摘要
In the production of explosive or detonating cords which are covered with plastic, a preliminary cord, which contains the explosive substance, is guided through the opening of an extrusion nozzle and is injection molded with plastic. Measuring sensors in the supply duct for the plastic monitor the temperature and/or the pressure in the supply duct. If permissible limit values are exceeded, a die piece and a spindle sleeve of the arrangement are driven out from a stationary block in opposite directions. The spindle sleeve divided in the lengthwise direction is separated by auxiliary drives from the cord. A plug is withdrawn from the wall of the supply duct by means of a further auxiliary drive in order to relieve pressure stressing. In addition, the preliminary cord is withdrawn from the danger region by reversal arrangment. Furthermore, when the protection arrangment is in the release state an additional cooling takes place.
