Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung betrifft eine Falzvorrichtung für Briefumschlag-, Papierdüten-, -Sack- und dergl. Maschinen, deren Neuheit in der Anordnung von Hülfsklappen besteht, die den vom Oberstempel in den Falzkasten eingebrachten Bogen direct an den Kanten erfassen und scharf und gleichmäfsig umbiegen. Das vollständige Umlegen erfolgt dann von den Hauptklappen.The present invention relates to a folding device for envelopes, paper bags, -Sack and the like. Machines whose novelty consists in the arrangement of auxiliary flaps, the grasp the sheet brought into the folder box by the upper punch directly at the edges and bend sharply and evenly. The complete transfer is then carried out by the Main flaps.

Auf der beiliegenden Zeichnung istOn the accompanying drawing is

Fig. ι ein Querschnitt,Fig. Ι a cross section,

Fig. 2 eine Draufsicht der Falzvorrichtung.Fig. 2 is a plan view of the folding device.

Der Falzkasten α bekannter Bauart ist mit Ansätzen b für die Achsen c versehen, auf welchen die Triebhebel d festgemacht sind. Die Hauptklappen r sitzen auf den Achsen c, durch welche sie ihre Bewegung erhalten. Unterhalb der Achsen c sind Spindeln f in den Lagern 0 drehbar angebracht. Die Spindeln f tragen die Hülfsklappen g, welche mit einer schmalen Falzkante h ausgerüstet sind. Die Hülfsklappen g erfordern nur eine geringe Bewegung, die auf verschiedene Weise bewirkt werden kann. In vorliegendem Beispiel erfolgt die Bewegung folgendermafsen:The folding box α of known design is provided with lugs b for the axes c , on which the drive levers d are fixed. The main flaps r sit on the axes c, through which they receive their movement. Below the axes c , spindles f are rotatably mounted in the bearings 0. The spindles f carry the auxiliary flaps g, which are equipped with a narrow folded edge h . The auxiliary flaps g require only a slight movement, which can be effected in various ways. In this example, the movement takes place as follows:

Mit den Spindeln f ist je ein Stab i verbunden, der durch eine Schraubenfeder k nach unten gezogen wird, wodurch die wirksamen Kanten h von dem Unterstempel / abgehoben werden. Auf den Unterstempel werden sie gedrückt durch unrunde Scheiben m, die auf den Achsen e befestigt sind, und zwar derart, dafs beim Heruntergehen der Hauptklappen (linke Seite Fig. 1) die Scheiben m in Wirkung treten und die Hülfsklappen g nach abwärts bewegen. Durch die Gestaltung, die man diesen Scheiben m geben kann, sowie durch Verstellung derselben hat man es in der Hand, die relative Bewegung der beiden Klappensysteme zu regeln. Beim Aufgehen der Hauptklappen r treten die Hülfsklappen g selbstthätig durch den Einflufs der Federn k zurück.A rod i is connected to each of the spindles f and is pulled downwards by a helical spring k , as a result of which the effective edges h are lifted off the lower punch /. They are pressed onto the lower punch by non-circular disks m, which are attached to the axes e , in such a way that when the main flaps go down (left side Fig. 1) the disks m come into effect and move the auxiliary flaps g downwards. Through the design that can be given to these disks m , as well as by adjusting the same, it is in the hand to regulate the relative movement of the two flap systems. When the main flaps r open, the auxiliary flaps g automatically retract under the influence of the springs k .

Zwecks. Verminderung der Reibung können die Scheiben m mit Druckröllchen versehen werden.For the purpose of. Reduction of friction, the discs m with pressure rolls are provided.

Durch die Anordnung der Hülfsklappen erzielt man einen sauber und scharf gefalzten Briefumschlag, Papierbeutel, Düte oder Sack u. s. w.The arrangement of the auxiliary flaps results in a clean and sharp fold Envelopes, paper bags, cones or sacks and so on.

Claims (1)

Patent-Anspruch:Patent claim: Eine Falzvorrichtung für Briefumschlag-, Papierdüten-, -Sack- und dergl. Maschinen, dadurch gekennzeichnet, dafs unterhalb der bekannten Falzklappen (r) Hülfsklappen (g) mit nasenartigen Ansätzen (h) derart drehbar angeordnet sind, dafs die Klappen (r) bei ihrem Niedergang die Hülfsklappen (g) unter Vermittelung von Excentern oder dergl. gegen den zu falzenden Umschlag bewegen, so dafs die Nasen (h) die Kanten des Umschlags vorfalzen. A folding device for envelope, paper bag, sack and similar machines, characterized in that auxiliary flaps (g) with nose-like extensions (h) are rotatably arranged below the known folding flaps (r ) in such a way that the flaps (r) are at As they go down, move the auxiliary flaps (g) against the envelope to be folded using eccentrics or the like, so that the lugs (h) pre-fold the edges of the envelope.
