Here is a closer view of gobo wheel from a Mark-2 Standard TELESCAN. It's the first system of rotating gobos invented by Cameleon in 1989 from an idea of lighting designer Alain LONCHAMPT, wanted for a show of french singer Michel JONASZ, seeing the image of gobo turning on itself.
This idea, applied in technique and mechanicaly by Cameleon was the point of birth of this now classic feature on the moving lights over the world. Concretely, it's a system where the gobo is housed in a rotating cylinder (on ball bearing), which is driven by a distant motor, remote movement is transmitted via a chain and a gear assembly mounted around the same axis of the wheel.
With this system, rotating gobos is performed identically on the two rotating gobo wheel at the same time. They are engaged in the beam or not.
The system is managed in linear control on a specific gobo rotation channel. The angle of rotation in the left direction or the right, and gradually in terms of speed, then control is lower ( from 0 to 50 %) or above ( 50 to 100 % ) of the zero point for the rotation drive gobo.
