ABSTRACT:
A shedding device for a double-lift open-shed Jacquard loom which comprises a pair of vertically shiftable horizontal blades adapted to pass each other and cooperating with lifters which are provided with projection in opposite directions respectively engageable by the blades. The blades of each are provided with spaced apart lifter-engaging surfaces adapted to engage the respective projection upon upward movement but to deflect the lifter away upon downward movement past the projections. Between these spaced apart surfaces of the blades, the blades are incapable of engaging the lifters and the lifters can be shifted transversely to the blades to position them in line with an inclined engaging surface of the blade or in a region between such engaging surfaces.
