Abstract
A coating dispensing head includes a rotary dispensing device, a rotator for rotating the rotary dispensing device and a tachometer for generating a light signal in response to rotation of the rotator. The head includes a first connection for supplying the coating to the dispensing device, a second connection for supplying motive power to the rotator and a first optical fiber having a first end for receiving the light signal and a second end. At least one of the first and second connections includes first and second passageways terminating at respective first and second generally flat surfaces and connectors for holding the first and second surfaces against each other with the first and second passageways aligned so that the one of coating and motive power supplied to one of the first and second passageways flows into the other of the first and second passageways and thence to the one of the dispensing device and rotator. The second end of the first optical fiber conducts the light signal to one of the first and second surfaces. Third and fourth passageways are provided in the first and second surfaces. The connectors hold the first and second surfaces against each other with the t…
