The present invention relates to an apparatus for manufacturing a paper cup with an improved structure of coupling mold assembly capable of making a side paper and a bottom paper of paper cup to more stably adhere to each other and manufacturing one paper cup for each one revolution of a rotation table. When a bottom paper supply unit (40) couples a bent part (12a) formed by bending an edge of a bottom paper (12) downward to a lower part of a cylindrical side paper (11), the bottom paper supply unit supplies so that the bent part (12a) is positioned at the height at least twice higher than the width (a) of the bent part (12a) of the bottom paper. Therefore, the apparatus for manufacturing a paper cup can reduce the failure rate of a paper cup by stably performing thermal adhering between the side paper and the bottom paper. |
