Table III. — Test of willowing machine — Continued. 



Coir produced (kilograms) 473.1 



Power required: 



Kilowatts 2 



Horse power 2.7 



Time required to willow: Total, 13 hours, 41 minutes; per 

 husk, 17 seconds. 



The results recorded in Table III for the capacity of the wil- 

 lowing machine, like those of the crusher, are below those given 

 by the makers; the power consumption is slightly greater. 

 During this test the speed of the drive pulley was 308 revolutions 

 per minute, which is about 43 revolutions per minute higher 

 than recommended by the manufacturers, and it was so geared 

 that the beater shaft ran at 214 revolutions per minute and the 

 wire cage at about 5 revolutions per minute. Although the fiber 

 was thoroughly freed from all loosely adherent dust, dirt, and 

 short fibers, it was badly tangled as the result of having been 

 stirred by the beaters. 



The design of these machines should be improved, and they 

 should be made to operate with less noise.
