System for handling cardboard reels to feed machines that produce cardboard tubes, comprising a station (F) for picking up the reels configured to receive a stack () of overlapping cardboard reels (), a station (U) for unwinding of the reels, and handling means (D) for moving the reels () along a predetermined path. The means (D) for moving the reels comprise pneumatic means intended to pressurize a space (S) inside the stack of reels, in which said space includes the interface between an uppermost reel of the stack and the underlying reel, and gripping means configured and controlled to perform grip and release of the highest reel in the stack respectively.

Plant and process for handling cardboard reels

Embossing unit comprising a fixed structure () and a mobile structure () configured to be moved to and from the fixed structure (), a first embossing assembly (LA), a second embossing assembly (UA) and a gluing assembly (GA), wherein the first embossing assembly (LA) comprises a first engraved steel roller () and a respective rubber counter-roller (), wherein the second embossing assembly (UA) comprises a second steel engraved roller () and a respective rubber counter-roller (), and wherein the gluing assembly (GA) is mounted on the mobile structure (). The first embossing assembly (LA) and the engraved roller () of the second embossing assembly (UA) are mounted on the fixed structure () while the rubber counter-roller () of the second embossing assembly (UA) is mounted on the mobile structure above the gluing unit (GA).

Embossing unit

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.

Rewinding machine and method for the production of logs of paper material

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.

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.

Paper converting plant

Rewinder for the production of logs. A feeding element adapted to supply a paper web. A guide element adapted to guide sequentially several cores along a predetermined path between a station for feeding the cores and a winding station in which a predetermined amount of the web is wound on each core. A winding element adapted to wind the paper web on the cores in the winding station. The guide element includes a guide with a curved end section that ends in the winding station and in cooperation with the winding element, delimits a channel crossed by each core before reaching the winding station.
