Abstract
A lining for a hollow charge is formed by making impressions into a plate to form a multiplicity of impressions in longitudinally extending and transversely extending rows. The impressions of at least some of the rows are made into geometrical form, such as, hexagons or rectangles, with geometrical impressions or forms therein having center axes which are offset in adjacent rows. In one embodiment, the center axes of the geometrical forms of some rows are located along an imaginary projection line and those of other rows are arranged along an imaginary projection line which is at an angle to the first line, preferably, the separate lines being arranged on each side of a radial line and defining an angle with the radial line which has a ratio with the radial sector between adjacent radial lines between the two imaginary lines which is in the ratio of 1 : 2. The impressions may be rectangular in nature and the centers of alternate rows aligned along a radial line which makes an angle with an imaginary line containing the centers of the other rows. The overall configuration of the impressions may be rectangular, hexagonal, etc.
