Abstract
A roll-to-roll press device includes an unreeling shaft, a pressing unit, a reeling shaft, and a tension controller. The unreeling shaft unreels substrate film reeled thereon. The pressing unit presses the substrate film to print microstructures on the substrate film. The reeling shaft reels the pressed substrate film thereon. The tension controller adjusts a tension of the substrate film according to a thickness of a coil of the substrate film on the reeling shaft.
Claims14
A roll-to-roll press device, comprising:
- an unreeling shaft for supporting a coil of a substrate film thereon and unreeling the substrate film supported thereon;
- a pressing unit for pressing the substrate film and to print microstructures on the substrate film;
- a winding shaft for winding the pressed substrate film thereon;
- a tension controller for adjusting tension of the pressed substrate film on the winding shaft according to a thickness of a coil of the substrate film wound around the winding shaft.
