ABSTRACT:
A device for making a blind having Y-shaped pleats comprises an ultrasonic welding gear or a high frequency welding gear, a pressing wheel, a base plate, a motor, two drive wheels, two guide wheels, and two guide brackets. The welding gear has a weld head over which the pressing wheel is mounted for pressing a blind cloth against the weld head. The base plate is disposed horizontally between the pressing wheel and the weld head and provided with a through hole corresponding in location to the pressing wheel and the weld head. The motor is used to drive the pressing wheel which in turn drives the two drive wheels to press the blind cloth moving on the base plate. The two guide wheels are driven by the motor for guiding the unwelded blind cloth to move. The guide brackets are provided respectively with a protruded portion corresponding in level to the base plate for holding the pleats of the blind cloth waiting to be welded.
