Then, the material is moved by the material moving mechanism, so that the material is reliably abutted against the replacement reference plane and positioned parallel to the center line.

According to a third aspect of the present invention, in the material width shifting apparatus according to the second aspect, the material moving mechanism is arranged such that the material moving mechanism is arranged on the upper surface of the material replacement arm toward the replacement reference surface. It is characterized in that a descending inclination angle is provided, a slider slidable in the length direction on the upper surface of the material replacement arm is provided, and the slider is constantly urged in a direction opposite to the direction of the replacement reference surface. It is assumed that.

Therefore, when the material is lifted by the material changing arm, the slider lowers the inclination angle of the upper surface of the material changing arm against the urging force in the direction opposite to the direction of the replacement reference surface due to the weight of the material. Thus, the material is reliably positioned against the replacement reference plane and positioned parallel to the wick. When the material is removed from the material changing arm, the slider is returned to the original position by the urging force.

And a pressing drive means for reciprocating the engaging member in the length direction of the material changing arm.

Therefore, after the material is lifted by the material replacement arm, the engaging member is moved toward the replacement reference surface by the operation of the pressing drive means, so that the material is pressed by the engaging member and is reliably replaced. It is abutted against a reference plane and positioned parallel to the centerline.

According to a fifth aspect of the present invention, there is provided a material width shifting apparatus according to the second aspect, wherein the material moving mechanism extends along a length direction of the material replacement arm. Is provided so as to be rotatable so as to incline the material of the material exchange arm toward the exchange reference surface.

Therefore, when the movable arm is rotated after the material is lifted by the material replacement arm, the material descends along the movable arm inclined in the direction of descending toward the replacement reference surface, and is reliably assured. It is abutted against the replacement reference plane and positioned parallel to the centerline.

According to a sixth aspect of the present invention, in the material width shifting apparatus according to the second aspect, the material moving mechanism is arranged such that the material moving mechanism is provided on the upper surface of the material replacement arm toward the replacement reference surface. A sliding member is provided on the upper surface of the material replacement arm to provide a descending inclination angle and to reduce frictional resistance with the material.
