Abstract: The repainting head is designed to be installed on a workbench of a repainting machine for repairing circular lids. It is characterized in that it comprises a repainting device (1) moveable by means of an elevation device (2), this repainting device (1) having a main rotary shaft (13) to which are attached one/two axial shafts (18) on which are mounted one/two painting arms (19) that are constrained to rotate with the main rotary shaft (13). Each repainting arm (19) is connected to the respective painting gun (20), the distance of which from the geometric centre of the main rotary shaft (13) is variable, each arm (19) rotating about the axial shaft (18), the required position of each repainting arm (19) being set using anchoring means that prevent any relative movement between the main rotary shaft (13) and the axial shaft (18).
