摘要
The invention relates to the clustering of firework bombs, employing for this purpose a device comprising a base plate (1) provided with cells (20) each of which is capable of receiving a free end (10) of a wick (9) and, in the case of one of them, a free end (57) of an igniter cord (58). Between two consecutive cells (20) a channel (33) is arranged, in the base plate (1), capable of receiving a pyrotechnic delay (3) ensuring the transmission of firing between the cells (20). Means forming a lid (2) retain on the base plate (1) the free ends (10, 57) of the wicks (9) and of the igniter cord (58) and the pyrotechnic delays (3). The clustering operation is made easier thereby and its result is made more reliable thereby. Changes in delay on firing ranges are made considerably easier. IMAGE
