Roller Conveyors--Noise Nuisance Elimination.

Legislation in the USA prohibiting machinery operation at noise levels above 85 phon has been responsible for the development of a noiseless conveyor with installed accumulating effect. The roller conveyor presented in the article differs from conventional continuous conveyors in so far as the rollers are driven individually by a crosswise running round belt on a common drive shaft. The conveyor can also be driven in curves by only one shaft with the aid of universal joints and without using any further motors.
