As a result, the separation of one heald H can be reliably performed, and in this case, the inclined suction surface 10a of the negative pressure suction member 10 has a heald hole H ₂ formed below the heald H. A plurality of suction holes 10b, 10b capable of sucking and holding the front surface of the heald H at the upper and lower positions
Since the front surface of the front heald H is securely held by suction, the separation gap R is surely provided between the lower portion of the front heald H and the elastically restored next row heald H.
The heald H can be satisfactorily separated from the heald H, and in this case, the extruded surface portion 6a for extruding the heald H in the front row laterally onto the extruded member 6.
Further, since the separation claw portion 6b to be inserted into the separation gap R is formed prior to the start of the extrusion by the extrusion surface portion 6a, it is possible to more reliably push out only one heald H, and the separation of the heald H by that much. Work can be carried out smoothly.

A separation gap is formed between the lower heald of the front row and the heddle of the next row elastically restored by adsorbing and holding in an inclined shape on the inclined adsorbing surface and releasing the pressing of the pressing member after the adsorbing and holding. To form Since the frontmost healds are pushed out laterally by the extruding member in the state where the separation gap is formed, only the frontmost healds can be reliably pushed out and the thickness of the healds or healds with warpage or bending exists. Can be dealt with, and the reliability, smoothness, and flexibility of the heald separation can be increased accordingly.
