Document Type and Number:
Japanese Patent JPS4996730
Kind Code:
A
Abstract:
A method and an apparatus are described to enable one of two independently driven strips to be stopped for a predetermined period and then restarted in synchronism with the other strip which has been running continuously. Stoppage markers are provided on the first strip and synchronizing markers, which are interrupted when this first strip is to be stopped, are provided on the second strip. An integrator accumulating the output of a first sensor, responsive to the synchronizing markers on the second strip, feeds a coincidence circuit, also receiving the output of a second sensor responsive to the appearance of a stoppage marker on the first strip, which arrests the drive of the latter strip upon detection of a stoppage marker and restarts that drive after a period of interruption determined by the time constant of the integrator.
