Dobby capable of forming double cloth fells

The invention relates to a dobby capable of forming double cloth fells. The dobby comprises an input rotating shaft, a homodromous rotating shaft, a reverse rotating shaft, an output rotating shaft and a plurality of transmission assemblies, wherein the homodromous rotating shaft and the reverse rotating shaft rotate homodromously and reversely with the input rotating shaft respectively. Each transmission assembly is driven by the input rotating shaft, the homodromous rotating shaft or the reverse rotating shaft to drive a heald frame of a heald frame mechanism to move to one of an upper position, a middle position and a lower position, so that all heald frames can be located in the upper position, the middle position and the lower position through the dobby; and warp yarns penetrating through the heald frames can form the double cloth fells to achieve a diversified weaving effect. 种可形成双织口的多臂机,包含输入转轴、分别同向及反向于该输入转轴转动的同向转轴与反向转轴、及输出转轴，以及多个传动总成。每传动总成受到该输入、同向、或反向转轴带动，而连动综框机构的综框移动至上、中、下三个位置其中者，借此，所有综框均能利用该多臂机分别位于上、
