As shown in fig. 4 and 5, the wirecord fabric processing system of the present application includes a frame 50, and the below-described cord fabric trimming devices 60 are provided on both sides of the frame 50.

As shown in fig. 1 to 6, the curtain trimming device in the present application includes a mounting assembly 10, a positioning assembly 20, and a cutting assembly 30. The positioning component 20 is arranged on the mounting component 10, at least one part of the positioning component 20 can move relative to the mounting component 10, and the positioning component 20 is provided with a positioning channel for the curtain cloth to pass through; the cutting assembly 30 is provided on the mounting assembly 10, the cutting assembly 30 is located downstream of the positioning assembly 20 in the moving direction of the curtain and cuts the curtain passing through the positioning channel, and the cutting assembly 30 can cut the curtain from both sides in the thickness direction of the curtain.
