Abstract: A precision slit of adjustable width in which each slit jaw is guided via at least two guide parallelograms lying opposite each other and in which a single setting member acting jointly on the guide parallelograms of one side and displaceable perpendicular to the direction of movement of the slit jaws is provided for the setting of slit width. In a preferred embodiment, the guide parallelograms are developed as spring parallelograms, an embodiment prepared monolithically from a plate of compliant material and having particular advantages.
