The same components as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted. FIG. 1 is a plan view of a material width changing device provided with a cutting and laminating device for carrying out a method of changing a material width in a conveying process of a strip material W of the present invention, and FIG. FIG. 4 is an explanatory view of a control method in a parallel state, wherein the material width changing device is a conveyor device 1 provided with a cutting device 2 such as a bias cutter for cutting a band-shaped material Wa into a predetermined width.
And a transport conveyor 5 having a bonding device 4 (splice device) that intersects with the conveyor device 1 in a direction orthogonal to the conveyor device and is connected to a winding device (not shown).

Between the conveyor device 1 and the transport conveyor 5, there is provided a transfer device 3 of a strip-shaped material, the amount of movement of which can be controlled via a control device 10, and the transfer device 3 is a conveyer device 1 The strip material Wa cut to a predetermined width by the cutting device 2 is sucked and held at a predetermined position of the conveyor 5, that is, in the present invention, the center line in the width direction of the strip material Wa is set to the center line P of the winding shaft. Convey and drop to the position that matches -P.
