Abstract (en)
[origin: WO2007149080A1] Devices and methods for conveying fibers are disclosed. According to the invention, fibers (1) are conveyed through a conduit (2) using a plurality of in-line flow amplifiers (6, 7, 8, 9) . In this manner, the crimped material may be transported along steep gradients with significantly smaller changes in bulk properties when compared with conventional transport mechanisms that merely pull the crimped material along the line of travel.
