzt die Einrichtung für die Herstellung der Randfalze, flanschartig ineinandergreifende und in die Bandränder umbiegende   Walzenp. iare,   hinter welchen sich Falzumlegleisten befinden. sowie zur Herstellung   de ? mittleren Falze ?   zwei oder mehrere rinnenförmig ineinandergreifende Walzenpaare mit einer hinter dierer befindlichen Druckleiste zum Umlegen des von diesen Walzenpaaren durchgedrückten   Bandgrate3.   



   In der Zeichnung ist eine Ausführungsform eine solchen Einrichtung in Fig. 1 im   Längsschnitt   und in Fig. 2 in Draufsicht unter Hinweglassung aller   Nebenteile dargestellt.   Fig. 3 ze gt im vergrösserten Massstab den Querschnitt des fertig gefalzten Bandes und Fig. 4 und 5 zeigen Einzelteile. 



   Die Einrichtung besitzt an der Einlaufseite des Papierstreifens b zwei oder mehrere hintereinander liegende Walzenpaare   a, al (s.   insbesondere Fig. 4) deren obere Walzen a glatt gehalten und deren untere Walzen a1 durch Randflanschen q spulenförmig ausgestaltet sind. 



   Hinter diesen Vorfaltwalzen sind weitere, z. B. zwei Walzenpaare d, d1 (Fig. 5) vorgesehen, deren 
 EMI1.1 
   umschliessenden     Metallfassungen   bestehen, deren oberer Streifen an der Einlaufseite aufgebogen ist. 



  An gee'gneter Stelle sind Presswalzen c vorgesehen. 



   Die   Wirkungsweise   der Einrichtung ist folgende : Das von einer Vorratsrolle in der Pfeilrichtung Ablaufende Band b gelangt zwischen das erste ineinandergre fende Walzenpaar a, a1. durch welches die beiden Ränder der Bandes aufgebogen und gefaltet werden. Die erste Falzführung e nimmt die bereits aufgebogenen Ränder des Bandes b auf und legt sie um bzw. falzt sie vor, worauf der   Randfalz   durch das Walzenpaar c gepresst wird. Durch das nächste   Welhenpaar  . al   nebst einer weiteren Falzführung e wird der Falz verdoppelt und kann gegebenenfalls   verdure'fact   werden.

   Das   nunmehr   angreifende. gleichzeitig zum Pressen de   ? Doppelfalzes   dienende Walzenpaar d, d1 drückt das Band b in der Mitte mittels des Bundes i in der Längsmitte   grataitig   durch. Das folgende Walzenpaar d,   du   verstärkt den Bandgrat bl und spitzt ihn zu, der schliesslich mittels der Druckleiste f zum Falz umgelegt wird. Nach mehrmaligem Pressen wird das nunmehr mit drei Falzen versehene Band aufgerollt.

  Device for folding paper tapes.



   The invention relates to a device for folding paper tapes made of crepe or the like.



  Consisting of paper, used as a bandage for bandages and threefold to achieve a special strength against tearing, u. between both edges and in the longitudinal center are folded.



   According to the invention, the device for the production of the edge folds be itzt, flange-like interlocking rollers that bend into the band edges. iare, behind which there are folding strips. as well as for producing de? middle folds? two or more groove-like interlocking roller pairs with a pressure bar located behind them for turning over the belt burrs pressed through by these roller pairs3.



   In the drawing, an embodiment of such a device is shown in Fig. 1 in longitudinal section and in Fig. 2 in plan view with omission of all secondary parts. 3 shows, on an enlarged scale, the cross-section of the finished folded strip and FIGS. 4 and 5 show individual parts.



   On the inlet side of the paper strip b, the device has two or more pairs of rollers a, al (see in particular FIG. 4) whose upper rollers a are kept smooth and whose lower rollers a1 are designed in the shape of a coil by edge flanges q.



   Behind these pre-folding rollers are further, z. B. two pairs of rollers d, d1 (Fig. 5) are provided whose
 EMI1.1
   encircling metal frames, the upper strip of which is bent up on the inlet side.



  Press rollers c are provided at a suitable point.



   The operation of the device is as follows: The tape b running off from a supply roll in the direction of the arrow passes between the first interlocking pair of rollers a, a1. through which the two edges of the tape are bent and folded. The first folding guide e picks up the already bent-up edges of the band b and folds them over or folds them in front of them, whereupon the edge fold is pressed by the pair of rollers c. By the next pair of puppies. In addition to a further fold guide e, the fold is doubled and can optionally be reduced in size.

   The now attacking. at the same time as pressing de? The double fold serving roller pair d, d1 presses the belt b in the middle by means of the collar i in the longitudinal center in a straight-through manner. The following pair of rollers d, you reinforce the belt ridge bl and sharpen it, which is finally folded over to the fold by means of the pressure bar f. After pressing it several times, the band, which is now provided with three folds, is rolled up.
