the fabric piece 15 is urged by the secondary airstream to travel back to the branch line 70 and be conveyed therethrough this safeguard prevents fabric pieces 15 from simply lingering within the main line 40a in a position beyond the branch line 70 and in severe instances from being misdirected to the incorrect destination further travel of the fabric piece 15 is best understood by reference to fig2 through 4 after the fabric piece 15 enters the desired branch line 70 it passes through the upstream conduit 72 and into the deposit nozzle 74 as can be seen in fig3 the airstream is drawn downwardly through the deposit nozzle 74 then upwardly within the lumen of the bifurcating section 76 and out the stem of the bifurcating section 76 into the downstream conduit 78 from there the airstream is then drawn through the open vacuum valve 79 into the common vacuum lines 82 and to the vacuum source 80 in contrast the fabric piece 15 has sufficient momentum exiting the outlet end 75 of the deposit nozzle 74 that it is unable to reverse its direction as the air flow does and thus travels directly into a predetermined receiving tube 94 of the receiving station 90 as noted above the deposit nozzle 74 is narrowed at its outlet end 75 relative to its upstream end in order to accelerate the fabric piece 15 exiting the outlet end 75 and thus provide.
