ABSTRACT:
The invention relates to a method and apparatus for providing a plurality of sequentially arranged edged contoured slats for use in a blind. A strip of material 10 is provided lengthwise into the slat making machine. It passes through a forming unit 6 where it is cambered, into an accumulator 8 where any excess is held, through a position encoder 12 and over a collision detector 14. Edge contours are then cut into the strip material if they are not already pre-provided. The positions of any edge contours are detected by a sensor 18 which provides relevant information to a CPU 40. On the basis of this information and other pre-provided information on the type of blind being made guide holes and notches and the ends of the slats are cut ensuring that the contouring and the guide holes and ends do not interfere with each other.
