Claim:
An apparatus for compensating an unbalance of a vehicle wheel by applying onto the wheel, at a determined compensation location on the wheel, a self-adhesive compensating weight having a determined length cut from a continuous weight strand, wherein said apparatus comprises: a program-controlled manipulator device including a movable working arm; and a balancing head mounted on said working arm, wherein said balancing head includes a weight strand feed device adapted to feed the continuous weight strand, a cut-off device adapted to cut the compensating weight having the determined length from the continuous weight strand, and a roll-on roller adapted to apply the compensating weight onto the wheel at the determined compensation location by rolling on said compensating weight; wherein said weight strand feed device comprises a feed channel having inner dimensions corresponding approximately to an outer width and thickness of the continuous weight strand so as to receive said continuous weight strand slidingly therein, and wherein said feed channel is configured and arranged to feed the continuous weight strand to said roll-on roller; and wherein said roll-on roller has a width corresponding approximately to the width of the continuous weight strand, and has an outer circumferential surface with a cylindrical or conical surface configuration; and further comprising a controlled rotation drive connected to and adapted to rotationally drive said roll-on roller.
