A device for gripping and holding a substrate comprises at least two clamping parts (15, 17). The first clamping part (15) is arranged a distance apart from the second clamping part (17). First and second clamping parts (15, 17) are movable relative to each other along a longitudinal axis (20) so that they can grip and clamp a substrate (13) at opposite edges. In a preferred embodiment the clamping parts (15, 17) are formed by rollers. At least the rollers (17) are rotatable about an axis perpendicular to the plane of the substrate (13) to be gripped in order to allow a rotation of the substrate (13) when it is gripped. The device has the advantage that the substrate, when it is gripped, takes always a centered and well defined position.
