A device for manufacturing a seamless hat comprises an assembling cutting device and a layer connecting device, wherein the assembling cutting device comprises an ultrasonic metal wheel, an ultrasonic metal platform, a feeding rubber wheel, and a feeding metal wheel; the ultrasonic metal wheel and the feeding rubber wheel are concentric and closed each other, a metal wheel is disposed at the bottom of the feeding rubber wheel, the ultrasonic metal platform is disposed at the bottom of the ultrasonic metal wheel, a top end of a cone peripheral surface of the ultrasonic metal wheel has a sharp edge and a platform portion, which is disposed at a side away from the rubber wheel. Accordingly, the seam allowance cut pieces of the hat may not be initially connected to the edge of the hat. And, the assembling cutting device simultaneously proceeds the ultrasonic connection of the seam allowance cut pieces and the cut to the residue of the cloth in order to uniform the connection so as to get more efficient.
