The upper pressing roller 14 cooperates with the first transmission belt 11 to horizontally transfer the pre-ironed shaped fabric and spread it on the first transmission belt 11. When the shaped fabric is spread on the first transmission belt 11 and the second transmission belt 12, it can be synchronously transferred horizontally with the first transmission belt 11 and the second transmission belt 12 under the action of contact friction.

High-temperature steam can form a plurality of penetration points on the surface of the formed fabric through the radial holes 25, and the air holes 27 can blow dry gas to the fabric around each penetration point, so as to quickly evaporate the moisture on the surface of the fabric.
