As successive weft replenishing operations of
the front end of the plate 40 should remain up
on the bar 19 the accumulating weight of the
bobbins will tip the back of the ?oor 40 down
wardly, causing it to become inclined and
eventually slide off the bar l9.

seen that changes and modi?cations may be
made therein by those skilled in the art with
