Abstract
A spreading device (20) for spreading a fiber filament bundle (32) to form a flat fiber band (14) has at least one convexly bent spreading edge (80) that is movable. The convexly bent spreading edge has at least one direction component perpendicular to a longitudinal extension of the fiber filament bundle (32) to be spread relative to the convexly bent spreading edge. The fiber filament bundle is configured to be placed under tension onto the convexly bent spreading edge (80) and thereafter is configured to be moved again with the at least one direction component perpendicular to the fiber filament bundle (32) away from the fiber filament bundle to release the fiber filament bundle from the convexly bent spreading edge (80).
