Abstract
An emergency battery power supply for a ring-spinning or ring-twisting frame can be brought into operation by an automatic circuit to bridge brief power failures and effect programmed shutdown of the motors upon longer power failures, with the speed ratios between the motors being maintained substantially to standstill to avoid yarn breakage during shutdown.
