Abstract
A loading strip (1) for supplying individual explosive powder charges in a setting tool is formed of an elongated belt-shaped member (2). The member has openings (2a) therethrough with a hollow receptacle (3) projecting outwardly at each opening from one surface of the member (2). The interior of the hollow receptacle (3) in combination with the corresponding opening (2a) form a space for holding an explosive powder charge. Annular gap (2b) encircles each opening (2a) and extends inwardly from the opposite side of the member from the receptacles. A bulge-like projection extends into the space formed by the receptacle and the member. The projection has a hollow recess (2c) located eccentrically relative to the opening and the hollow space and faces the opposite side of the member (2). An ignition medium (6) is placed in the hollow recess (2c). A base plate (7) forms a closure for the explosive powder charge space and the ignition medium hollow recess.
