PATENTAMT.PATENT OFFICE.
Das Aufwickeln von in Falten gelegten Papier-, Stoff- und ähnlichen Bahnen bereitet insofern Schwierigkeiten, als die dabei erforderliche Spannung die Falten auseinanderzieht. Um dies zu verhindern, wird nach der Erfindung ein Schutzstreifen mit aufgewickelt, der sich bei Anwendung von' Druck mit der Faltenbahn zugleich aufrollt. Dieser Druck, erzeugt durch eine federnde Rolle aus GummiThe winding of folded paper, fabric and similar webs prepares difficulties in that the tension required thereby pulls the folds apart. To prevent this, a protective strip is wound with the invention when applying pressure, it rolls up with the fold sheet at the same time. This pressure, creates by a resilient roller made of rubber
ίο oder durch eine ähnliche Einrichtung, muß dort einsetzen, wo die Falte in die Einklemmung eintritt, denn im Augenblick dieser Einklemmung beginnt zugleich das Aufrollen und somit die Spannung.ίο or by a similar body, must insert where the fold enters the entrapment, because at the moment this Entrapment begins at the same time as the roll-up and thus the tension.
!5 Bei der Einrichtung nach Fig. ι läuft der von der Rolle α kommende Schutzstreifen über eine Rolle c auf eine Schiene s und wird auf die Rolle b aufgerollt. Die in Falten gelegte Bahn P gelangt oberhalb der Rolle c auf den Schutzstreifen, geht mit ihm über die Schiene s und tritt mit ihm an der Stelle k in die Klemmung zwischen Aufwickelrolle b und Gegenrolle w. Der Druck der federnden Rolle w drückt die Falte fest, und die weitere Drehung der Rolle w hat zur Folge, daß die Falte unterhalb des jetzt noch mehr gespannten Schutzstreifens niedergedrückt bleibt.In the device according to FIG. 1, the protective strip coming from the roll α runs over a roll c onto a rail s and is rolled up onto the roll b. The creased web P arrives above the roll c on the protective strip, goes with it over the rail s and enters with it at the point k in the clamping between the winding roll b and the counter roll w. The pressure of the resilient roll w presses the fold firmly , and the further rotation of the roller w has the consequence that the fold remains depressed below the now even more tensioned protective strip.
Nach Fig. 2 ist der Einklemmungspunkt der Falten von der Rolle b fort verlegt an eine andere Stelle k. Die Spannung, welche nach Fig. 1 die Rolle b übernimmt, tritt hier schon vorher ein, und zwar auf der konvexen Seite einer gebogenen Schiene s, auf welcher auch der von der Rolle α kommende Schutzstreifen läuft. Die Faltenbahn P tritt an der Stelle k zwischen den über die Rolle c laufenden Schutzstreifen und die konvexe Seite der Schiene s. Auch hier kann eine Feder oder federnde Rolle w im Augenblick der Einklemmung der Falte einen Druck ausüben. Die Schiene s kann innen glatt sein, damit jede Faltendehnung ausgeschlossen ist. Den federnden Druck auf die Falten kann auch eine zweite auf die konvexe Schiene passende konkave Schiene übernehmen.According to FIG. 2, the pinch point of the folds is moved away from the roll b to another point k. The tension, which takes over the role b according to FIG. 1, occurs here already beforehand, namely on the convex side of a curved rail s on which the protective strip coming from the role α also runs. The fold path P occurs at the point k between the protective strip running over the roller c and the convex side of the rail s. Here, too, a spring or resilient roller w can exert a pressure at the moment the fold is pinched. The rail s can be smooth on the inside so that any stretching of the folds is excluded. The resilient pressure on the folds can also be taken over by a second concave rail that fits onto the convex rail.
