ABSTRACT:
Disclosed is an apparatus for cutting blind slats, including a conveying device for sequentially conveying a slat material and a cutting device turned on and off in synchronism with the conveyance of the slat material so as to form slats of a desired length, wherein the improvement is characterized by comprising: an input device having means for entering the length of a slat; a control device for converting the output signal of the input device to pulse signals corresponding to the slat length entered and outputting them; and a motor rotated on the basis of the pulse signals output from the control device so as to convey the slat material by predetermined lengths.
