In a method and a device for continuously manufacturing films, webs, and sheets
of plastics capable of forming optical images a melted plastic mass, pre-shaped
as a sheet, is guided into a roller gap of a calender, the roller gap formed between
a shaping engraving cylinder roller and a smoothing strip surrounding partially
the shaping engraving cylinder roller. The shaping engraving surface of the cylinder
roller is heated to melting temperature in the roller gap, wherein the melted plastic
mass is applied directly onto the shaping engraving surface of the heated cylinder
roller. A profiling is provided by cooling the melted plastic mass in the roller
gap by heat removal on a side facing the shaping engraving surface.
