A drawing device containing a negative dobby is characterized by containing a simple shed regulating device, not needing to be installed on height of the negative dobby because the shed regulating device is offset on height of one of return levers capable of being closer than negative dobby elements and using a mobile stirrup element to regulate easily a shed. A stirrup unit is capable of avoiding vibrational motion of a flexible unit within range of width because the stirrup unit contacts and receives a part of the flexible unit. A weaving loom equipped with the drawing device has reliability and is inexpensive. A drawing device containing a negative dobby(10) comprises: flexible elements(30-33) connected direct with shaking levers(11,11') having fixed amplitude and connected with one of return levers(40,50) with a method capable of regulating; the shaking levers installed a double swinging lever(14) formed a hook(15) interlocked selectively with a readout system(20) of the negative dobby for a time that the shaking levers are fixed in moment; and a stirrup unit(415) installed on the return lever connected with the flexible elements, moved to the return lever and fixed with the flexible elements. The stirrup unit contacts and receives a part of the flexible elements. Distance(d) from a pivot axis of the return lever to the flexible unit becomes variable. |
