Abstract
The lints among those separated objects of this classificatory action by pneumatical force under the taker-in cylinder are consisted of the same staple diagramatically to the lints contained in the waste under the taker-in part. And those are nearly similar to the lints contained in the waste by the flat bar part. Hence, the classification with the length of fiber as that of cage cylinder are not performed, but that with the terminal velocity are performed. The terminal velocity of lints contained in the waste under the taker-in part are more than 0.6-0.65m/sec at least, so those lints are limited to those adhered to the immature fiber, part of seed, etc. or a few lints mixed in trashes, except the unsatisfactory opened lints. Therefore, the loss of lint in this part are relatively very small to another parts, the effective cleaning ratio is maximum, and the most effective cleaning action is performed in this cleaning mechanism of the experimental card. And the decrease of waste in this part is not desirable since the quantity of waste in this part are offsets each other with those of the flat part, but it is more important from the view point of proper cleaning effect to classify impurities possible as much as by maintaing the pneumatical action to convey the lints that have the terminal velocity slower than 0.6-0.65m/sec.
To improve the composite cleaning action of this experimental card is to improve the more effective classificatory action at taker-in cylinder part. And the operating condition of this card to obtain the maximum effective cleaning ratio, is to decrease the loss of lints by increasing the quantity of lap feed, and to improve the efficiency of cleaning by multiplying the revolution of taker-in cylinder as much as possible. In addition it is more desiable to have suitable width between undersheet and taker-in cylinder to have minimum suction force by the cage blower to convey those lints, and to maintain the slower revolution of cage cylinder lest it obstructs to transfer those lints to the cylinder.
