product consisting of several bands What we claim is: I 1. The method of producing aluminium foils in band form, which comprises lubricatmg the surfaces of superposed bands of aluminium, removing the excess of lubricant by washing the bands with a, solvent, repeatedly subjecting the superposed strips to a rolling operation at a slight pressure while the strips are under tension to a thickness less than 0.0008 inch, and annealing the bands at-intervals during the rolling operation. p
2. The method of foils in band form, eating the surfaces of superposed bands of aluminium, removing theexcess of lubricant by washing the bands with benzin, repeatedly subjecting the superposed strips to a rolling operation at a slight pressure while the strips are under tension to a thickness less than 0.0008 inch, and annealing the bands at intervals during the rolling operation.
Intestimony that we claim the foregoing as our invention, we have signed our name in presence of twosubscribing witnesses.
