An improvement of the conventional method of wrapping cryogenic insulation around an inner tank disposable within an outer tank of a cryogenic tank system, where cryogenic insulation paper is unrolled from a roll thereof, wrapping the paper in serially disposed wraps around the inner tank, unrolling cryogenic insulating metal foil from a roll thereof and wrapping the foil in serially disposed wraps onto respective serial wraps of the paper. In the improvement there is provided at least one combined roll of cryogenic insulation having alternating combined layers of the paper of a defined first width and foil of a defined second width wherein the defined second width is less than the defined first width and the foil is centered on the paper so as to provide edge portions at each edge of the paper which are not contacted by the foil. Lengths of combined layers are unrolled from the combined roll, and the lengths of combined layers are serially wrapped around the inner tank.
A method of producing a combined roll of cryogenic insulation having alternating layers of thermal cryogenic insulation paper of a defined first width and thermal cryogenic insulating metal foil of a defined second width which is less than the defined first width and the foil being centered on the paper so as to provide edge portions at each edge of the paper which are not contacted by the foil, comprising the steps of:
An apparatus for producing a combined roll of cryogenic insulation having alternating layers of thermal cryogenic insulation paper of a defined first width and thermal cryogenic insulating metal foil of a defined second width which is less than the defined first width and the foil being centered on the paper so as to provide edge portions at each edge of the paper which are not contacted by the foil, comprising:
