  • Method of manufacture of down insulated goods
    Patent number: RE29059
    Abstract: A method of manufacturing insulated goods with down filling, which comprises initially forming packets of a predetermined amount of down compressed into a predetermined size, which packets are placed in compartments for down in the goods. The compartments are completely closed for containing down, and the packet of down in each compartment is then ruptured by striking it, permitting the down to release into the compartment. Subsequent immersion of the down insulated goods in a solvent for the packet material dissolves such material leaving only down in the compartment.
