Further, prior know automatic narrow fabric
needle looms feed the weft thread continuously as the needle holding the weft
thread is reciprocated in and out of the shed during the weaving process.
However, consumption of the weft thread during weaving is not continuous. As
the needle swings into the shed, temporarily there is a great demand for
thread.
When the needle swings back
and while out of the shed the demand for weft thread is very low or
substantially none. Therefore, between the weft thread feed and the needle a
mechanism must be provided by which the weft thread is held with suitable
tension during such irregular consumption of the weft thread. Accordingly, it
will greatly facilitate the narrow fabric needle loom during thread process.
