In the rollermill used in the industrial field, the worker does not stop the roll and often carries out supplies of sheets and cleaning of the roll. Safety measures by fence or enclosure were difficult for such works, as the worker approaches the rollermill very closely. A new safety system with the floating function was developed in this study to solve these problems. It permits the running of the roll only when the blinded light beam number is less than the set number, and the roll stops when the condition except for it. The safe work became possible not only in automatic operation but also supplies of sheets and cleaning of the roll. It also realized the fail-safe floating control equipment, fail-safe rotational speed monitor and fail-safe safety distance monitor by the diversity controller with the self-checking function. Experimental results are described as follows ; 1) The smallest detection diameter M was expressed by M=bF+φ_M, where F is the floating light beam number, b is the interval of the optic axis and φ_M is the physical resolution of the photo-electric sensor. 2) The detection of the human body was possible when the sheet was bent or the human body was hidden in the blind area of hand tool.
