Description

       

  Verfahren und     Vorrichtung        zum    Beschichten eines durchlaufenden Metallbandes mit  Papierband     als        Zwischenlage    der nach dem Schnitt     zu    stapelnden     Blechtafeln       Die Erfindung bezieht sich auf eine Verbesserung  des Verfahrens und der Vorrichtung zum Beschichten  eines durchlaufenden Metallbandes mit Papierband  als Zwischenlage der nach dem Schnitt zu     stapelnden     Blechtafeln nach dem Hauptpatent.  



  Das Hauptpatent     betrifft    ein Verfahren zum Be  schichten eines durchlaufenden Metallbandes, insbe  sondere eines Messingbandes, mit Papierband, das  als Zwischenlage der nach dem Schnitt zu     stapelnden     Blechtafeln vorgesehen ist, welches sich dadurch  kennzeichnet, dass dem auf dem Metallband auflie  genden und mit diesem der Teilschere zugeführten  Papierband elektrische Ladungen zur Erzeugung von  elektrischen Feldern zwischen Papier und Metallband  aufgebracht werden, durch die das Papierband kurz  zeitig bis zu deren selbsttätigem Abbau auf dem  Metallband gehalten wird.  



  Es hat sich gezeigt, dass in Gebieten mit feuchtem  Klima, wie Küsten- und Tropengebieten, oder auch bei  Papierlagerungen in Kellerräumen infolge der Was  seraufnahme die Isolation des Papierbandes verrin  gert und damit der     Hafteffekt    herabgesetzt wird. Die  ser Nachteil wird nun durch die zusätzliche Erfin  dung vermieden, welche sich dadurch     kennzeichnet,     dass das     zugeführte    Papierband an einem Wärme  spender vorbeigeführt wird. Hierdurch wird erreicht,  dass das Papier zumindest während der kurzen Zeit,  während deren es auf das Blechband     aufläuft    sowie  mit diesem geschnitten und gestapelt wird, einwand  frei trocken ist und damit weitgehend isolierend  wirkt.  



  Im einzelnen können als Wärmespender Wärme  walzen dienen. Wobei die Wärme- und     Förderwalzen     vorteilhaft unmittelbar vor der Trennschere zum Ab  schneiden der Blechtafeln liegen.    In der Zeichnung ist beispielsweise eine Ausfüh  rungsform und Vorrichtung zur     Durchführung    des       Verfahrens    der Erfindung dargestellt, und zwar die  schematische Ansicht der Besprüheinrichtung nach  dem Hauptpatent für ein mit     einem    Papierband be  schichtetes Metallband zur kurzzeitigen Papierhaf  tung während und nach dem Schnitt zu     Blechtafeln     mit erfindungsgemäss vorgeschaltetem Wärmespen  der     in    Form von Wärmewalzen.  



  Wie aus der Zeichnung ersichtlich ist, wird das  Metallband z. B. Messingband 1 von einem Wickel  bund 2 entsprechend dem Hauptpatent abgezogen  und gelangt unter Zwischenschaltung von Zugwalzen  3 zu den Trennscheren 4, welche Blechtafeln 5 in der  gewünschten Grösse abschneiden. Vor dem Schnitt  wird dem Blechband 1 ein Papierband 6 von einem  Wickelbund 7 zugeführt und zwar unter Vorschaltung  von Wärmewalzen 3a und 3b zur Austrocknung des  Papiers. Die     Zugwalzen    3 fördern gleichzeitig das  Papier wobei die Oberwalze gummiert sein kann und  das Papierband 6 mit leichtem Druck auf das Metall  band 1 legt.

   Dieser Fördervorrichtung ist sodann die       Besprühvorrichtung    8 nach dem Hauptpatent nach  geschaltet, welche aus quer zum Blechband     im    Ab  stand angeordneten     Elektrodenspitzen    9 besteht, die  unter hoher Spannung, etwa 8000 bis 10 000 Volt bei  geringer Stromstärke, etwa 0,001     Amp.    elektrische  Felder erzeugen, welche das     Papierband    6 auf dem  Metallband 1 aufkleben, so dass beim Schnitt zu  Blechtafeln 5 mit Papierauflage 10 und anschliessen  dem Stapeln im Wagen 11 kurzzeitig eine feste     Haf-          tung,gewährleistet    ist.

