Abstract
A rewinding machine for the production of logs of web material around a tubular core includes a first winding roller around which the web material is fed, a second winding roller forming a gap with the first winding roller, through which gap the core is inserted, and a third roller mounted movably to allow the diameter of the log to increase and the log to be discharged at the end of winding. A blade is carried by a rotating member which is pivoted on the axis of said first winding roller and protrudes from the profile of the roller. The blade rotates in the same direction as the first winding roller at different speeds, so as to undergo a deceleration or an acceleration when it is in contact with the web material in the winding space defined by the three rollers to cause severing of the web material at the end of winding.
