This invention relates to a method and appa
ratus for the blending of fibers and more espe
cially to a plurality of fiber preparation machines
adapted to deliver certain quantities of iibers
into a common conveyor with means for auto
matically stopping each machine when a lprede
termined quantity of fibers has been processed
and holding the fibers ready for delivery position
and continuing operating the other vmachines
means for automatically removing from the con
tainers all of the retained fibers therein, when
the last of a plurality of interconnected machines
have processed its predetermined amount of fi
, bers, so that all of the various batches of ñbers
held in the various containers will be delivered
simultaneously to a suitable fiber processing ma
