Abstract (en)

[origin: EP1375709A2] In an air spinning machine start-up process an elongated feed of fibres (10') is converted to yarn (11) in a finishing unit (28) with a powered inlet feed (29, 30) and a powered output (32). The assembly has a splicing station, an air vortex outlet (3) and a yarn withdrawal unit. After an interruption of the spinning process, the process is resumed by a number of defined steps. In the start-up process, the start-up of the inlet and outlet sections are staggered to provide an overlap at the splicing point (11). Following a break, the finishing unit is re-started and the fibre ends are separated by stopping the output section. The yarn end is reversed to a pre-determined point where it is exposed to the air vortex and then advanced to the splicing station.
