A reinforced tube suitable for use in the construction of an explosive signal transmission device. The tube is constructed from a low yield strength plastic material into which has been deposited one or more reinforcing yarns of a high tenacity and low elongation material in a position substantially parallel to the axis of the tube during the extrusion process.

A reinforced fuse tube which resists longitudinal deformation comprising: (a) a wall comprised of a low yield strength plastic defining a passageway therethrough in which a reactive element may be placed, said tube having a diameter of about 0.3 inches or less; and (b) one or more reinforcement yarn

A reinforced fuse tube which resists longitudinal deformation comprising: (a) a wall comprised of a low yield strength plastic defining a passageway therethrough in which a reactive element may be placed, said tube having a diameter of about 0.3 inches or less; and (b) one or more reinforcement yarns of a high tenacity non-conductive material exhibiting less than 15% elongation at failure deposited within said wall, said reinforcement yarns being positioned substantially parallel to the longitudinal axis of said fuse tube, wherein the distance from the interior surface of said wall to the axis of the reinforcement yarn is equal to or less than 0.20 of the nominal thickness of the tube wall, said reinforced yarns fail when said fuse tube is elongated about 4% such failure causing a visible depression on the tube in the area of failure allowing the user to identify a defective tube.
