Abstract
A method for making an insulating apparatus and an insulating apparatus made from such method having an insulating pad made up of a plurality of layers of metal foil, wherein at least two of the layers are separated from each other such that there are gas spaces between the layers, and a support for supporting at least a portion of the insulating pad and attached to the insulating pad by resistance welding, whereby the plurality of layers of metal foil are compressed around the area of the weld.
Claims36
A method of making an insulating apparatus, comprising:
- providing an insulating pad comprising a plurality of layers of metal foil, wherein at least two of said layers are separated from each other by a spacing means for providing gas spaces between said layers;
- placing a portion of said insulating pad in a support, wherein said portion of said insulating pad is between two opposing faces of said support;
- and
- resistance welding the two opposing faces of said support directly together such that said plurality of layers of metal foil evaporate to attach said support to said insulating pad, whereby said plurality of layers are compressed around the area of the weld.

A method of making an insulating apparatus, comprising:
- providing an insulating pad having a first side and a second side, said insulating pad comprising a plurality of layers of metal foil, wherein at least two of said layers are separated from each other by spacing means for providing gas spaces between said layers;
- placing a first support over at least a portion of the first side of said insulating pad;
- placing a second support over at least a portion of the second side of said insulating pad;
- and
- resistance welding said first support and said second support directly together such that said plurality of layers of metal foil evaporate to attach said first support and said second support to said insulating pad, whereby said plurality of layers are compressed around the area of the weld.

An insulating apparatus, comprising:
- an insulating pad comprising a plurality of layers of metal foil, wherein at least two of said layers are separated from each other by a spacing means for providing gas spaces between said layers;
- a support having opposing faces for supporting at least a portion of said insulating pad;
- said support positioned with the opposing faces having the layers of metal foil therebetween and attached to said insulating pad by a portion of the opposing faces being resistance welded directly together without said plurality of layers of metal foil therebetween, whereby said plurality of layers are compressed around the area of the weld.
An insulating apparatus, comprising:
- an insulating pad comprising a plurality of layers of metal foil, wherein at least two of said layers are separated from each other by a spacing means for providing gas spaces between said layers;
- a first support for supporting at least a portion of said insulating pad;
- a second support for supporting at least a portion of said insulating pad;
- and
- said first support and said second support being positioned with the layers of metal foil therebetween and attached to said insulating pad by a portion of said first support and said second support being resistance welded directly together without said plurality of layers of metal foil therebetween, whereby said plurality of layers are compressed around the area of the weld.
