Abstract

A magazine for cartridges ignitable by adiabatic compression is especially useful for stud driving or setting tools. The magazine has a plurality of cartridges made of synthetic resin and a magazine belt made of synthetic resin for connecting the plurality of cartridges together. The magazine belt forms bottom walls of the cartridges and in the region of each of the bottom walls is provided with an intentional separation zone. A primer wafer is provided on the magazine belt in the region of the bottom wall near the intentional separation zone. Each primer wafer in an area near the intentional separation zone is thinner than in the remaining zone surrounding the area.
