mogene Trocknung der Papierbahn wird durch beidseitige Anordnung von Elektrodengruppen ausgeschlossen. is completely smooth; it can z. B. wrinkles or bulges have formed. An inho- 40
Mogeneous drying of the paper web is prevented by the arrangement of electrode groups on both sides.

gibt sich aber das Problem der (ersten oder Wieder-)
Einführung der bis zu mehreren Metern breiten Papierbahn zwischen den Elektroden, die aus Gründen des
Wirkungsgrades nur wenige Millimeter Abstand von
der Papierbahn (und damit voneinander) aufweisen. 50In the known opposite arrangement
of the electrode groups according to GB-PS 11 81 687 - «5
but there is the problem of (first or re)
Introduction of the up to several meters wide paper web between the electrodes, which for reasons of
Efficiency only a few millimeters away from

Papierbahn deren leichte Einführbarkeit gewährleistet 55
ist, ohne daß die räumlichen Abmessungen dieser Einrichtung wesentlich über die Abmessungen einseitiger
Bahntrocknungsanordnungen hinausgehen.The object of the present invention is therefore to provide a device of the generic type for capacitive stray field drying of paper webs, in which despite drying on both sides
Paper web that is easy to insert 55
is, without the spatial dimensions of this device substantially on the dimensions one-sided
Go beyond web drying arrangements.
daß zwischen aufeinanderfolgenden Umlenkungen der 60
Papierbahn jeweils nur eine Gruppe von zusammengehörigen Elektroden auf einer Seite der Papierbahn liegt.
Um die entstehenden Dampfschwaden abzuführen, ist
ferner mit Vorteil eine zusätzliche Heißlufttrocknung
vorsehbar. 65According to the invention, this object is achieved by
that between successive diversions of the 60
Paper web only one group of associated electrodes lies on one side of the paper web.
In order to dissipate the resulting vapor plumes
an additional hot air drying is also advantageous
predictable. 65
Lehre liegen in der leichten Einführbarkeit der Papierbahn und in der kompakten Bauweise. Letztere ist z. B.The advantages of a device according to the disclosed
The teaching lies in the ease of insertion of the paper web and in the compact design. The latter is z. B.
