Abstract
Abstract A method and apparatus for controlling the simultaneous winding of glass strands into more than one package by sensing when a first package has reached a predetermined size, sensing when a second package has reached a predetermined size, determining when a predetermined period of time has elapsed after one of the packages has been sensed and increasing the distance between the packages and the strand guides when either both packages have been sensed or the predetermined period of time has elapsed.
