[Include all page skew application information on a single page?]
Page Skew
The precise stops and positioning of copy in automatic photography
requires the pinpoint accuracy photoelectric controls can provide.
Page sheets are passed on two narrow conveyor belts. Compact through-beam
sensors are located between the conveyor belts such that the light
beams both get obscured by the leading edge of the page at the same time.
A relay is wired to operate when one light signal is received
without the other. If such a skewed page passes, the edge is not
sensed by both sensors at precisely same time, and the relay operates
to stop the conveyor. Skew tolerance is set as delay time on the time
delay relay.
Skew can be detected ''on the fly'' without
actually stopping the pages.
