ABSTRACT:
The machine cuts a roll or log (L) of web material into a plurality of small rolls (R). It includes a unit (17) rotating about an axis (A--A) parallel to the axis of the log (L) to be cut. The unit carries a cutting blade (19) rotating about an axis (B--B) parallel to the axis (A--A) of the unit (17). A driving device (61, 63) moves the cutting tool (19) into a reciprocating forward and backward motion parallel to the axis of the log (L) to be cut. At least at the time when the blade cuts the log, the blade moves parallel to the moving log at a translation speed substantially equal to the feeding speed of the log (L), so as to allow the cutting of small rolls (R) without stopping the log (L).
