Best Solutions For Your Expects!


Kobayashi Engineering Works, Ltd. had been manufacturing drum cutters for the paper industry, and in the late 70s. The Rotary Oscillating Cutter (Patent No. 1162726) was developed based on a new idea. We have delivered 40 Rotary Oscillating Cutters mainly for sensitized film industry and aluminum industry. At the same time we developed Double Rotary Drum Cutter that attained high speed running, with keeping the high accuracy. We have delivered about 50 Double Rotary Drum Cutters mainly for board paper, steel plate and aluminum plate.
