Description
Bewegungseinrichtung für Wickelfilme Umwickelvorrichtungen für Filme, Papiere u. dgl., bei denen das Wickelmaterial zwischen Wickelrollen verschiedenen Durchmessers umgewickelt wird, haben im allgemeinen eine Antriebsvorrichtung, die mechanisch z. B. in Lochreihen des zu wickelnden Materials eingreift. Das schadet natürlich auf die Dauer dem Material, und gerade bei Oszillographen-$Imstreifen sind Verzerrungen in der Mitte des Streifens unangenehm.Moving device for wrapping films Wrapping devices for films, Papers and the like, in which the winding material is different between winding rolls Diameter is wrapped, generally have a drive device that mechanical z. B. engages in rows of holes in the material to be wound. That hurts Of course, in the long run, the material, and especially with oscilloscope- $ stripes distortions in the middle of the strip are uncomfortable.
In dem deutschen Patent 444 34$ ist eine Vorrichtung für Wickelrollen, zwischen denen das Material umgewickelt wird, beschrieben, bei der die Abwickel- und Aufwickelrolle sich gegenseitig durch Reibung mit gleichmäßiger Umfangsgeschwindigkeit mitnehmen.In the German patent 444 34 $ is a device for winding rolls, between which the material is wrapped, in which the unwinding and take-up reel mutually by friction at a uniform peripheral speed take along.
Diese Vorrichtung wird gemäß der Erfindung für Oszillographen angewendrt. Dabei ergibt sich der Vorteil, daß Beschädigungen des Films vermieden sowie ganz gleichmäßige und insbesondere hohe Filmgeschwindigkeiten erzielt werden können.According to the invention, this device is used for oscilloscopes. This has the advantage that damage to the film is avoided and entirely uniform and especially high film speeds can be achieved.
Bei der gezeichneten Ausführungsform der Erfindung liegen die Wellen der Abwickelrolle 1z, Aufwickelrolle 13 und der Antriebswalze 16 verschiebbar in den Nuten 14 bzw. i4'. Über die Wellen sind an beiden Seiten elastische Bänder i i zum stärkeren Zusam: menhalt gelegt. Der Film 15 wird beim Wikkelvorgang über Spannrollen in leicht ersichtlicher Weise an dem die Kurven zeichnenden Lichtstrahl von oben nach unten vorbeigeführt, wenn die Antriebswalze 16 in der Pfeilrichtung von einem beliebigen Motor gedreht wird. Als rauhe Oberfläche der Antriebswalze eignet sich ein Gummiüberzug o. dgl.In the illustrated embodiment of the invention, the shafts of the unwinding roller 1z, the winding roller 13 and the drive roller 16 are slidable in the grooves 14 and i4 '. Elastic bands ii are placed over the waves on both sides for greater cohesion. The film 1 is 5 at which the curves drawing light beam passed upon Wikkelvorgang over tensioning rolls in a slightly more apparent manner from top to bottom when the drive roller is rotated in the arrow direction from any motor sixteenth A rubber coating or the like is suitable as the rough surface of the drive roller.
Mit Vorteil verwendet man Filme mit besonders rauher Rückenfläche.It is advantageous to use films with a particularly rough back surface.
Statt der vertikalen Anordnung kann natürlich auch eine horizontale gewählt werden.Instead of the vertical arrangement, of course, a horizontal one can also be used to get voted.
