Device for locating on and holding flat object, e.g. paper sheet

摘要

The device (1) has a clamp split into at least two paired opposing parts (2). Each has an inner clamping surface (11) with a wave shape. This shape may be a low amplitude sinusoid which may blend into a flat bearing surface (7) running axially along the clamp part. When the parts are put together, there is preferably little or no clearance between the crests (13) and troughs (17) of opposing parts. When the clamp is subject to a low compressive force, the part's free ends (14) contact.
