Abstract (en)
[origin: US5997955A] PCT No. PCT/FR96/01979 Sec. 371 Date Jul. 6, 1998 Sec. 102(e) Date Jul. 6, 1998 PCT Filed Dec. 11, 1996 PCT Pub. No. WO97/21793 PCT Pub. Date Jun. 19, 1997A process for the purpose of preparing the sheet for deep-drawing and/or protecting it against corrosion, wherein an aqueous solution of polyethoxylates of one or more lanolin derivatives is applied to the said surface, the said surface is dried to obtain a deposit in dry state, then at least one operation of oiling is performed on the deposit in dry state. This process makes it possible in particular to simplify the operations of deep-drawing: even after prolonged storage, it is not necessary to re-oil the treated sheet just before deep-drawing.
