    摘要： 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.

    摘要： A rewinding machine (2) is described with a first winding cradle defined by a first winding roller (1) a second winding roller (3) and a third winding roller (7). The rewinding machine comprises a fourth winding roller (21), defining with the first winding roller (1) and the second winding roller a further winding cradle in which the web material (N) starts winding around a winding core (A2). Winding is completed in the winding cradle formed by first, second and third winding rollers (1, 3, 7).
