<p><P>PROBLEM TO BE SOLVED: To provide a method and a machine of decreasing a change of a sheet web tension in case of conducting a timing control of a transfer sheet 2 in a sheet transfer device 1. <P>SOLUTION: When the transfer sheet 2 is guided through a transfer passage 20 of a transfer gap 3 of the sheet transfer device 1, a strong influence is given to the sheet web tension 204 and 205 before and behind the transfer gap 3 by contact sections B1 and B2. Forward and/or backward guide member is mutually time-asynchronously moved before or behind the transfer gap 3 in order to decrease the change of the sheet web tension, and that at least decreases the change of the sheet web tension in case of passing the transfer sheet 2 through the transfer gap 3. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
