The Klopp CR1 Coin Crimper, is a crimping machine to be used with both pre-crimped (shotgun shell) and (flat) style wrappers. Photo displayed is Model CR4, which includes four crimping heads and storage rack. This model, Model CR1, is equipped with one crimping head. The machine applies a tamper-proof rolled edge so coins can not be removed without evidence of wrapper theft. Insert the proper crimping head into the receiver, turn on power and place the open end of the pre-filled wrapper against the crimping head and lightly press until the wrapper is folded over (Approximately two seconds). Motor is a 1/30 hp, 115 volts, 60 cycles (220V optional).
