Klopp and Semacon electric crimpers provide secure and fast crimping of coin tube packaging ends. These electric coin crimpers fold over the ends in a tight wrap that will not allow coins to be removed without being noticed. These crimpers work with pre-crimped shot gun style tubes or flat wrapper packaging. Each machine works with penny, nickle, dime, quarter, half dollor or dollar coin tubes. Simply attach the correct coin head, fill the tube with coins and gently press the tube into the head to get a perfectly crimped end.
