Vorrichtung zur Herstellung von Platten aus streifenförmigem Material, z. B. elektrischem Isoliermaterial.Device for the production of panels from strip-shaped material, z. B. electrical insulating material.

Patentiert im Deutschen Reiche vom 11. Juli 1905 ab.Patented in the German Empire on July 11, 1905.

. Zur· Anfertigung von . Formstücken aus dünnen Platten beliebigen Materials, z. B. Papier, Glimmerplättchen usw., werden häufig schmale Streifen dieser Materialien schuppenartig in einer Lage oder in mehreren übereinander gelegt, um durch Pressen in einer Form oder auf andere Weise unter Verwendung eines geeigneten Binde- oder Klebmittels in die gewünschte Gestalt gebracht zu. For the production of. Fittings from thin plates of any material, e.g. B. paper, mica flakes, etc., are common narrow strips of these materials like scales in one layer or in several on top of each other placed to use by pressing in a mold or otherwise a suitable binder or adhesive brought into the desired shape

ίο werden. Solche Formstücke werden in der Elektrotechnik vielfach als Isolationsmaterial verwendet. Die .mit der Schneidvorrichtung hergestellten Streifen werden ihrer ganzen Länge nach und mit einem Teil ihrer Breite übereinander gelegt, so daß der folgende den vorhergehenden Streifen teilweise .überdeckt. Auf diese Weise kommt die schuppenartige Übereinanderlagerung zustande. Dabei können die einzelnen Streifen noch so übereinander gelegt werden, daß man durch die Art ihrer Aneinanderreihung ein langes Band erhält, oder aber durch Anordnung in einem Kreis eine flache Scheibe. Es ist unwesentlich, daß die Anordnung der einzelnen Streifen in einer Ebene erfolgt; die weiter unten beschriebene Vorrichtung kann ebensogut zum Legen von Streifen auf der Oberfläche eines Prismas, Zylinders, Kegels oder einer Pyramide verwendet werden. Bisher erfolgte das Zusammenlegen von Streifen ausschließlich von Hand, wobei eine Hauptschwierigkeit die Erzielung einer großen Gleichmäßigkeit war. Ungleichmäßigkeit beim Zusammenlegen liefert Formstücke von ungleicher Wandstärke, was häufig als großer Nachteil empfunden wird.ίο be. Such fittings are in the Electrical engineering is widely used as an insulation material. The .with the cutting device produced strips are along their entire length and with part of their width placed one on top of the other so that the following strip partially covers the previous strip. This is how the scale-like superimposition comes about. Here you can the individual strips can be laid on top of one another in such a way that one can see through the nature of their Lining up a long band, or by arranging them in a circle a flat disc. It is immaterial that the arrangement of the individual strips in one level takes place; the device described below can just as well for Laying strips on the surface of a prism, cylinder, cone or pyramid be used. Up until now, strips were only put together by hand, the main difficulty being the achievement of great evenness was. Unevenness when folding results in fittings with unequal wall thicknesses, which is often a major disadvantage is felt.

Die in der Zeichnung dargestellte Vorrichtung besteht aus der Kombination einer Tafelschere mit einer drehbaren Scheibe, welche letztere durch Bewegung des Schermessers in gleichmäßigen Abständen gedreht wird, so daß sich die auf der Schere geschnittenen Streifen einfach durch Herabfallen in oben beschriebener Weise schuppenförmig zu einer Scheibe, anordnen.The device shown in the drawing consists of a combination of one Guillotine shears with a rotating disc, which the latter by moving the cutter is rotated at regular intervals so that the cut on the scissors Simply arrange the strips in the manner described above in the manner of a slice by falling down to form a disk.

