Method for continuous embossing the surface of a cold prefabricated thermoplastic sheet by heat and pressure using an embossing roller

摘要

the invention relates to a process for continuous embossing the surface of a prefabricated, cold bulk thermoplastic plastic material under heat and pressure mitteils a stamping roller, the surface of a negative mould of formative narbung and which, at least in the area of their r umu00adfangsflu00e4che from silicongummi exists.this method is characterized by that the stamping roller unbeheizt and that the warming of the thermoplastic plastic material only in the area of its surface to a temperature of at least 150 c, preferably 180 250u00b0c, is carried out.temperature of the as level lead to such a softening to a liquefaction of industrial surface of bulk thermoplastic plastic that the thermoplastic plastics, even in the recesses of the pru00e4geoberflu00e4che the stamping roller from silicongu mmi penetrates and, therefore, the pru00e4geu00adstruktur exactly is transmitted.