   Nach etwa vier bis fünf Minu  ten sind die elektrischen Felder wieder abgebaut, so  dass das Papier 10 bei der Weiterverarbeitung der  Blechtafeln 5 ohne weiteres wieder abgenommen      werden kann. Der Schneid- und Stapelvorgang nimmt  nur wenige Sekunden in Anspruch, so dass die Kleb  zeit vollauf ausreicht, um die gewünschte Haftwir  kung zu erzeugen, wobei die vorherige Austrocknung  des Papiers dessen etwaigen störenden Feuchtigkeits  gehalt in jedem Falle verschwinden lässt. Wie aus  dem Hauptpatent weiter hervorgeht, besteht der     Be-          sprüher    8 aus einem unten offenen und langgestreck  ten Isolierstoffgehäuse 12, in welchem die Elektro  denspitzen 9 in Form von Nähnadeln kammartig  nebeneinanderliegend angeordnet sind.

   Dem elektri  schen Besprüher 8, 9 wird vom Stromnetz 13 mittels  Transformator 14 hochgespannter Wechselstrom von  etwa 8000 bis 10 000 Volt bei etwa 0,001 Amp. zu  geführt, welcher vermittels     zwischengeschaltetem     Stabgleichrichter 15 gleichgerichtet ist, wobei der  Anschluss sodann über einen Hochohmwiderstand  <B>16</B>     ,an.    die     Nadelspitzen    9 erfolgt.



  Method and device for coating a continuous metal strip with paper tape as an intermediate layer of the metal sheets to be stacked after the cut The invention relates to an improvement of the method and the device for coating a continuous metal strip with paper tape as the intermediate layer of the metal sheets to be stacked after the cut according to the main patent .



  The main patent relates to a method for coating a continuous metal strip, in particular a special brass strip, with paper tape that is provided as an intermediate layer of the metal sheets to be stacked after the cut, which is characterized in that the resting on the metal strip and with this the dividing scissors supplied paper tape electrical charges are applied to generate electrical fields between paper and metal tape, by means of which the paper tape is briefly held on the metal tape until it breaks down automatically.



  It has been shown that in areas with a humid climate, such as coastal and tropical areas, or when paper is stored in basement rooms, the insulation of the paper tape is reduced as a result of the water absorption, thus reducing the adhesive effect. This disadvantage is now avoided by the additional inven tion, which is characterized in that the fed paper tape is led past a heat donor. This ensures that the paper is perfectly dry, at least during the short time during which it runs onto the sheet metal strip and is cut and stacked with it, and thus has a largely insulating effect.



  In detail, heat can be used as a heat source. The heat and conveyor rollers are advantageously located immediately in front of the cutting shears for cutting off the metal sheets. In the drawing, for example, an Ausfüh approximate form and device for performing the method of the invention is shown, namely the schematic view of the spraying device according to the main patent for a metal strip coated with a paper tape for short-term paper adhesion during and after the cut to sheet metal with upstream according to the invention Heat spikes in the form of heat rollers.



  As can be seen from the drawing, the metal strip is z. B. pulled brass band 1 from a winding collar 2 according to the main patent and arrives with the interposition of pull rollers 3 to the cutting shears 4, which cut sheet metal 5 in the desired size. Before the cut, a paper strip 6 is fed to the sheet metal strip 1 from a winding collar 7, with heating rollers 3a and 3b connected upstream to dry out the paper. The pull rollers 3 simultaneously promote the paper, whereby the top roller can be rubberized and the paper tape 6 is applied to the metal tape 1 with light pressure.

   This conveyor is then the spraying device 8 according to the main patent, which was arranged across the sheet metal strip in the Ab electrode tips 9, which generate electrical fields under high voltage, about 8000 to 10,000 volts at low current, about 0.001 amp Glue the paper tape 6 onto the metal tape 1, so that when cutting into sheet metal 5 with paper overlay 10 and then stacking in the carriage 11, a firm adhesion is guaranteed for a short time.

   After about four to five minutes, the electric fields are broken down again, so that the paper 10 can easily be removed again during the further processing of the metal sheets 5. The cutting and stacking process only takes a few seconds, so that the adhesive time is completely sufficient to produce the desired adhesive effect, whereby the previous drying of the paper makes any disturbing moisture content disappear in any case. As can also be seen from the main patent, the sprayer 8 consists of an open at the bottom and elongated insulating material housing 12 in which the electrical denspitzen 9 in the form of sewing needles are arranged next to one another like a comb.

   The electrical sprayer 8, 9 is supplied with high-voltage alternating current of about 8,000 to 10,000 volts at about 0.001 amps from the power supply system 13 by means of transformer 14, which is rectified by means of an interposed rod rectifier 15, the connection then via a high-resistance <B> 16 </B>, on. the needle tips 9 takes place.
