ABSTRACT:
An improved microcomputer controlled winder for attenuating a plurality of streams of molten glass issuing from a bushing into fibers and for collecting a strand of such attenuated fibers into a package. The microcomputer controls the winder speed in accordance with error between programmed data and a winder collet speed signal from a tachometer. The tachometer signal is modified to compensate for temperature variations in the bushing when a package is started after the bushing has been shut down for a period of time.
