    Abstract: 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.

    Abstract: The invention relates to a device and method for cleaning the surface of a printing roll, such as an anilox roll. The device includes a laser-equipped assembly adapted to project a laser beam on the surface of the printing roll. The laser-equipped assembly uses a reflector and a lens to guide the laser beam along a predetermined path on the surface of the printing roll. In some embodiments, an autofocus system may be included to move the lens so that the desired focal point for the laser beam on the printing roll surface is achieved.

    Abstract: Apparatus for gluing the final tail of rolls or logs of wound sheet material includes a glue distributor device located below an opening in a roll down table. The tail of the roll is separated from the roll by a tail separating unit upstream of the opening. The gluing distributor device includes a tank containing glue, a rotatable pick up roll located inside of the tank and partially immersed in the glue, and a glue distributor roll positioned externally above the tank and provided with at least one paddle. The pick up roll picks up glue as it rotates, and the rotating paddle contacts the pick up roll and picks up glue as the glue distributor roll rotates. The paddle rotates into the opening in the roll down table, and glue is transferred from the paddle to a roll as the roll rolls over the opening. A cull roll can be culled without applying glue to the roll by mounting a cull roll support projection on the glue distributor roll which is not long enough to contact the pick up roll. The cull roll support projection is positioned in the opening in the roll down table when the cull log rolls over the opening.

    Abstract: A method of cutting an elongated multi-ply flat surfaced ribbon of web material which includes advancing the ribbon along a linear path while rotating a pair of cantilever-mounted drums on opposite sides of the path to flank the ribbon flat surfaces, the drums each having a plurality of axially extending slots in the periphery thereof. A saw blade is adjacent the path and orbits through the path so as to have the blade orbit intersect the drum slot orbits to transversely cut the ribbon while the saw is advancing parallel to the linear path.
