US Patent:
53187962, Jun 7, 1994
Filed:
Feb 12, 1992
Appl. No.:
7/834424
Inventors:
William A. Torpey - Rochester NY
Raymond A. Ehnot - Brockport NY
Charles F. Puckhaber - Loveland CO
Assignee:
Eastman Kodak Company - Rochester NY
International Classification:
B65H 23188
US Classification:
427 8
Abstract:
A method and apparatus is provided for controlling the speed of a slave drive roller in a coating machine. Speed of the slave drive roller at a second coater is regulated by an adaptive gain allowing greater tolerances when not at run speed. That is, in addition to normal speed correction, the system accommodates greater web speed fluctuation during threadup, acceleration, and deceleration. This accommodation may be based on the sensed position of the float roller or, alternatively, on the sensed rate of acceleration/deceleration of the master drive roller.
