Abstract

Der Hohlzylinder 2 weist einen Innenkörper 3 auf, der mittels einer zentrisch zum Hohlzylinder 2 angeordneten, mit kleinerem Radius als dessen Innenradius beträgt, ausgebildete Teilzy­ linderfläche 12 einen sichelförmigen Raum bildet, in welchem ein Unterdruck bei Rotation des Hohlzylinders 2 entsteht. Dadurch wird durch die Bohrungen 11 des Hohlzylinders Luft aus dem Be­ reich abgesaugt, wo eine Warenbahn den Hohlzylinder 2 um­ schlingt. Dies führt zu einer festeren Haftung der Warenbahn an dem Hohlzylinder 2. The hollow cylinder 2 has an inner body 3, which means one arranged centrally to the hollow cylinder 2, with a smaller one Radius as its inner radius is trained sub-cycle Linderfläche 12 forms a crescent-shaped space in which a Negative pressure arises when the hollow cylinder 2 rotates. Thereby is through the holes 11 of the hollow cylinder air from the loading sucked rich, where a web of the hollow cylinder 2 um loops. This leads to a stronger liability of the web the hollow cylinder 2.
