Abstract

Abstract A digital pulse deleter for use with digital control systems of electric motors driving work stand rolls in processing lines to afford selective adjustment of motor speeds calibrated in terms of percentages of elongation between successive work stands. The deleter can be adjusted by readily made changes in electrical interconnections to be determinative of what percentage of input pulses will and what percentage of such pulses will not be subject to deletion by selector switches. Operation of the selector switch permits selection of the increments of pulses subject to deletion that will be actually deleted with such increments being calibrated as a percentage or a per unit value of elongation or draw. The percentage of total deleter input pulses not subject to deletion is determinative of the maximum elongation or draw ratio to which the deleter will be so calibrated.
