Rewinding machine and method for the production of logs, with means to control the final diameter of the logs

摘要

The rewinding machine comprises a winding roller ( 5 ) equipped with a moving axis to remain in contact with a log (R) being formed and allow the diameter of said log to increase. A member to control the action of said roller on the log (R) being formed is associated with the winding roller with moving axis. The control member is provided with a stop position that can be set to be reached before winding of the log (R) is completed. Winding of the log being formed is essentially completed without moving the axis of the winding roller with moving axis ( 5 ) in order to obtain a finished log always with a more or less constant diameter.
