SYSTEM FOR THE CONTROL AND MANAGEMENT OF FABRICS
Described is a system for managing and controlling fabrics comprising: a first station for moving a fabric, a second station for moving said fabric operatively connected to said first station, a light source positioned in an intermediate position between said first station and said second station configured for illuminating from the bottom upwards a predetermined portion of said fabric, an optical device for acquiring an image or a video of said predetermined portion of said fabric, a data processing and storage unit connected to said optical device and configured to associate with said image or video of said predetermined portion of said fabric identification information of said fabric.
Rewinding machine
Rewinding machine comprising a drive unit (1) for supplying a paper veil (2); a winding unit (3) for winding the paper veil supplied by the drive unit into a coil (W) around a winding core (4), comprising a primary roller (6) and a secondary roller (7) rotating in contact with the winding core (4), and a pressure unit (30) provided with a rotating roller (A, B, C) on the coil (W) that is being formed; a core exchange unit (5) for ejecting the formed coil (W) from the machine at the end of a winding cycle and inserting a new core to be wound; separation means (11) for interrupting the continuity of the paper veil at the end of a winding cycle; means for winding a drawing flap (34) of the veil (2) on the new core (4) at the beginning of a new winding cycle.

Winder and a method for winding a roll from a fibrous web
The present invention relates to a w winder (1) for winding a web roll (2) from a fibrous web such as a paper web or a web of non-woven material paper (2). The winder (1) comprises two support rolls (3, 4) for supporting the web roll (2) during reeling and a core shaft (5) for winding the paper reel (2). At each longitudinal end of the core shaft (5), there is a carrier chuck (6) in which the core shaft (5) is rotatably journalled. The carrier chucks to are arranged to be movable in a frame towards or away from the support rolls (3, 4) and a rider roll (8) is arranged to be capable of acting against the web roll (2) being wound. The rider roll (8) is carried by a rider roll beam (9) and the rider roll beam (9) is arranged to be movable in the frame (7) such that the rider roll (8) can be moved towards or away from the support rolls (3, 4). There is at least one actuator (10) for moving the rider roll beam (9) towards or away from the support rolls (3, 4); and at least one load cell (12) arranged to detect the force between the rider roll (8) and the web roll (2). The winder (1) also comprises at least one actuator (11) for moving the carrier chucks (6) of the core shaft (5) independently of the rider roll beam (9) and the winder (1) comprises at least one load cell (13) arranged to detect the force with which the carrier chucks (6) act on the core shaft (5). The winder (1) also comprises a logic control system (14) connected to the load cells (12, 13) such that the logic control system (14) receives measured values for the force between the web roll (2) and the rider roll (8) and the force with which the carrier chucks (6) act on the core shaft (5). The logic control system (14) is programmed to control movement of the carrier chucks (6) and the rider roll beam (9) such that the sum of the forces detected from the load cells (12, 13) and the force resulting from a calculated weight of the web roll (2) corresponds to a set value for the force between the web roll (2) and the support rolls (3, 4). The invention also relates to a corresponding method for operating the winder.
