path when said pocket is in the rear position
thereof but located forwardly of said path when
said pocket is in the forward position thereof, said
receiver unit having a part slidable into and out
of said pocket in a direction having a vertical
component, and stop means preventing said part
from moving upwardly out of said pocket when
the latter is in the rear position thereof but so
located that said part can move upwardly out of
said pocket when the latter is in the front posi

11. In a weft replenishing loom from which
depleted bobbins are discharged, a carrier hav

of said pocket, said stop overhanging said foot
when the pocket is in the normal position there
