Abstract
This invention provides an aspirator apparatus for the in line string up of a rapidly advancing filament from a continuous forming operation onto a rotating winding wheel. A top aspirator plate is disposed opposite and in facing relation to a bottom plate and is movable relative thereto. An actuator mechanism selectively moves the top plate in a direction normal to the bottom plate to adjust the separation distance therebetween and to selectively delimit an aspiration zone between the top and bottom plates. This aspiration zone has at least one aspirator inlet portion to receive filament, an aspirator outlet portion to exit the filament and an aspirator jet portion to capture, tension and direct the filament. A fluid jet means communicates with the jet portion to provide an aspirating jet of pressurized fluid therein, and a transport means moves the apparatus to effect filament string-up.
