Claim:
An apparatus for stabilizing and positioning single or multiple sheet articles, which are retained in the region of a first edge, and conveyed in a conveying direction along a conveying section, by a conveying arrangement, having a plurality of delimiting elements which can be introduced into the conveying stream, and moved along therewith, in a stabilizing portion of the conveying section, which comprises: a) at least one trailing delimiting element, which is capable of localizing the position of a second edge, which is located opposite the first edge, counter to the conveying direction; b) at least one leading delimiting element, which is capable of localizing the position of the second edge in the conveying direction, at least two receiving means for the second edge being formed, at least over the course of the stabilizing portion, between said at least one trailing delimiting element and said at least one leading delimiting element and between a respective leading delimiting element and a respective trailing delimiting element which follows the latter in the conveying direction; c) at least one further delimiting element, which is capable of localizing the position of the second edge in and/or counter to the conveying direction; d) a drive arrangement for moving the leading and trailing delimiting elements along a continuous circulatory path; e) a drive arrangement for moving the further delimiting element, f) the delimiting elements being formed and driven such that the second edge passes only into a receiving means and not into the intermediate region between the at least two receiving means; and g) a cam wheel with at least one cam which is arranged in a rotatable manner at the beginning of the stabilizing portion, the further delimiting element being formed by the at least one cam.
