Description
Es ist bekannt, Isolierbänder zur Herstellung von Schaumstoffisolationen in der Weise zu gewinnen, daß diese von einem Schaumstoffblock furnierartig abgeschält werden. Der Nachteil dieses Verfahrens ist, daß notwendigerweise der Schnitt durch viele Schaumstoffbläschen geht und dadurch selbst bei sehr kleinen Zellen die Oberfläche des Bandes nicht glatt sein kann, was aber aus Gründen der Maßhaltigkeit und Festigkeit beim Einsatz solcher Bänder zur Isolierung von Leitern, bei welchen es auf sehr genaue Einhaltung und Beibehaltung des Außendurchmessers, wie z. B. bei Fernkabeladern, ankommt, angestrebt werden muß.It is known, insulating tapes for the production of foam insulation to win in such a way that this peeled from a foam block veneer-like will. The disadvantage of this method is that it necessarily cuts through a lot of foam bubbles and thus the surface even with very small cells of the tape cannot be smooth, but this is for reasons of dimensional accuracy and strength when using such tapes to insulate conductors, which are very difficult exact compliance and retention of the outer diameter, such as B. for long-distance cable cores, arrives, must be striven for.
Nach der Erfindung werden solche Bänder in der Weise hergestellt, daß der Ausgangsstoff in den zweckentsprechend abgeschlossenen Zwischenraum zwischen zwei mittelpunktsgleichen, ineinandergestellten Zylindern eingefüllt und in bekannter Weise geschäumt wird, wobei der Zylinderabstand der Banddicke entspricht. Der so erhaltene Schaumstoffmantel wird dann durch eine mit der Bandbreite als Steigung im Schraubengang vorrückende Schneidevorrichtung in Bandform abgelöst, wobei es gleich ist, ob diese umläuft oder einer der Zylindermäntel. a In der Zeichnung stellt vor ca den Innenzylinder, b den Außenzylinder, c den Füllraum, d eine Ventilleitung, e den Einlaß für den Wirkstoff. Durch dieses Verfahren erhält das Band auf beiden Längsseiten eine glatte, nicht durch zerschnittene Zellen zerklüftete Oberfläche.According to the invention, such tapes are produced in such a way that the starting material is filled into the appropriately closed space between two cylinders with the same center point, nested cylinders, and foamed in a known manner, the cylinder spacing corresponding to the tape thickness. The foam casing obtained in this way is then detached in the form of a ribbon by a cutting device in the form of a ribbon, which advances in the screw thread with the ribbon width as the pitch, it being the same whether this runs around or one of the cylinder jackets. a In the drawing, in front of ca the inner cylinder, b the outer cylinder, c the filling space, d a valve line, e the inlet for the active substance. This process gives the tape a smooth surface on both long sides that is not jagged by cut cells.
