摘要： 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 said cutting edge (20) and is connected with at least one transducer (R1, R2, R4 ), which produces an electrical displacement signal (S1, S2; 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 (S1, S2, S4) and compares them, emitting an error signal if the comparison produces a value that exceeds a predetermined limit. The processing unit is connected to means (101, 102) for supporting and moving sharpening means (100).

摘要： Rewinder for making paper logs of paper material comprising a detection system with optical means (5, 50) adapted to detect, in a succession of predetermined detection times, a succession of diameters (DE) assumed in such times by a log (L) being formed in a winding station (W) and a programmable electronic unit (UE) which compares the diameters (DE) measured by the optical means with a succession of corresponding preset diameters (DT) and to calculate a sequence of differences (e1, e2,..., en). The processing unit (UE) receives a signal relating to the value of the actual diameter (DEK) of the completed log (LK) and determines a parameter (a) related to the trend over time of the differences (e1, e2, …, en). Means for adjusting the thickness (T3; EM; EX) of the paper web (3) automatically adjust said thickness if the parameter (a) is between predetermined values (aN) and (aP).

摘要： Rewinder for producing paper logs, comprising a winding station with a first winding roller (R1), a second winding roller (R2) and a third winding roller (R3) driven by corresponding electric motors (M1, M2, M3), comprising a detection system capable to detect a succession of diameters (DE) of the log (L) being formed in the winding station and a programmable electronic unit (UE) connected to the electric motors. The system compares the measured diameters with a succession of corresponding diameters of predetermined value (DT) and to calculate a sequence of differences (e1, e2,..., en) between these values (DE, DT). The electronic unit determines a parameter (a) related to the trend over time of the values (e1, e2,..., en). The electronic unit changes the relative speed of the first and second roll depending on the value of the parameter (a).

摘要： Rewinder for making paper logs, comprising a winding station (W) and a logs discarding device (SL). The rewinder comprises optical means (5, 50) capable of detecting, at a predetermined detection time, the diameter (DE) of a log (LK), and a programmable electronic unit (UE) for comparing the diameter (DE) detected by said means (5, 50) with a predetermined diameter (DT) and calculating the difference between said values (DE, DT). The detected diameter (DE) is determined upon detection of at least four points of an image of the edge (EL) of the log (LK) detected in said detection time and subsequent calculation of the diameter of all the circumferences passing through each group of three of said at least four points. The detected diameter (DE) is compared with a predetermined value (DT) and the the logs discarding device (SL) is activated if said difference exceeds a predetermined limit value.
