    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.

    Abstract: The packaging machine includes a wrapping tunnel, adapted to form a tube of plastic film around a group of articles and a feed conveyor, adapted to feed articles to be packaged toward the wrapping tunnel. An elevator is positioned between the feed conveyor and the wrapping tunnel, and is movable vertically from a lower position, to receive articles coming from the feed conveyor, to a higher height, to transfer articles to the wrapping tunnel. A pusher is arranged to push articles to be packaged from the elevator into the wrapping tunnel. An auxiliary conveyor is also provided between the feed conveyor and the elevator. An upender is associated with the auxiliary conveyor, adapted to be arranged selectively in an active position, to co-act with the auxiliary conveyor to upend articles coming from the feed conveyor and transfer them toward the elevator, and in a deactivated position.

    Abstract: The grinding unit includes a slide provided with a movement towards and away from the disc-shaped cutting blade. On the slide, at least a first grinding wheel and a second grinding wheel are arranged so as to act on a first flank and on a second flank of a cutting edge of the disc-shaped cutting blade. The first grinding wheel and the second grinding wheel are respectively carried by a first arm and by a second arm that are mounted so as to rotate around a respective rotation axis with respect to the slide (115) in order to move towards and away from the disc-shaped cutting blade. The first arm and the second arm are associated with angular locking members adapted to lock the first arm and the second arm in a respective operative angular position with respect to the slide.

    Abstract: The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller, and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound.

    Abstract: 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.
