PERIPHERAL REWINDING MACHINE AND METHOD FOR PRODUCING LOGS OF WEB MATERIAL

摘要

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 i s 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 axi s of said first winding roller and protrudes from the profile of the roller. T he 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 wit h the web material in the winding space defined by the three rollers to cause severing of the web material at the end of winding.
