There are to kinds of sections of spinning pins now used enera.ll : round and rectangular. The round is weak and breaks easily. The rectangulan gives undue resistance to sliver. Especially, the top comb pin for worsted spinning shows these defects conspicuously. To make an excellent top comb pin, an ellptical section seems best. In this way, the author has studied theoretically the top comb pin of an elliptical shape.<BR> The results obtained are as follows : The resistance which the elliptical pin gives to sliver decreases to half the resistance of the flat pin. It is almost equal to the resistance of the round pin. The strength increases about twofold as compared hith that of the round pin. Thus, it has been confirmed that the elliptical pin is much more excellent than the usual round or flat pin.
