The only beltsare those from the motor pulleys direct to the frames. Fric-tion is therefore almost entirely eliminated. Or, to state itmore exactly, friction is reduced from i6% to 22% down to4% to 5%. There are advocates of the old methods of electricdriving spinning that will no doubt take exception to thestatement that there is 16% to 22% friction in such drives. Inreply I would simply say that readings on this subject froma number of mills disclose the fact that my statement is borneout in actual The above cuting spinning. lustrates Class ;ferred to in this article for driv- 1223 Atlanta, Ga., STUART W, CRAMER, Charlotte, N, C» Mill Engineering:, Continued* Cramer Spinning Drive, Continued.
