PROBLEM TO BE SOLVED: To keep differences in tension as slight as possible when a fiber band is severed.SOLUTION: This device (1) and a method are for producing monoaxial or multiaxial scrim from the fiber band. The device (1) comprises: a dispensing unit (7) for dispensing the fiber bands (6); a severing unit (9) for cutting the fiber bands (6) to a predetermined length; conveyor mechanisms (2, 3) for conveying at least one layer of the juxtaposed fiber bands (6) to a bonding mechanism; and a transport mechanism for depositing the cut fiber bands onto the conveyor mechanisms (2, 3). The severing unit (9) comprises a knife (10) with a cutting edge (12). The cutting edge (12) is displaceable in a direction of an extension of the cutting edge.
