Abstract:
An arrangement for automatic bow correction for use in a venetian blind assembly machine, the arrangement including;a slat profiling unit having an upstream end and a downstream end, the slat profiling unit being adapted to profile slat material fed thereto from the upstream end to remove pre-existing bow in said slat material and create a transverse curvature into the slat material exiting the slat profiling unit from its downstream end, the slat profiling unit comprising a leveling section downstream of its upstream end and a forming section downstream of the leveling section, the forming section providing a coarse adjustment for removing bow and the leveling section providing fine adjustment for removing bow; a control system for controlling the removal of said bow by automatically adjusting said leveling and forming sections of said slat profiling unit; and an accumulator station having therein means for optical measurement of bow in said slat material downstream from said leveling and forming sections and for providing a signal to the control system to govern the automatic adjustment of said leveling and forming sections.
