Machine and method for winding strips of web material with means for the transverse cutting of the strips at the end of winding

A machine for forming logs of web material, the machine comprising:

• an unwinding section for unwinding parent reels of web material;
• and
• at least one winding station comprising:
• a winding device comprising a winding mandrel;
• guide members for guiding a strip of the web material, the guide members being configured to form at least a loop of the web material between a guide roller and a log arranged on the winding device;
• and
• a cutting device for transversally cutting the strip of the web material in an intermediate position between the log and the guide roller to generate a tail edge, remaining on the log being formed, and a leading edge, remaining fastened to the guide roller, wherein the winding mandrel is further provided with reciprocating translation motion in a direction parallel to a rotation axis thereof, in order to helically wind the strip of the web material around the winding mandrel.
