Coin crimper

A coin crimper for curling open end edges of packages with coins packed therein, said crimper including a package receiving opening, curling means for curling the open end edges of the packages inserted in said opening and driving means for rotatively driving said curling means, said coin crimper comprising package receiving opening diameter changing means for changing a diameter of said package receiving opening depending upon kinds of coins and hence packages of the coins, and curling position changing means for changing a curling position where the open end edges of the packages are curled depending upon the coins, thereby enabling packages of coins having different diameters to be curled by the single coin crimper, said package receiving opening diameter changing means comprising a plurality of pressure cores forming at their insides a substantially circular opening for receiving said open ends of the packages, each of said pressure cores being supported by a rockable arm and having a roller, said rockable arm being pivotally supported relative to the crimper and urged in one direction by spring means and a cam plate rotatable about said package receiving opening and fixed at predetermined positions and having inner peripheral cam surfaces each contacting said roller of said pressure core, thereby changing a diameter of said circular opening formed by said pressure cores when said cam plate is rotated to move said pressure cores into positions determined by said inner peripheral cam surfaces of the cam plate and said rollers of said pressure cores.
