Device and method for guiding a continuous web by means of a pivotable apparatus

A device for guiding an endless web, comprising:

• a first positionable roll which guides the endless web directly to an additional positionable roll with a predetermined wrap angle on each positionable roll, shafts of said positionable rolls lying parallel to one another in a plane and being held by a frame;
• the web being fed to and led away from the positionable rolls via a respective first stationary roll and a respective additional stationary roll;
• the frame being pivotable relative to the stationary rolls about a first axis of rotation which is substantially perpendicular to said plane in order to modify a position of an edge of the web in a direction of the roll shafts;
• and
• the frame being pivotable relative to the stationary rolls about a second axis of rotation one component of which runs parallel to a movement direction of the web between the first and additional positionable rolls.

A device for guiding an endless web in a printer or copier, comprising:

• a smudgeable toner image applied to the endless web in a transfer station, and the endless web being supplied to a fixing station for fixing of the toner images;
• after the fixing station in a direction of transport of the web, a draw-off device that draws off the web from the transfer station in freely suspended fashion with a predetermined tensile force;
• and
• the draw-off device being pivotable in order to correct a one-sided sagging of the web.

A method for guiding an endless web in a printer or copier, comprising the steps of:

• after application of a smudgeable toner image in a transfer printing station, supplying the endless web to a fixing station for fixing of the toner images;
• as seen in a movement direction of the web, providing after the fixing station a draw-off device that draws off the web from the transfer printing station in freely suspended fashion with a predetermined tensile force;
• and
• pivoting the draw-off device in order to correct a one-sided sagging of the web.