Das Tafelbett b der Schere ist auf einer Grundplatte α angeordnet und trägt in einem Lager drehbar den Hebelarm c mit Schneidmesser e. Das Gegenmesser/ ist ebenfalls mit b verschraubt. Die Scheibe d ist um einen Bolzen drehbar auf α gelagert. Die Vorrichtung zum Vorschub der Scheibe d besteht aus den Hebeln g der gezahnten Scheibe i, den Rollen k und den Schnurtrieben /. Bei Auf- und Abbewegung des Hebelmessers bewegen sich die Verbindungsstangen g hin und her, und zwar greift beim Hinaufbewegen des Hebels eine mit g in Verbindung stehende Schaltklinke in das gezahnte Rad i und nimmt dieses mit, während beim Herabdrücken des Hebels c die Scheibe i in Ruhe bleibt und die Schaltklinke, ohne zu greifen, zurückläuft. Da eine solche Vorrichtung vielfach verwendet wird, bedarf sie nicht der genaueren Beschreibung.The table bed b of the scissors is arranged on a base plate α and rotatably supports the lever arm c with cutting knife e in a bearing. The counter knife / is also screwed to b. The disk d is rotatably mounted on α about a bolt. The device for advancing the disk d consists of the levers g of the toothed disk i, the rollers k and the cord drives /. With up and down movement of the lever blade, the connecting rods move g back and forth, and that the lever engages in the ascent of a G related pawl into the toothed wheel i and takes this with, while c when depressed the lever, the slice i in Calm remains and the pawl moves back without grasping. Since such a device is widely used, it does not need to be described in more detail.

Mit der Scheibe i dreht sich die Welle,The shaft rotates with the disk i,

Claims

on which it is attached, and one of the two rollers k can also be firmly connected to the shaft by means of a suitable coupling. Of the cord drives I leading over the rollers k and the disk d, one is crossed, the other is open. Depending on whether one or the other role k is firmly connected to the toothed disk i , the disk d

ίο rotated in one direction or the other. The size of the advance of the disc d each time can be changed by adjusting the pivot point / z on the linkage g . The stops η and m (which are only drawn in the plan for the sake of clarity) are used to set the width of the strips to be cut, and since η can be rotated to m , as can be seen from the drawing, the strips to be cut can either be of the length to be cut evenly wide or unevenly wide. By adjusting the rail 0 screwed onto the plate b , which serves as a support for the material to be cut, the strips can be arranged in larger or smaller circles as desired.

The process is now as follows: The material to be cut is placed on the plate b at the system 0 and pushed so far between the shear blades that it strikes against the stop η. By moving the lever c down , a strip ■ is cut off and falls onto the disk d, the knife e still pressing down on it. By moving the cutting blade up, the above-described connection rotates the disc d a little, the material to be cut is pushed back against the stop η and a second strip is cut off by moving the lever c down and placed on the disc. This process is repeated as often as required until the desired number of strips is in one or more layers on the plate d .

If you want to layer a layer of the strips on top of each other in a different direction than the previous one, you only need to change the direction of rotation of the disk d by coupling the other roller k .

In order to be able to easily remove the completely folded strips, a piece of paper, sheet metal or the like can be placed on the disk d beforehand, which is removed with the folded strips. If a binding agent is to be used, it can be applied by hand or by machine both between the individual strips and between the individual layers, as desired.

In the event that a strongly adhesive binding agent causes the cut strips to adhere to the cutting knife e , a gripper can be arranged which retains the cut strips on the plate d. In order not to obscure the drawing, and since such a gripper is only necessary to a limited extent and is of secondary importance for the essence of the invention, it is not shown in the figures. If the strips are to be arranged in the form of a long band or on a cylinder, a prism, cone or a pyramid, the disk d is to be replaced by a long plate or the other body, the advance of which is also carried out with the movement of the cutting blade in is appropriately associated.

It should also be mentioned that it is considered immaterial whether the advance of the disk d or the corresponding parts as described here, or by other embodiments, e.g. B. is done using gear drives, friction wheels, etc., or the movement of the scissors is not done by hand, but by machine; the feed of the material to be cut could also be effected automatically. For the nature of the combination, it is also irrelevant whether, as described here, the base for the cut strips is moved with respect to the scissors, or whether the scissors are moved and the support remains at rest. It is essential to combine a device for cutting up plate-shaped! Material in strips with a device for arranging these strips in slices at the same time.
