System and method for actuating a treatment device

A treatment device support assembly for actuating a plurality of treatment devices relative to each other for treating an article surface of an article, comprising:

• a plurality of device actuation systems, each configured to interconnect an adjacent pair of treatment devices, each device actuation system including:
• a gear system couplable to each treatment device of the adjacent pair of treatment devices, the gear system of each treatment device including:
• a first drive gear rotatably mountable to the treatment device;
• a coupler rail slidably mountable to the treatment device;
• a second drive gear rotatably mountable to the coupler rail;
• a coupler gear rotatably mountable to the treatment device and engageable with the coupler rail;
• a drive rail configured to interconnect the adjacent pair of treatment devices, and locatable between the first drive gear and the second drive gear of each treatment device of the adjacent pair of treatment devices;
• wherein, for each treatment device of the adjacent pair of treatment devices:
• the coupler gear is rotatable to move the coupler rail in a manner maintaining the second drive gear in continuous engagement with the drive rail against the first drive gear;
• and
• the first drive gear and the second drive gear are rotatable in a manner causing at least one of translation and rotation of the treatment device relative to the drive rail.
