Effects of Qperating Parameters of Non-Lap-Card-Feeder on Static Pressure and Air Velocity at Card Distributors

Abstract

The transportation of opened tufts in spinning processes is now generally carried out by the air flow between each station of blowing Processes, or between each station connecting blowing and carding processes.
The air shooting system through a duct has been developed to a satisfactory level in order to connect blowing and carding processes, is used in many factories in Japan.
In this report, static pressure and air velocity at each card distributor are investigated on various factors of aNon-Lap-Card Feeder.
And it became clear that the most influential factor on both static pressure and air velocity is the duct resistance in distributing uniform fiber masses or tufts to each card.
