Described herein is a device for forming the girdle in metal cages for tops of bottles for sparkling drinks, in which the cage (10) to which the girdle is to be applied proceeds along a production line withheld by a conveying cup (23); the device comprises a spindle (17), which sets itself facing said conveying cup (23); the spindle is provided with jaw means (25), which are designed to create with the spindle a substantially circular seat (20) for passage of the wire (16) for forming the girdle (14), and radial grooves (19, 31) that traverse said seat for housing the eyelets (13) of the cage that are to be traversed by said wire (16); the jaws are mobile between:
- a first open position, designed to receive in the radial grooves (19, 31) the eyelets (13) of the cage, which is pushed partially outside of the cup (23) on the spindle;
- a closed position, in which the jaws form with the spindle (17) said circular seat (20) and said oblique grooves (19, 31) to form the girdle by feeding wire from outside along said seat; and
- a second open position, in which the cage (10) is slid off the spindle (17) and repositioned on the cup (23).
