Abstract

A method for producing lightning bolts for tubular photography having a closed end by a pouring tip, in which the tip is formed by heating a part of the lamp tube and stretching it to form a thinning through which is later introduced a combustion activating gas in the lamp and then the discharge tip is closed by heat, characterized by the operations of: heating the tube of the lamp in the union of the bulb or bulb of the lamp with the thinning; allow the thinning to cool sufficiently so that it becomes sufficiently rigid so that it can maintain its shape while forcing the still hot, plastic interior parts of the contraction down into the bulb of the lamp; and causing the thinning and bulb of the lamp to move relative to each other to depress the central parts of the contraction and form a raised re-entrant rim that surrounds a retroverted cavity at the end of the bulb of the lamp.
