Abstract
Abstract A riveter for setting blind rivets including a magazine which feeds the rivets into the riveter and conducts the sheared mandrels to a central collecting point. The riveter includes moveable guide jaws as well as moveable breaking jaws to substantially reduce the size of the tool for use in a wide variety of field situations. The magazine, which is automatically advanced through the riveter, exits therefrom in an empty condition and is ready for disposal or reloading and reuse.
