摘要： Cutting-off machine for the transversal cutting of logs of paper material, comprising:
a structure (SC) on which are moved the logs;
a cutting unit (CU) with a blade (2);
a grinding unit for sharpening the blade;
a device for positioning the grinding wheels with respect to the blade (2);
wherein
the positioning device comprises a primary carriage (4) and two secondary carriages (42, 43) driven by respective actuators;
there is an optical sensor (100) that detects a cutting edge (200) of the blade (2);
in a phase of operative positioning of the grinding wheels which involves sharpening the blade following the contact of the grinding wheels with the blade, the abrasive side of the grinding wheels is pushed against the blade with a thrust having a predetermined value.-

摘要： Rewinding machine for producing paper logs by winding a paper web, include: an element 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 pad is mounted on the pad-holder device by an elastic support which deforms elastically, such that the pad moves elastically towards the pad-holder, when it is subjected to a pressure and moves automatically in the opposite direction returning to its previous position when the pad is no longer subjected to a pressure.

摘要： 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.

摘要： Plant for the production of paper logs, including a number of operating units configured to produce logs of paper material starting from a web of paper material unwound from one or more corresponding reels and slaved to a control unit that, in turn, is configured for driving the operating units such that each of them has a predetermined production speed. The said control unit is programmed to process data contained in a database individually associated with each reel and representative of defects classified according to a predictive classification 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 receives position data related to the instantaneous diameter of the reel from a corresponding detection means. The control unit is programmed to modify the production speed in function of the instantaneous position and of the class of each of the defects.

摘要： Method for the handling of parent reels in paper converting plants, comprising the following steps: (a) providing at least one platform with a base adapted to support a parent reel in a waiting station and at least one unwinder (S) adapted to receive said reel in an unwinding station where the parent reel is unwound; (b) positioning a parent reel (1) on the platform at the waiting station; (c) transporting the parent reel (1) along a predefined path from said platform to said unwinder (S) by means of a bridge crane (CP) equipped with movable arms (BC). The step (c) is preceded by a first step consisting in the temporary association of two pins (P) to the arms (BC) of the bridge crane (CP) and by a second step consisting in inserting the two pins (P) in two opposite bases of the parent reel (1) using the same arms (BC); and the step (c) involves the transport of the reel (1) along a path comprising at least one ascending or descending portion with the pins (P) thus inserted into the parent reel (1).

摘要： 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.

摘要： Device for controlling a flow of cardboard tubular cores (1) adapted to produce logs of paper material and intended to be stored in a collection point (2) placed downstream of the same device, including more conveyors (5; 7) each of which is adapted for carrying the said tubular cores (1) up to the entry point (6D) of a respective guide channel (6) having an entry point (6D) and an exit point (6F), interception devices (8) adapted for intercepting the tubular cores (1), the interception devices being arranged and acting on each of the channels (6) to adjust the flow of the tubular cores through the respective exit points (6F), and programmable device (UE) adapted for activating and deactivating the interception device (8). The interception devices (8) are adapted to selectively form two nips (N1, N2) inside the guide channel (6), the nips (N1, N2) being selectively formed at a predetermined distance from each other.
