Abstract: Process and apparatus for the production of a fuse having a cavity extending axially within the explosive core and being provided with a lining. The process includes the steps of continuously producing a casing at the lower end of the feed hopper, introducing an explosive from the feed hopper into the casing, passing the lining through the feed hopper while continuously winding filaments therearound in a helical manner for centrally guiding the lining through the feed hopper, and continuously introducing the lining together with the explosive into the casing at the end of the feed hopper. The apparatus includes a draw-off mechanism arranged vertically above the feed hopper, and one or more supply bobbins for the filaments can be provided as well as a bobbin for a tracer thread.

Abstract: A fuze for use in firedamp and coal-dust endangered operations suitable for use in the longhole blasting technique which includes a hollow tube, an explosive core of desensitized explosive surrounding the hollow tube, a wound strip of plastic encasing the explosive core, a multiple-layer spun casing of fibers enclosing the wound plastic strip and an envelope of inert substances surrounding the multiple-layer spun casing. The envelope is, preferably, a mixture of a polymer and insert substances covered, respectively, by cellulose-base fibers, a wound strip of plastic, a multiple-layer spun envelope of fibers, and finally a waterproof outer shell of synthetic resin.
