<p>The shafts (e.g. 12a, 14a, 16a, 18a) of the sections of a printer-slotter machine are gear coupled (24,26; 28,30; 32,34; 36,38) and are set to the desired phase relation by a microcomputer control while coupled. The sections need not be de-coupled during set up. During normal operation, following set up, the section shafts are mechanically locked in phase register. The phase register control system is appropriate for retro-fitting to existing printer-slotter machines. </p> |
