Abstract

A handle for sacks or bags with a flat bottom, preferably with a cross or block bottom, consists of two strips of material which, in their position of use, are bent in an L-shape in cross-section, of which the one limb in each case, lying approximately in one plane, is bonded to the bottom and the other limbs resting against one another are provided with the handle. In order to prevent the handle (17) being torn out, even under relatively heavy loading, said handle consists of a material strip which is folded in a U-shape and whose handle limbs are bonded to the limbs of the strips of material (6, 11) between the latter which rest against and are bonded to one another. <IMAGE>

Description

Die Erfindung betrifft einen Traggriff für Säcke oder Beutel mit flächigen Böden, vorzugsweise mit Kreuz- oder Klotzböden, bestehend aus zwei in ihrer Gebrauchsstellung im Querschnitt L-förmig abgebogenen Materialstreifen, von denen die einen etwa in einer Ebene liegenden Schenkel mit dem Boden verklebt und die anderen aneinanderliegenden Schenkel mit dem Traggriff versehen sind, sowie ein Verfahren und eine Vorrichtung zu dessen Herstellung.The invention relates to a carrying handle for sacks or bags with flat bottoms, preferably with cross or block bottoms, consisting of two material strips bent in an L-shaped cross-section in their position of use, of which one leg lying approximately in one plane is glued to the bottom and the other adjacent legs are provided with the handle, as well as a method and an apparatus for its production.

Ein derartiger Traggriff ist beispielsweise aus dem DE-GM 8115909 bekannt. Dieser bekannte Traggriff ist dadurch gebildet, daß die aufragenden, Rücken an Rücken liegenden Schenkel der L-förmigen Materialstreifen mit einer beide durchsetzenden länglichen Grifflochausstanzung versehen sind. Bei diesem bekannten Traggriff sind die Endbereiche der Grifflochausstanzungen beim Tragen erhöhten Beanspruchungen ausgesetzt, so daß ausgehend von diesen Endbereichen der Ausstanzungen sich Anrisse ausbilden können, die zu einem Ausriß der Traggriffe führen können.Such a handle is known for example from DE-GM 8115909. This known carrying handle is formed in that the upstanding, back-to-back legs of the L-shaped material strips are provided with an elongated finger hole punching out which penetrates both. In this known handle, the end regions of the punched hole punchings are subjected to increased stresses when worn, so that starting from these end regions of the punched holes, cracks can form which can lead to tearing of the carrying handles.

Aufgabe der Erfindung ist es daher, einen Traggriff der eingangs angegebenen Art zu schaffen, bei dem die Gefahr des Ausreißens auch bei größerer Belastung nicht besteht.The object of the invention is therefore to provide a carrying handle of the type specified at the outset, in which there is no risk of tearing out even under greater loads.

Erfindungsgemäß wird diese Aufgabe bei einem Traggriff der gattungsgemäßen Art dadurch gelöst, daß dieser aus einem U-förmig gefalteten Materialstreifen besteht, dessen Traggriffschenkel zwischen den aufeinanderliegenden und miteinander verklebten Schenkeln der Materialstreifen mit diesen verklebt sind.According to the invention, this object is achieved with a carrying handle of the generic type in that it consists of a U-shaped folded material strip, the carrying handle legs of which are glued to the material strips between the superimposed and glued legs of the material strips.

Bei dem erfindungsgemäßen Traggriff bilden somit die aufragenden und miteinander verklebten Schenkel der Materialstreifen, deren anderen Schenkel mit dem flächigen Boden verklebt sind, Halteteile für die Schenkel des U-förmigen Traggriffs, so daß die Schenkel auf Zug belastet werden und die Zugkräfte in einer Weise in die L-förmigen Materialstreifen eingeleitet werden können, daß sich keine einen Anriß bildende Spannungsspitzen ausbilden können.In the carrying handle according to the invention, the upstanding and glued legs of the material strips, the other legs of which are glued to the flat bottom, form holding parts for the legs of the U-shaped carrying handle, so that the legs are loaded in tension and the tensile forces in such a way the L-shaped strips of material can be introduced so that no stress peaks forming a crack can form.

Die Materialstreifen und/oder die Traggriffe bestehen zweckmäßigerweise aus Papier.The material strips and / or the carrying handles suitably consist of paper.

