In the emerging fields related to healthcare, energy, and environment, realization of devices on flexible sheets is imminent. The materialization of such sheets would require fabrication of parts of devices on a fiber substrate where they can be assembled and interconnected by weaving. To broaden the area of a flexible sheet device, larger number of such devices will need to be formed directly on the fibers. Moreover, fabrication cost of a flexible sheet device, larger number of such devices will have to be addressed in order to make large size fabric manufacturable at affordable price. Therefore, a high-speed, low-cost, environmental friendly batch-manufacturing process of the devices on fiber is required. In this paper, we developed a reel-to-reel thermal imprint system combined with a sliding roller imprint mechanism. In this process, fiber substrate is sandwiched by a couple of flat molds, and these molds slide opposite direction each other under suitable press force and temperature. And then, we optimized conditions of this imprint process. Finally, we succeeded to imprint continuously more than 100 times and to fabricate 1.6 m long imprinted fiber. And we succeeded to imprint almost on entire cylindrical surface. A stable imprinted region was about 160° at each side.
