By configuring the inclined surface to be a smooth surface in this way, the sheet-like material stretched by the flow of gas blown from the gas injection device is smoothly moved to both side edges (width direction side) and stretched. This makes it possible to more efficiently remove wrinkles generated in the direction along the drawing direction of the sheet-like fabric.

  In addition, when the sheet-like fabric is a fabric in which gas can flow from one side to the other side, such as a knitted fabric for clothes, the gas blown onto the sheet-like fabric A part of the sheet passes through the sheet-like cloth, enters between the opposed surfaces of the inclined surface and the sheet-like cloth, and flows toward both side edges (width direction side) of the sheet-like cloth. A gas flow that flows toward both side edges (width direction side) is formed on both sides of the sheet-like material. By configuring the inclined surface to be a smooth surface, the flow of gas flowing between the opposed surfaces of the inclined surface and the sheet-like fabric can be formed in a state with less disturbance such as vortices. Can be quickly and neatly extended to both side edges (width direction side) to remove wrinkles generated in the direction along the drawing direction of the sheet-like fabric.

Moreover, it is preferable that the said gas injection apparatus which injects gas toward the said sheet-like material | dough on the said inclined plate injects gas toward the said sheet-like material | dough vicinity of the upper end part of the said inclined plate. When the gas injection position by the gas injection device is set in this way, the gas can be injected to the sheet-like cloth whose degree of wrinkles has been reduced by receiving a gravity action or the like that extends downward on the inclined plate. Even if the flow rate of the injected gas is set low, soot can be efficiently removed.

Moreover, it is preferable that the said gas injection apparatus which injects gas toward the said sheet-like material | dough on the said inclined plate injects gas toward the said sheet-like material | dough vicinity of the upper end part of the said inclined plate. When the gas injection position by the gas injection device is set in this way, the gas can be injected to the sheet-like cloth whose degree of wrinkles has been reduced by receiving a gravity action or the like that extends downward on the inclined plate. Even if the flow rate of the injected gas is set low, soot can be efficiently removed.
