<p>The invention relates to a stacking unit of slats on support half-ladders for the production of venetian blinds, comprising at least one group 2 for assembling on a slat a hook and a half-ladder with eyelets O. Such group is positioned laterally with respect to a longitudinal sliding axis X of the slats and comprises: - a matrix 11, 12 having a cavity 13 for a portion of rim and two apertures 14 and 15 of access to the cavity, between which a through aperture 16 is made; - a device 31 for applying hooks in correspondence with the first aperture 14; - a device 40 for guiding a half-ladder in correspondence with the through aperture 16, leaving an eyelet in correspondence with the through aperture 16; - a device 32 for closing the hook (G) in correspondence with the second aperture 15 of the matrix. The stacking unit comprises means 4, 5 for generating a relative movement between the slat and the matrix so that a hook anchored to the rim shifts along the cavity from said first aperture to the second 15 crossing the through aperture 16 engaging the eyelet. The hook is closed in correspondence with the second aperture 15.</p> |
