This invention relates to improvements in bob
bin receivers for weft replenishing looms and it
is the general object of the invention to provide
a receiver which is reversible or can be turned
inside out to discharge bobbins therefrom.
In weft replenishing operations the spent or
exhausted bobbins are discharged downwardly
