Then, even after exiting the guide hole 9 of the guide cover 3, the spiral traveling state is maintained around the electric wire 6 for a certain distance. The spiral air after exiting the nozzle body 1 forms an air guide AG for the electric wire 6 as schematically shown in FIG. 6, and the electric wire 6 goes straight over a distance until the air guide AG disappears. To be guided. Of course, such an operation occurs both when the electric wire 6 is being fed out by the feeding roller pair 30 and when it is stopped.
For example, when the operation of the roller pair 30 is stopped, the electric wire 6
However, even in such a case, the linearity is maintained in the portion where the air guide AG is present, and chucking or the like is easy to perform, so that the next process is started. There will be no problems with.
