Abstract
There have been hardly any published experiment on the winding of roving in recent years. The author begins by pointing out measurable factors concerning the winding of roving and divides then into two groups: the first group of variables are those affects winding and the other group are those affected by winding. We have investigated how to measured these variables. For this purpose a test flyer was developed for the experiment under review and it was compared with an ordinary flyer. The measuring flyer was found good enough for use in the experiment.
We have also developed a method by which the magnitude and the type of presser pressure can be changed at will. The experiment on the effect of presser pressure was made by this method.
The experiment showed that the effect of presser pressure was clearly discernible if roving-winding around the presser paddle was 1 turn, but that the effect was hardly distinguishable if the winding was 2 or 3 turns. The latter fact was pressumably because the effects of some other factors in presser pressure were stronger. The experiment has also shown clearly that winding draft affects the weight of roving, greatly and that the average value of winding tension, too, affects the weight of roving.
