摘要
The foil supply strip is rolled in several passes and the last simple pass is followed by a double rolling pass where the doubled foil is wound and then separated. At the double rolling pass the foils are temporarily stored doubled as foil stacks and to produce further thicknesses part of the doubled foils is subjected to a further double rolling pass where the double foils are separated directly in front of the double rolling pass and a quantity of oil is sprayed in between the foils which is sufficient to allow a quantity of oil to emerge continuously in the rolling gap on both sides of the doubled foils. Independent claim describes apparatus with one or more quarto rolling members with unwinder (1a), trimmer and rolling brake (6) on inlet side and winder (9) and smoothing roller (8) on outlet side, as well as with separator and spray mechanism (2).
