    Abstract: The interfolding machine includes a first interfolding roller rotating around a first rotation axis and a second interfolding roller rotating around a second rotation axis parallel to the first rotation axis; wherein the first interfolding roller and the second interfolding roller form an interfolding nip therebetween. The interfolding machine further includes a first set of separation fingers associated with the first interfolding roller and arranged for reciprocatingly pivoting around a first pivoting axis parallel to the first rotation axis. The reciprocating pivoting movement of the first set of separation fingers is controlled by a first actuation mechanism including a first desmodromic cam. The interfolding machine also includes a second set of separation fingers associated with the second interfolding roller and arranged for reciprocatingly pivoting around a second pivoting axis parallel to the second rotation axis. The reciprocating pivoting movement of the second set of separation fingers is controlled by a second actuation mechanism including a second desmodromic.

    Abstract: The machine includes a feeding path for the logs to be cut and a cutting head arranged along the feeding path. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes at least a grinding unit, including at least one grinding wheel mounted onto a rotation shaft and co-acting with a side of the disc-shaped cutting blade to grind the cutting edge of the same disc-shaped cutting blade. A controlled approach system is also provided to move the grinding wheel towards the disc-shaped cutting blade.

    Abstract: The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

    IPC: B65H19/29

    Abstract: The machine for closing the tail end of logs of web material, includes an advancing path of the logs and, along the log advancing path, a tail end unwinding, positioning and sealing station. The tail end unwinding, positioning and sealing station includes an aperture that extends downwards from an inlet under the log advancing path. At least a first Coanda effect nozzle is placed at the inlet of the aperture, to generate a flow of air adapted to draw into the aperture the tail end of a log that is in the tail end unwinding, positioning and sealing station.
