An aspirator provides linear control over air flow for manipulation of extruded fibers. A distribution manifold has a barrel valve between first and second flow channels, enabling precise, linear control over air flowing from a charge conduit to a pressure chamber surrounding a discharge pipe. Plural orifices in the discharge pipe connect the pressure chamber to the interior thereof, which is configured as a Venturi tube. Discharge pipe surfaces that can contact filaments therein are of hardened material while non-contact surfaces are of lighter materials.

A yarn guide channel for arrangement between a spinning device and a winding device of a spinning machine producing a take-up package in which a yarn guide channel forms a passage channel for a yarn running between the spinning device and the winding device. The yarn guide channel has a plurality of pneumatically engageable channel sections coupled to each other, having at least a first channel section, a second channel section and a channel connection section disposed between the first and second channel sections, in which the channel connection section has a mouth for supplying compressed air into the yarn guide channel for generating a pneumatic overpressure in the first channel section associated with a pneumatic suction effect in the second channel section.

A process for operating an air-jet spinning device such that after a spinning interruption the yarn end of the spun yarn accumulated on a take-up package is picked up by a suction nozzle and transferred to a yarn end preparation device. The yarn end is processed in the yarn end preparation device and is then transferred to a first area of an outlet opening of the spinning cone, the yarn end is pneumatically transported to a second area of an inlet opening of the spinning cone and is positioned there within the air-jet spinning device at a distance in front of the inlet opening, the drafting system of the relevant workstation is raised and the sliver is conveyed through a sliver guide of the nozzle block into the second area of the inlet opening of the spinning cone and there spun onto the prepared yarn end of the spun yarn.

A proofing air jet having a hollow elongated body having an air outlet and a suction inlet, the air outlet opposing the suction inlet, a pressurized air inlet into the body between the air outlet and the suction inlet, the pressurized air inlet being angled with respect to the hollow elongated body to flow pressurized air in a direction from the pressurized air inlet to the air outlet and provide a suction at the suction inlet, the air outlet having an innerduct/microduct connector for connecting to an opening of the innerduct/microduct, and the suction inlet having a string inlet configured to accept string. A plurality of the proofing air jets can be connected to a manifold.

A method and apparatus for removing optic fibers from multiple spools of optic fiber involving one or more rotating trees on which spools of optic fiber are seated, a transport passage and a rotating carousel. The free end of a fiber is pulled through the passage and attached to the rotating carousel such that the rotation of the carousel removes the rest of the fiber from the spool(s). The passage can be equipped with one or more rollers to reduce the friction between the fibers and the passage. The carousel may feature retractable rails to facilitate removing the fibers. The passage may also feature a blower and/or a venturi that provides suction to facilitate the movement of one or more fibers through the passage. A reciprocating tracking unit can be used to spread the fibers onto the carousel.

Disclosed is a creel including a plurality of creel bobbins, a plurality of guiding tubes located at the lower end of the creel and a plurality of guiding tubes located at the upper end of the creel, wherein each guiding tube is arranged for receiving a wire from an individual creel bobbin, wherein the lower half of the creel bobbins are arranged to feed their wires to the guiding tubes at the upper end of the creel, while the upper half of the creel bobbins are arranged to feed their wires to the guiding tubes at the lower end of the creel.
