The pillow is automatically pressurized and impregnated with glue using the pressurized impregnation device located at the rear side of the adjustment device, and then transported to the second conveyor after completion; S400. The pillow is transported to the automatic cycle pressurizing device using the second conveyor; S500. The main pressure rotating roller and the front pressure conveying roller in the automatic circulation pressure device are rotated and driven upward, and are input from between the main pressure rotating roller and the front pressure conveying roller until they are output from between the front pressure conveying roller and the upper pressure conveying roller. Steps S400 to S500 are repeated multiple times until the set number of glue spreading times is completed.
