Abstract (en)
[origin: EP1985437A2] A forming method for materials in sheet form, particularly papery materials, characterised in that after laying a sheet of material extensible to at least 5% on a mould cavity, the sheet is subjected to at least partial stretching within the mould, while at the same time being retained along the edge of said cavity, and in addition the sheet is subjected to at least partial dragging within the mould without it being retained along the edge of said cavity, independently of the order in which the two aforesaid operations are carried out and independently of any partial overlapping of said operations.
