Abstract
A suction tube extends in parallel between the licker-in and the feed plate of the co-direction feed device while a supply duct extends from the fiber lap delivery point to the suction tube. The suction tube and duct serve to remove dirt by suction and extraction at the delivery point where the fiber lap is delivered to the licker-in. The supply duct extends tangentially into the suction tube in order to maintain the entrained dirt particles in a helical flow in the tube.