Ein Verfahren zur Herstellung der erfindungsgemäßen Traggriffe zeichnet sich erfindungsgemäß dadurch aus, daß ein einen Materialstreifen bildender Bahnabschnitt endseitig mit einem Leimauftrag versehen wird, daß auf diesen Leimauftrag ein um eine Querlinie gefalteter, den zweiten Materialstreifen bildender Bahnabschnitt, dessen umgefaltetes Teil mit den Traggriffschenkeln verklebt ist, aufgedrückt wird, und daß der freiliegende Teil des unteren Bahnabschnitts und der obere umgelegte, den Traggriff abdeckende Teil des oberen Abschnitts mit Leimaufträgen versehen werden und die so beleimte Einheit auf die Bodenfläche aufgedrückt wird.A method for producing the handles according to the invention is characterized in that a web section forming a strip of material is provided at the end with a glue application, that on this glue application a web section folded around a transverse line and forming the second material strip, the folded part of which is glued to the handle legs , is pressed, and that the exposed part of the lower track section and the upper folded part, covering the handle portion of the upper section, are provided with glue and the unit thus glued is pressed onto the floor surface.

Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens zeichnet sich erfindungsgemäß dadurch aus, daß ein mit Greifern versehener erster Greiferzylinder mit seinen Greifeinrichtungen das vordere Ende eines Bahnabschnitts erfaßt, daß an den ersten Greiferzylinder ein den Abschnitt mit einem streifenförmigen Leimauftrag versehender Zylinder eines Leimauftragswerks angestellt ist, daß an den ersten Greiferzylinder ein zweiter Greiferzylinder angestellt ist, der von einer Zuführungseinrichtung einen mit dem U-förmigen Griffteil verklebten Bahnabschnitt mit seiner Greifeinrichtung unter derartiger Faltung auf sich selbst übernimmt, daß der mit dem Griffteil verklebte Teil auf den nachlaufenden Teil des Abschnitts gefaltet wird, und der den mit dem Griffteil verklebten Teil auf den beleimten nachlaufenden Teil des Abschnitts aufdrückt, und daß an den ersten Greiferzylinder ein zweites Leimwerk angestellt ist, dessen Leimauftragswalze den vorauslaufenden Teil des ersten Abschnitts und den über den U-förmigen Griffteil gefalteten Teil des zweiten Abschnitts mit-Leimaufträge versieht, und daß der erste Greiferzylinder anschließend die Einheit auf den Boden aufdrückt.A device for performing the method according to the invention is characterized in that a first gripper cylinder provided with grippers grips the front end of a web section with its gripping devices, that a cylinder of a glue application unit is provided on the first gripper cylinder that provides the section with a strip-shaped glue application a second gripper cylinder is attached to the first gripper cylinder, which takes over a web section glued to the U-shaped grip part with its gripping device on itself from a feed device with such a gripping device that the part glued to the grip part is folded onto the trailing part of the section, and which presses the part glued to the handle part onto the glued trailing part of the section, and that a second gluing unit is employed on the first gripper cylinder, the glue application roller of which leads the leading part of the e The first section and the part of the second section folded over the U-shaped handle part are provided with glue applications, and that the first gripper cylinder then presses the unit onto the floor.

Verfahren und Vorrichtungen zur Herstellung von U-förmigen Griffteilen aus Materialstreifen sind beispielsweise aus den DE-PS 20 12 084 und 11 52 602 bekannt. Die Art der Herstellung U-förmiger Griffteile und die Art und Weise, wie diese auf einen diesen tragenden flachen Abschnitt aufgebracht werden, brauchen daher nicht näher beschrieben zu werden. Zu der Art der Herstellung und des Aufbringens U-förmiger Griffteile wird zusätzlich noch auf die DE-PS 20 18 081 und 11 81 035 verwiesen.Methods and devices for producing U-shaped handle parts from strips of material are known for example from DE-PS 20 12 084 and 11 52 602. The way in which U-shaped handle parts are produced and the way in which they are applied to a flat section carrying them need therefore not be described in more detail. Reference is also made to DE-PS 20 18 081 and 11 81 035 regarding the type of manufacture and application of U-shaped handle parts.

