What's My Line?

PC Industries' Woolley believes register controls are still a necessity for electronic line shaft systems, and that automatic register controls can easily be added.

Woolley sees registration control of the electronic line shaft system as an effective way to match cylinder circumference to the image on the web. Registration of the station to the web can be accomplished using advance or retard keys, which add or subtract pulses to the motor drive, and by adjusting the base rate multiplier, either during makeready or run mode.
