Abstract
Methods and apparatus are described for removing donor sheets from substrates. A take-up roller contacts the donor element at or near an edge thereof and a peel roller contacts the donor element at a location spaced apart from the edge. A securing mechanism secures the edge of the donor element to the take-up roller which is then moved away from the substrate. While maintaining the peel roller in contact with the donor element, the take-up roller is rotated to take up the donor element while the peel roller and take-up roller are both simultaneously moved in a direction tangential to the substrate. In this manner, the donor element is peeled from the surface of the substrate.
