Majority of laboured workforce in our country is associated with farming
allied activities. Though our government provides economical subsidiaries
to the agricultural people, their safety in use of agricultural machinery
of productivity of the manual labour needs more prioritisation.
Jute farming supports millions of farmers and their families and is only
terms of its use and variety, after cotton. A natural and cheaply available
is completely biodegradable. The high tensile strength of jute had made
it the most
commonly used material for bulk packing purposes as your gunny bag.
The jute fibre is spun into yarn on a spinning machine that uses bobbins
the yarn. These bobbins are placed within flyers and reciprocate to facilitate
winding process. Besides winding the yarn, these flyers provide the required
to the yarn.
Prof. H. Hirani of Department of Mechanical Engineering invented a new
design of the jute spinning machine flyer to
reduce the risk for the operator. Their design suggests a new geometry
for the lateral extension in a flyer; such that due
the spinning movement and tension created, the yarn automatically slides
towards the inner section of the flyer. The
design can be operated at higher speeds providing extra strength to
the yarn. It is also advantageous economically to
use this geometry because the deformation of the flyer is reduced whereby
increasing its usage life. Problems associated
with the hairiness of the yarn are minimised and the flyer is labour-health
friendly with decreased noise levels.
This invention can form a stepping stone for our economy to increase
the productivity of our fast developing nation.
