Method of cutting window covering

Abstract

A method of cutting a window covering includes providing a window covering cutting apparatus, and utilizing an input device thereof to receive a mounting mode, cutting size information and identification information of the window covering. A position detecting device detects a position of a limit assembly and generates a position detecting value correspondingly. A signal processing circuit generates adjusted position information and target position information according to received information and the position detecting value. A manual operating member is manually adjusted to move the limit assembly until the adjusted position information equals to the target position information. The signal processing circuit sets a cutting device to cut the window covering after it abuts against the limit assembly. The method obtains a correct cutting position of the window covering by calculation of the signal processing circuit, thereby reducing cutting errors in size of the window covering due to miscalculation by users.
