Abstract

Sheet forming apparatus for use in cold forming plastics material includes a male forming member 12, the forward end 12a of which is roughened by e.g. abrading. The roughening obviates slippage of the sheet over the end of the member and thus prevents excessive thinning and perhaps breakage, of the sheet. The surface of the member is characterized by randomly scored discontinuities exceeding 25 microinches (RMS.).
