PLANT FOR THE PRODUCTION OF PAPER LOGS

WIPO Patent Application WO/2018/109790

A3

Plant for the production of paper logs, comprising a plurality of operating units (A, B, C) configured to produce logs of paper material starting from a web (W) of paper material unwound from one or more corresponding reels (1) and slaved to a control unit (2) that, in turn, is configured for driving the operating units (A, B, C) such that each of them has a predetermined production speed. The said control unit (2) is programmed to process data contained in a database (5D) individually associated with each reel (1) and representative of defects (10-21) classified according to a predictive classification (I, II, III, IV) based on the effects of the defects in the production of the logs and further representative of the location of defects on the web unwound from the reel. The control unit (2) receives position data related to the instantaneous diameter of the reel by means of corresponding detection means (3; 4). The control unit (2) is programmed to modify said production speed in function of the instantaneous position and of the class (I, II, III, IV) of each of said defects (10-21).
