FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy, namely, to production of aluminium foil and winding it on spool in rolling. Foil is rolled with front tensioning and coiling onto detachable spool fitted on cantilever mandrel coiler. Note here that proposed spool has wall thickness defined from formula enclosed therewith. Spools are made from material with yield point exceeding that of rolled foil material.
EFFECT: reduced consumption of spools, lower spool and products costs.
