Device for discharging webs

Image Number 2 for United States Patent #6676062.

The present invention concerns a device for discharging webs at a predetermined web speed in an uninterrupted process, in which the web end (37) on an initially active take-off roll (2) must be placed against and joined to the beginning of a web on a roll initially situated in a waiting station. To this end, the web tension in the processing line (39) is adjusted to a predetermined target value. In order to influence the web tension in additional areas during the joining of the web ends (37), a web accumulator equipped with an externally controlled drive is provided in addition to the compensation system.
