A material strip collection mechanism coiling fed material strip on a reel includes a vertically positioned reel bracket rotatable about a vertical axis between a first configuration and a second configuration. The mechanism further includes a first arm holding the reel and a second arm each rotatable to drive the reel and coil the material strip on the reel. With the reel bracket in the first configuration, the first arm is in a material strip collection position to allow the material strip to be coiled on each empty reel held by the first arm to form a full reel, while the second arm is in a standby position to allow the full reel held by the second arm to be replaced with a new empty reel.

An improved paper band delivery assembly for reliable high speed delivery of a turn-up paper band across a moving web of paper being wound onto a spool. The turn-up paper band is made ready for a turn up procedure by coiling a predetermined length of paper band suitable for a particular machine and retaining the coiled paper band in a reservoir pending deployment across a spool for a turn up procedure. The paper band may be coiled via manual operation or via automated operation. Coiling apparatus may be modularly replaced on a paper making machine. The coiled paper band may be supported within the reservoir on rollers, pins, or other items conducive to fast and reliable uncoiling.

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.

A method of forming a gum roll is provided. The method includes providing a strip stock having a first end, a first surface, and a second surface opposite to the first surface. The first end of the strip stock is coupled to a core fixture so the first surface interfaces with the core fixture. The strip stock is rotated to wind the strip stock onto the core fixture such that the first surface interfaces with the second surface to form the gum roll. The method further includes cutting the strip stock to form the second end when the gum roll is wound to an outer roll diameter, the outer roll diameter being greater than a diameter of the core fixture.

A winder includes a winding mechanism, a chamber, a vacuum pump, a conveying route and a product case. The winding mechanism winds a belt-shaped raw film around a winding core, the belt-shaped raw film being composed of a plurality of electrodes and a plurality of separating films. The chamber houses the winding mechanism. The vacuum pump sucks air into the chamber. The conveying route has a sealed outer space outside the chamber, an inner space of the chamber leading to the outer space in the conveyance route. The product case is disposed in the conveying route to house a plurality of winding products each formed by winding the raw film with use of the winding mechanism.

The machine (1) comprises: —an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N; S); —at least one winding station (15) comprising a winding device (25) and further comprising: guide members for guiding the strip (S) of web material, configured to form at least a loop of web material between a guide roller (43) and a log (B); and a cutting device (61) for transversally cutting the strip (S) of web material in an intermediate position between the log (B) and the guide roller (43), thus generating a tail edge, remaining on the log (B) being formed, and a leading edge, remaining fastened to the guide roller (43).

A winding machine for web-type materials, in particular film materials, comprises a feeding device and at least one winding shaft which is capable of being driven and designed to receive a winding core for the winding of the web-type film material, wherein the winding machine is allocated a system for regulating and/or reducing an electrostatic charge of the web-type material during the winding process.

The rewinding machine includes a first winding cradle formed between a first winding roller, a second winding roller and a third winding roller. The first winding roller and the second winding roller define a nip through which there pass the winding cores with the web material being wound around them. The rewinding machine also includes a feed path of the winding cores that pass between the first winding roller and the third winding roller. A second winding cradle is formed between the first winding roller, the second winding roller and a fourth winding roller. The rewinding machine also includes a rolling surface extending around the first winding roller and defining a feed channel of the winding cores.

A paper rewinding machine includes a rewinding assembly operable to produce coreless retail paper rolls.

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