Abstract
Abstract A method for mass producing and loading explosive charges in detonators, ds, relays, primers, etc., utilizing the explosive charges each in sheet form. Sheets corresponding to the various increments, each containing the finely divided high explosive and binder therefor, are superposed in the proper order preferably on a sheet of closing disc material, and the resulting structure of layered sheets is cored to produce the explosive train. The coring can be accomplished with a battery of cutters so that large numbers of explosive trains can be cut to size simultaneously. The explosive train cores thus obtained can be pushed out of the cutters into cups, which are then crimped and sealed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
68 words
A method for producing at least one explosive train which comprises superposing a. a first layer of sheet explosive comprising finely divided particles of an ignition explosive and a binder therefor; and b. a second layer sheet explosive comprising finely divided particles of a primary explosive and a binder therefor; coring the resulting structure of superposed sheets and ejecting said core of explosive train into a cup container.
Claim 2
Independent Claim
68 words
A method for producing at least one explosive train which comprises superposing a. a first layer of sheet explosive comprising finely divided particles of an ignition explosive and a binder therefor; and b. a second layer sheet explosive comprising finely divided particles of a primary explosive and a binder therefor; coring the resulting structure of superposed sheets and ejecting said core of explosive train into a cup container.
Claim 3
Dependent Claim
31 words
The method of claim 1, wherein a third layer of sheet explosive, comprising finely divided particles of a secondary high explosive and a binder therefor, is superposed on said second layer.
Claim 4
Dependent Claim
20 words
The method of claim 1, wherein the structure of superposed sheets is cored simultaneously with a plurality of core cutters.
Claim 5
Dependent Claim
76 words
The method of claim 1, wherein a sheet of closing disc material is superposed on the last layer of sheet explosive in the explosive train, after which the resulting structure is cored, and the cored explosive train is ejected into a cup container so that the layer of ignition sheet explosive is adjacent to the closed end of the cup container and the closing disc material is adjacent to the open end of the cup container.
