The Klopp CR1 crimper is equipped with one crimping head and is provided with a tamper proof rolled edge which prevents removal of coins. The device also consists of a storage rack for crimping heads. The machine is easy to use, lightweight and is also compact in size. Coin crimping doesn't take more than a couple of seconds and it can be done with both shotgun shell and flat style wrappers. The operation is as simple as it sounds, just insert the required style of crimping head and switch on the device while you place the open end of the wrapper against the crimping head.
