ABSTRACT:
A flap is disposed across the opening between an expansion chamber and an exhaust air duct to control the delivery of fiber tuft-laden air into a feed chute or chamber. The flap has two wings which pivot about a common pivot axis whereby as one wing increases the flow cross section from the expansion chamber, the other wing reduces the flow cross section. A pressure difference produces forces on both wings simultaneously.
