ABSTRACT:
In a pneumatic system for supplying air-borne fibers to the vertical feed chutes of carding machines and the like, the fibers which collect in the lower, formation section of each chute, are adapted to be compacted by a volumetric air pump that is mounted in each chute to direct pulses of compressed air into the upper end of its formation section. The density of the column of fibers in this section is monitored by apparatus which senses the air pressure differential between the upper and lower ends, respectively, of the formation section, and which generates an electrical signal proportionate to the pressure differential. This signal controls the operation of the variable speed electric motors which drive the air pump and a feed roll, which draws fibers from the upper, surge section of the chute and feeds them downwardly to the formation section. Means is provided for interrupting the operation of the motors whenever the density of the column of fibers in the formation section exceeds predetermined high and low limits. The air pump can also be designed to compact the fibers in the surge section of the chute.
