Abstract
A method for tensioning unrolled donor substrate to facilitate transfer of organic material to form a layer on the unrolled donor substrate, comprising the steps of: delivering of a portion of the unrolled donor substrate from a roll to a frame disposed in an organic coating chamber, such frame defining an aperture; engaging the unrolled donor substrate and tensioning such material using a first clamp assembly associated with the frame; coating the tensioned donor substrate with an organic layer in the organic coating chamber; and cutting the unrolled tensioned portion of donor substrate into a sheet before or after it has been coated with organic material.
