Apparatus, for positioning a venetian blind ladder cord (or the like) and for guiding the slats of a venetian blind between individual rungs of a multiple cord cross-rung, is described. Specifically, this apparatus applies a force to a rung of a non-active cross-rung in a direction opposite to that in which the ladder cord advances and provides an abutment surface that engages with the bottom surface of an interlaced slat in order to support the slat form below. This, in turn, holds the active cross-rung in a fixed position against the force urging the rung downward and thus advantageously maximizes the opening (target) between the individual rungs of the active cross-rung. Furthermore, this abutment surface resiliently moves in a substantially perpendicular direction transverse to the direction in which the ladder cord advances so as to readily permit an assembled slat to advance, while advantageously reducing the likelihood that a heavy slat load will be dumped.