Ein Ausführungsbeispiel der Erfindung wird nachstehend an Hand der Zeichnung näher erläutert. In dieser zeigt

Aus Fig.1 ist schematisch eine Seitenansicht einer Vorrichtung zum Herstellen und Aufbringen von Traggriffen auf den flächigen Bodenteil von Beuteln oder Säcken ersichtlich, an Hand derer nunmehr die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren zur Herstellung der Traggriffe beschrieben wird. Die in die Vorrichtung hineinlaufende Papierbahn 1 wird von einer nicht dargestellten Vorratsrolle abgezogen. Der Abzug erfolgt durch das Vorzugswalzenpaar 2. Die in die Vorrichtung eingezogene Papierbahn 1 wird durch die rotierenden Perforiermesser der Perforierstation 3 in vorbestimmten Abständen mit querverlaufenden Perforierlinien versehen. Die perforierte Papierbahn 1 wird durch das Vorzugswalzenpaar zugleich auch festgehalten, so daß von der Papierbahn 1 durch den an den Greiferzylinder 4 angestellten Gegenzylinder einzelne Papierstreifen 6 längs der Perforationslinie gerissen werden, weil Umfangsgeschwindigkeit des Vorzugswalzenpaares 2 geringer ist als die Umfangsgeschwindigkeit des Greiferzylinders 4 sowie des an diesen angestellten Gegenzylinder 5. Auf dem Greiferzylinder 4 wird das vorauslaufende Ende des Streifen 6 durch in Nuten 22 angeordnete, nicht dargestellte Greifzangen festgehalten. Der auf dem Greiferzylinder 4 transportierte Streifen 6 wird dann von einer Leimauftragswalze eines Leimauftragswerks an seinem hinteren Bereich formatmäßig mit einem streifenförmigen Leimauftrag versehen.1 shows schematically a side view of a device for producing and applying carrying handles to the flat bottom part of bags or sacks, on the basis of which the device according to the invention and the method according to the invention for producing the carrying handles will now be described. The paper web 1 running into the device is drawn off from a supply roll, not shown. The pull-off takes place by means of the preferred pair of rollers 2. The paper web 1 drawn into the device is provided with transverse perforating lines at predetermined intervals by the rotating perforating knives of the perforating station 3. The perforated paper web 1 is held by the pair of preferred rollers at the same time, so that individual paper strips 6 are torn along the perforation line by the paper web 1 through the counter cylinder employed on the gripper cylinder 4 because the peripheral speed of the Preferred roller pair 2 is less than the circumferential speed of the gripper cylinder 4 and the counter cylinder 5 employed thereon. On the gripper cylinder 4, the leading end of the strip 6 is held by gripping pliers, not shown, arranged in grooves 22. The strip 6, which is transported on the gripper cylinder 4, is then provided with a strip-shaped glue application at its rear area by a glue application roller of a glue application unit.

Mit dem Greiferzylinder 4 wirkt ein zweiter Greiferzylinder 8 zusammen, der im Zusammenwirken mit einem Anpresszylinder 9 von einer ebenfalls perforierten Papierbahn 10 einzelne Streifen 11 abreißt. Die Bahn 10 wird in gleicher Weise wie die Bahn 1 von einem Vorzugswalzenpaar 12 von einer nicht dargestellten Vorratsrolle abgezogen, wobei in die Bahn 10 durch eine Perforierstation 13 in Abständen Querperforationslinien angebracht werden.A second gripper cylinder 8 interacts with the gripper cylinder 4 and, in cooperation with a pressure cylinder 9, tears off individual strips 11 from a likewise perforated paper web 10. The web 10 is drawn off in the same way as the web 1 by a pair of feed rollers 12 from a supply roll (not shown), with transverse perforation lines being provided at intervals in the web 10 by a perforating station 13.

Bevor von der Bahn 10 einzelne Streifen 11 abgerissen werden, gelangt die Bahn 10, geführt über einen Umlenkzylinder 14, in den Bereich eines Griff-Falt- und Auftragsaggregates 15, welcher aus den ihm zugeführten Griffstreifen 16 Henkelgriffe in bekannter Weise formt.Before individual strips 11 are torn off the web 10, the web 10, guided by a deflection cylinder 14, reaches the area of a handle-folding and application unit 15, which forms 16 handle handles in a known manner from the handle strips supplied to it.

