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 and.

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.

An apparatus for folding sheets and corresponding method, including at least a conditioning body, at least a folding unit and at least an extraction mean suitable to fold sheets in sequence of variable formats, maintaining high cadences and at the same time simplifying the structure for the maintenance operations and/or format-changes.

A slitting machine (500) includes a laminated film unwinding apparatus (540), a release liner recovery apparatus (550), a cutting apparatus (530), and a plurality of polymer substrate strip rewinding apparatuses (510, 520). The laminated film unwinding apparatus (540) is operable to unwind a roll of laminated film (542) comprising at least a polymer substrate (100) and a release liner (150). The release liner recovery apparatus (550) is operable to wind the release liner (150) that is released from the polymer substrate (100). The cutting apparatus (530) is operable to cut at least the polymer substrate (100) along a machine direction to divide the polymer substrate into strips. The plurality of polymer substrate strip rewinding apparatuses (510, 520) are operable to wind one or more strips of the polymer substrate (100) onto one or more rolls (512, 522). The slitting machine (500) is operable to carry out a method for forming rolls (512, 522) of coated films (100).

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.

A rewinding machine and a related method, the machine including three rollers having axes parallel to one another and perpendicular to the advancing direction of the paper, where two lower and upper winding rollers collaborate with a third oscillable roller under pressure on a roll or log being formed identifying a winding area, where the paper being wound passes over the upper winding roller and the finished roll comes out from an outlet opening defined between the lower roller and the third roller, where the cores for the rolls are fed one after the other by a conveyor and inserted by a thruster in a channel formed beneath the upper roller, the lower and upper winding rollers being supported in rotation at the ends of their axes in a mobile manner and being associated with an actuator device for a translation in a direction parallel to a first straight line joining the axes of the lower and upper winding rollers and symmetrical with respect to a growth straight line of the roll, where the growth straight line of the roll is arranged perpendicular to the first straight line joining the two axes of the lower and upper winding rollers and equally spaced between them.

There is described a magazine unit for a packaging machine comprising an inlet opening configured to allow for the introduction of a spindle carrying a wound-up web of packaging material into the magazine unit, at least one pair of housing seats configured to rotatably support the spindle carrying the wound-up web of packaging material, the respective housing seats being arranged side-by-side and distanced from the inlet opening, and a pair of guide rails, the guide rails being arranged side-by-side and each one extending from the inlet opening to one respective housing seat and being configured to guide the spindle from the inlet opening to the pair of housing seats.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

An improved tape delivery assembly for delivering a turn-up tape across a moving web of paper being wound onto a spool, the assembly being part of a paper web turn-up system, the tape being used to sever and transfer the leading edge of the cut paper web onto an empty spool. A secondary tape dispensing module may deliver a secondary turn-up tape while a primary tape delivery module is temporarily removed from the paper web turn-up system.
