    摘要: According to the improved process sheets of thermoplastic material are embossed especially on both faces by means of a pair of embossing rollers in such a manner that the embossing roller is maintained at a temperature within the plastic temperature range of the thermoplastic material, and the sheet forwarded to the roller has a temperature in the range of from the second order transition temperature of the thermoplastic material and a temperature superior to it by about up to 70.degree. C.; the sheet being forwarded at a speed of from 5 to 200 m/min and subjected to an embossing pressure of from 100 to 500 N/cm. This process prevents undesirable alteration of the pattern first embossed in the second embossing operation in the case of double-face embossment of the sheet. The embossed sheets may be applied for decoration purposes or the coating of furniture, as well as for writing.

    摘要: The process of the present invention is for the surface treatment on both sides of a substrate by means of electric corona discharge, while simultaneously treating both surfaces of the substrate with a carrier gas/aerosol mixture introduced into the corona discharge zone. The arrangement for carrying out this process comprises a corona discharge device, consisting of a generator, high voltage electrodes, to which alternating current is applied by the generator, as well as grounded counter electrodes, a device for the atomization of liquid into a suspendable aerosol, which is connected via a transport line for the aerosol to the corona discharge device, and a blower, which is connected to the atomizer device and conveys the carrier gas/aerosol mixture to the corona discharge device. The electrodes and counter electrodes together form a gap for the substrate to be treated.
