A disclosed method is a method of manufacturing a battery including a wound electrode assembly in which a first separator, a negative electrode plate, a second separator, and a positive electrode plate are wound together. The method includes steps of winding the first separator, the negative electrode plate, the second separator, and the positive electrode plate onto a winding core, to prepare a wound electrode assembly, and removing the wound electrode assembly from the winding core. The winding core includes a first component and a second component. In the step of removing the wound electrode assembly from the winding core, at least one of the first component and the second component moves in a direction in which a distance between the first component and the second component decrease so that a diameter of the winding core decreases. Thereafter, the wound electrode assembly is removed from the winding core.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

Rewinder for making paper logs of paper material including a detection system with optical means adapted to detect, in a succession of predetermined detection times, a succession of diameters assumed in such times by a log being formed in a winding station and a programmable electronic unit which compares the diameters measured by the optical means with a succession of corresponding preset diameters and to calculate a sequence of differences. The processing unit receives a signal relating to the value of the actual diameter of the completed log and determines a parameter related to the trend over time of the differences. Elements for adjusting the thickness of the paper web automatically adjust said thickness if the parameter is between predetermined values.

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.

The device incorporates a mobile station with: a first shaft to support a movable reel and to actuate rotation of the movable reel around the first shaft; a grip for gripping and releasing the movable reel from a first side of the movable reel closest to the first shaft; and a transporter to move the movable reel in the direction of the first shaft between the mobile station and a loading position. The process handles one single reel in each change, reducing labor and simplifying logistical management of reels. Likewise, the reels are handled from one single side, the side closest to the first shaft. Therefore, space is freed up on the other side, providing more available space.

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 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.

Disclosed herein is an extraction assembly for producing coreless logs. The extraction assembly includes a rectilinear transporter (20) of a log (11) wound about a disintegrable core (12), and a gripping device (30) for a portion of the core (12) projecting from the log (11), wherein the rectilinear transporter (20) has a transverse transport direction with respect to a log advancement direction of the log (11) along the converting line (100), and has an alternating transport direction back and forth in opposite directions, and the rectilinear transporter (20) contains a first portion for being received within the converting line (100), and a second portion for being placed outside the converting line (100), in which the second portion is aligned with respect to the first portion along the transverse transport direction. Also disclosed herein are a converting line containing the extraction assembly, and methods for producing coreless logs.

An assembly for handling reel spools, comprising linear support rails, having a first end and a second end, arranged parallel to each other, and a reel spool cart arranged on the support rails, the support rails being arranged at a first distance from each other, the first distance being greater than axial length of the reel spool, and the cart being provided with a hoisting device configured to hoist the reel spool vertically from beneath of at least one of the support rails to at least partly above at least one of the support rails.
