Conveying of filament bundles over long conveying sections

A process for conveying continuous fiber filaments from a first operational stage to a distant operational stage comprising the steps of initially introducing the fiber filaments into a first air injector at the front of a conveyor channel, pneumatically moving the fiber filaments through the first air injector and the conveyor channel by creating and maintaining an air flow stream through the channel, allowing the air flow stream to escape at spaced apart locations along the conveyor channel while injecting air into the channel at those locations in order to continue pneumatic movement of the filaments through the channel, mechanically guiding the fiber filaments within the conveyor channel, continuing to pneumatically convey and mechanically guide the fiber filaments through the conveyor channel until the filaments reach the distant operational stage, terminating the air flow stream when the filaments reach the distant operational stage, and pulling the filaments from the first operation stage to the distant operational stage through the coneyor channel, while continuing to mechanically guide the fiber filaments within the conveyor channel.
