Abstract (en)
[origin: EP2767625A1] The spinning station (1) has a spinning nozzle (5) with a housing (6), a yarn formation element (7) and a nozzle inner space (20). The spinning nozzle is provided for supplying fiber composite (2) to a pair of delivery roller (4). The vortex flow is generated through pressurized air injection (13) by the yarn formation element, such that a yarn (3) is formed from the fiber composite. A metering pump (18) is provided for conveying an additive supply with a dosage containing dosage of additive into a compressed air supply line (11) for a compressed air feed circuit (12). An independent claim is included for a method for supplying additive into compressed air feed circuit of spinning nozzle at spinning location of air jet spinning machine.
