Abstract: Process for the production of paper rolls, including a step of producing logs (L) of paper material by winding a predetermined amount of paper web (W) about a respective longitudinal axis, a step of transverse cutting of the logs (L) to obtain rolls (RO) of predetermined length, and an intermediate step of transporting the logs (L) from a rewinder (R) that produces the logs (L) toward a cutting-off machine (CM) that cuts them transversely. The intermediate transporting step involves the handling of the logs (L) along a path comprising a lateral deviation, so that, as they advance, the logs (L) are subjected to the lateral deviation.

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: A rewinding machine for producing paper logs by winding a paper web, comprising: elements for feeding a paper web along a predetermined path at a predetermined feeding speed; web pre-cutting elements; web winding elements; web sizing elements, with a pad adapted to cyclically apply glue by contact on the web, the pad being mounted on a pad-holder device connected with a corresponding actuator. The web sizing elements are arranged upstream of a web winding station. The pad-holder device is controlled such that, when the pad contacts the web, the pad is moved with a speed lower than the speed of the web along the respective feeding path so as to cause a prolonged contact of the pad with the web while the pad and the web move.

Abstract: Calender for treating web materials, comprising a structure for supporting two heated rollers forming a nip, wherein each roller has surface reliefs (RR) and in an operational setting of the calender the reliefs of one roller are radially opposed to those of the other roller, each roller rotates with a predetermined angular speed around its axis, the rollers are heated by heating means, and each roller undergoes an axial elongation as a consequence of its heating. The calender comprises detection means (E1, E2; IS) adapted to detect the axial elongation of each roller and a programmable control unit (UCP) connected to the detection means and to the heating means. The control unit is programmed to determine the difference between the axial elongations of the rollers and emitting an alarm signal if the absolute value of this difference is greater than a limit value.

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: Process for the production of paper rolls, including a step of producing logs (L) of paper material by winding a predetermined amount of paper web (W) about a tubular core (C) oriented transversely with respect to a direction (PP) of entering of the paper web (W) in a rewinder (R) in which the winding is executed, and a step of transverse cutting of the logs (L) to obtain rolls (R) of predetermined length. The cores (C) are produced by a tube-forming machine (T) whose position is intercepted by the direction (PP) of the paper (W) entering the Rewinder®.
