The baxter flyer assembly is the main zone of a jute spinning frame where twisting of fibre assembly to yarn happens and finally the yarn is wounded in a container commonly known as bobbin. In Jute Industry 4 ¼” Slip Draft jute spinning frame is predominantly being used. For a 4 ¼” Slip draft jute spinning frame, present baxter flyer assembly weighs around 2250 g and the flyer weight varies from around 800 to 900 g, depending upon the manufacturer. Such heavy weight flyer assembly restricts the operating speed of present jute spinning machine up to 4000 rpm. Moreover, manual stopping of this flyer rotating at high momentum creates problem to the spinning machine operator.
In order to overcome above issues, prevailing design of the Baxter flyer assembly has been modified by IJIRA where there is opportunity of reducing the length of heavier steel body of the assembly (wharve part) and increasing the effective working area at lighter flyer part. With this development the weight of the single Baxter flyer assembly has been reduced by 150g or around 6.7%.
With the development of new Baxter flyer assembly by IJIRA along with the increased bobbin length, the yarn content per doff per bobbin has increased by 10% and as a result the doff time loss has been estimated to decrease by around 0.42% , thereby increasing spinning efficiency.
