ABSTRACT:
Each of two crimping hooks for crimping projecting edges of a piece of wrapping paper wrapped around a coin stack in a coin package machine has an inner guide surface of a convolute shape designed to curl and crimp positively a respective projecting edge when pressed against that projecting edge, as the wrapping paper is rotated together with the coin stack, the edge thus crimped forming a bead by which the coin stack is tightly packaged in a stably rigid state.
