    Abstract: Paper converting plant including a rewinder adapted to produce paper logs and having an inlet for feeding a paper web, a winding station where the logs are formed and an exit station for unloading the finished logs. The rewinder has walls delimiting a chamber inside which the logs are formed, and an air suction channel at a lower part of chamber. The suction channel exerts a suction causing the formation of an air flow directed from the top to the bottom inside the chamber. The chamber includes two semi-chambers communicating with the air suction channel such that a vertical air flow directed downwards is generated in each of them, the chamber being provided with a manner for regulating the vertical air flows providing vertically oriented identical air flow rates in the semi-chambers.

    Abstract: Rewinder for the production of paper logs adapted to guide and transversely pre-cut a paper web along a predetermined path, adapted to wind a predetermined amount of the paper web on a core in a winding station, and including a threading mechanism for threading the web along said path. The threading mechanism includes a dragging unit provided to engage the web to drag it along the path with a predetermined feed direction and at least one dragging member to engage a respective flap of the web preceding the production of the logs. The dragging unit is located downstream of the winding station and is adapted to release the flap of the web from the dragging member, the release means being arranged downstream of the dragging so as to intercept the flap of the web and disengage it from the dragging while the web is fed.

    Abstract: An embossing system including: an embossing unit with at least one embossing roller arranged to emboss a web of paper intended to be joined with a further web by gluing; and a gluing unit associated with the embossing unit, with a tank containing the glue used to perform the gluing and a glue dispensing device including a cliche roller adapted to distribute by contact the glue contained in the tank on one of the webs while the embossing is performed, the cliche roller rotating with a pre-fixed angular velocity around an axis parallel to said at least one embossing roller. The system further includes: a sensor to produce electrical signals having amplitude and/or frequency related to the vibrations at which the cliche roll is instantaneously subject.

    Abstract: Device for controlling the sharpening state of a blade (2) having a cutting edge (20) delimited by two sides (21, 22) converging towards a plane (X) that contains the cutting edge itself. The device comprises two control surfaces each of which is in contact with a corresponding side (21, 22) of the cutting edge (20) and is connected with a transducer (R4), which produces an electrical displacement signal (S4) proportional to a displacement of the control surface with respect to said plane (X). Furthermore, the device comprises a processing unit (E) that receives said displacement signals (S4) and compares them, emitting an error signal if the comparison produces a value that exceeds a predetermined limit. The control surfaces are the surfaces that delimit an external groove (40) of a roller (4) that is free to translate along an axis (A4) perpendicular to said plane (X) and spaced from the blade (2) by an amount such that said cutting edge (20) passes in said groove (40).

    Abstract: Apparatus for the production of a paper web, comprising: a first embossing unit (1) with a first embossing cylinder (2) and a corresponding counter-cylinder (3) for embossing a first paper ply (4); a second embossing unit (5) with a second embossing cylinder (6) and a corresponding counter-cylinder (7) for embossing a second paper ply (8), such that, once embossed, the said plies have a series of oppositely oriented reliefs (R4, R8), said embossing units (1, 5) being synchronized so that the said reliefs are nested into each other; a sizing unit (1C, 2C, 3C) associated with said first embossing cylinder (2) to distribute a predetermined amount of glue on the side of the second ply (8) opposed to that from which the respective reliefs (R8) emerge; means (11) for joining to each other the plies (4, 8) exiting from the apparatus. The apparatus comprises means (12) to form, on said second ply (8), a series of further reliefs (RC) oppositely oriented with respect to those (R8) previously formed by the second embossing unit (5), creating, on the same second ply (8), a step (S) between each further relief (RC) and the corresponding relief (R8) produced by means of the second embossing unit.
