Method for regulating the tension of a web

   
   

The tension of a web in a rotary printing press is regulated during passage of the web between at least first and second cylinders of at least one printing group. The two cylinders are driven using at least one drive mechanism. A distance between the two cylinders is varied to influence the web tension before, between and after the printing groups.

La tensión de una tela en una prensa rotatoria se regula durante el paso de la tela en medio por lo menos primero y de los segundos cilindros por lo menos de un grupo de impresión. Se conducen los dos cilindros usando por lo menos un mecanismo de arrastre. Una distancia entre los dos cilindros se varía para influenciar la tensión de la tela antes, entre y después de los grupos de impresión.