Wegen der Art der Herstellung und des Aufbringen der U-förmigen Henkelgriffe wird auf die DE-PS 20 12 084, 11 52 602, 11 82 035 und 20 18 081 verwiesen.Because of the way of producing and applying the U-shaped handles, reference is made to DE-PS 20 12 084, 11 52 602, 11 82 035 and 20 18 081.

Die U-förmigen Henkelgriffe 17 werden in Abständen auf die Bahn 10 aufgebracht, sodaß jeder abgerissene Streifen 11 mit einem Henkelgriff versehen ist. Diese Henkelgriffe werden im Bereich der Umlenkwalze 14 auf die Bahn durch einen Hotmelt Auftrag aufgeklebt. Die Hotmelt-Einrichtung ist lediglich durch einen Pfeil 18 angedeutet worden.The U-shaped handles 17 are applied to the web 10 at intervals, so that each torn strip 11 is provided with a handle. These handles are glued to the web in the region of the deflection roller 14 by means of a hot melt application. The hot melt device has only been indicated by an arrow 18.

Der Anspresszylinder 9 ist mit einem nicht dargestellten schwertartigen Steg versehen, der den Streifen mit dem auf diesen aufgeklebten Henkelgriff unmittelbar hinter der Verklebung in die in einer Nut 20 angebrachten Haltezange hineindrückt, so daß dadurch eine Faltung bewirkt wird. Hinter dem Auslaufspalt der Zylinder 8,9 ist ein nicht dargestelltes Blech angeordnet, das den mit den Griffschenkeln verklebten Teil des Streifens 11 auf den nachlaufenden Teil in der aus den Fig.1 und 2 ersichtlichen Weise umfaltet, so daß die aufeinander gefalteten Teile durch die Zange 20 an ihrer Faltung gehalten sind.The pressure cylinder 9 is provided with a sword-like web, not shown, which presses the strip with the handle grip glued onto it directly behind the adhesive into the holding pliers arranged in a groove 20, so that folding is thereby effected. Behind the outlet gap of the cylinders 8, 9, a sheet metal (not shown) is arranged, which folds the part of the strip 11 which is glued to the grip legs onto the trailing part in the manner shown in FIGS. 1 and 2, so that the parts folded onto one another by the Pliers 20 are held at their fold.

Der in Figur 1 mit strichpunktierten Linien eingekreiste Teil ist in der Figur 2 vergrößert dargestellt. Aus dieser Figur ist zu erkennen, daß der vom Greiferzylinder 4 herantransportierte und an seinem Ende beleimte Streifen 6 mit den freien Schenkeln des Henkelgriffes 17 und mit der vorlaufenden umgeknickten Kante des Streifens 11 verklebt wird. Der Greiferzylinder 8 öffnet dann seine Zange 20, so daß das vorbereitete Griffstück 21 (Fig.3) nur noch von der Zange 22 des Greiferzylinders 5 transportiert wird. Das Griffstück selbst ist in der Figur 3 dargestellt.The part encircled with dash-dotted lines in FIG. 1 is shown enlarged in FIG. It can be seen from this figure that the strip 6 transported by the gripper cylinder 4 and glued at its end is glued to the free legs of the handle 17 and to the leading bent edge of the strip 11. The gripper cylinder 8 then opens its pliers 20 so that the prepared handle 21 (FIG. 3) is only transported by the pliers 22 of the gripper cylinder 5. The handle itself is shown in Figure 3.

Während des weiteren Verlaufes des Greiferzylinders 4 wird dann das Griffstück an ein Leimauftragswerk 19 vorbeigeführt, durch welches die gesamte dem Leimauftragswerk 19 zugewandte Oberfläche des Traggriffelementes 21 beleimt wird. Im Anschluß daran wird das Traggriffelement 21 auf den Boden 23 eines über den Zylinder 24 transportierten Beutels aufgeklebt. An seinem dem Traggriffelement 21 entgegengesetztem Ende ist der Beutel 25 noch offen, so daß er im Anschluß daran beispielsweise mit Windeln gefüllt werden kann, worauf dann das Einfüllende verschlossen wird.During the further course of the gripper cylinder 4, the grip piece is then guided past a glue application unit 19, through which the entire surface of the handle element 21 facing the glue application unit 19 is glued. Subsequently, the handle element 21 is glued to the bottom 23 of a bag transported via the cylinder 24. At its end opposite the handle element 21, the bag 25 is still open, so that it can then be filled with diapers, for example, after which the filling end is then closed.
