Thesecond servo motor 32 drives thegear 34 which is connected to thegear 14 of the trans-roller unit 1 via thetoothed belt 27. Thegear 34 drives thegear 14 of the trans-roller unit 1 and the direction of the power is changed via theactive bevel gear 13 and thepassive bevel gear 12. Themetal line 5 is then transported by therollers 11 of the trans-roller unit 1. - The trans-roller unit1 is located between the
shaft 4 and theoutput shaft 61 so that the trans-roller unit 1 is rotated together with theshaft 4 and theoutput shaft 61. The trans-roller unit 1 has a box-like body in which turning mechanism is received which includes a shaft extending in the body and is connected to anactive bevel gear 13. The trans-roller unit 1 may have one set of a top and a bottom roller, or two sets of the top and bottom roller. This embodiment employs two sets of the top roller and bottom roller. An other shaft is located in the body and connected to apassive bevel gear 12 which is engaged with afirst gear 15 and asecond gear 16. Thefirst gear 15 and thesecond gear 16 are cooperated with each other, and thepassive bevel gear 12 is engaged with theactive bevel gear 13. Theroller 11 has a groove so that themetal line 5 is engaged with the two aligned grooves of thetop roller 11 and thebottom roller 11. - The
metal line 5 is clamped between the top andbottom roller 11 after it extends through thepassage 31 of theshaft 4. Themetal line 5 extends through theshaft 61 and thedisk 6.

Theco-axial gear 121 is rotated with thepassive gear 12 and drives thefirst gear 15 and thesecond gear 16. Therefore, themetal line 5 is moved by therollers 11 toward thedisk 6. When themetal line 5 is to be curled, by the computer, thefirst servo motor 21 drives theoutput member 22 and theshaft 4 and theoutput shaft 61 of the trans-roller unit 1 are rotated. In other words, themetal line 5 can be curled while still be fed toward thedisk 6. - Another embodiment of the present invention is shown in FIG. 5 wherein the
first servo motor 21 of the curlingdevice 2 is connected to theshaft 4 and thestator 211 is fixed to the base 7, and therotor 212 is connected to theshaft 4 by the output member as the previous embodiment.
