<p>The invention concerns a unit for stacking slats on a support ladder with double crossbeams for the production of venetian blinds. The unit 1 comprises a device 20 for guiding a ladder on a positioning plane (m) and means 40 for divaricating at least one pair of crossbeams T1, T2 of such ladder S. The guiding device and the divaricator means are arranged along a longitudinal axis X along which the slats L are inserted. The divaricator means comprise a laminar element 41, movable parallel to the axis X between an advanced position, wherein it crosses the positioning plane at least with a front penetration portion 42, and a rearward position, wherein it does not cross such plane. The divaricator means comprise two divaricator tabs 51, 52 associated with the laminar element and arranged in correspondence to the front portion in opposite positions with respect to the axis X. Each tab is movable between a lowered position, wherein it is substantially parallel with the laminar element, and a raised position, wherein it forms an angle (a) with the laminar element.</p> |
