Abstract
An apparatus for making substrates is consisted of a substrate providing unit, a cooler, a skin layer, a rolling unit and a cutting unit in sequence. The substrate providing unit provides a molten substrate material with a predetermined width. The cooler, which is a conveying unit, solidifies the substrate material and conveys it to the rolling unit. The skin layer providing unit provides a molten skin layer onto the substrate material. The rolling unit rolls the molten skin layer and the solidified substrate material and forms a predetermined surface profile on the skin layer at the same time. The cutting unit cuts the substrate material and the skin layer to have a plurality of the substrates.
