ABSTRACT:
In precision winding of fibers onto a bobbin mounted on a mandrel, a suity positioned circuit of lag angle detector, differentiator, threshold and status latch detect the occurrence of a crossover event while a suitably positioned circuit of angle counter, turn counter and data latch record the absolute mandrel angle and the number of complete revolutions of the mandrel at each occurrence of the crossover event. A computer coupled to the status latch and data latch graphically depicts the absolute mandrel angle versus the number of revolutions at the time of each crossover occurrence. This graphic depiction simulates the crossover pattern, thus making it possible to observe the pattern without stopping the winding process to inspect the pattern visually.
