Abstract
In order to prove the applicability of the research for pneumatical aclions reported previously1, 4, 5) to practical use, the lap feeding tests were repeated under various conditions with cotton blended for 20′s.
As a result of those tests, the empirical equations showing a tendency to vary in amount of the wastages, were found in agreement. Those experimental conditions are the revolution of taker-in cylinder and cage cylinder, the quantity of lap feed, the suction force by cage blower, and the varied width between undersheet anp taker-in cylinder.
The values of the empirical equations almost agree with those of experiments within the range of 0.04_??_0.07 probable errors, except for 0.50 concerning percentage of the materials separated from taker-in cylinder by the edge of mote-knife.
