Abstract
In an apparatus and a method for synchronizing a roll-to-roll transfer device, the apparatus includes a thin-film, a first roller, a second roller, a first load sensing element and a control part. The thin-film is transferred by the roll-to-roll transfer device. The first roller makes contact with a lower surface of the thin-film, and rotates with a rotational axis via a first rotational element. The second roller is disposed over the first roller, makes contact with an upper surface of the thin-film, and rotates with the rotational axis via a second rotational element. The first load sensing element senses a load of the first roller or a load of the second roller. The control part synchronizes a translational velocity of the first rotational element or the second rotational element based on the load sensed by the first load sensing element.
