An apparatus for joining two ring-shaped members (12,13) in stacked relation is disclosed and comprises a jig (28), pressing means (50), drive means (60) and spot welding means (70). The pressing means (50) is configured for urging a first ring-shaped member (12) into contact with a second ring-shaped member (13) held by the jig (28) so that they can be rotated together by the drive means (60) and the spot welding means (70) is configured for tack-welding ring-shaped members (12,13) being rotated by the drive means (60). The apparatus is specifically intended for use in the manufacture of a device for counteracting the imbalance caused by the uneven distribution of laundry in a washing machine drum. <IMAGE> |
