Substrate-making apparatus comprises substrate-providing unit, cooler, skin layer-providing unit, rolling unit having textured roller for skin layer, and cutting unit in sequence

摘要

A substrate-making apparatus comprises a molten substrate-providing unit; a cooler provided next to the substrate-providing unit; a molten skin layer-providing unit; a rolling unit for rolling the molten skin layer and the cooled substrate material, wherein the rolling unit has at least two rollers and the roller, which rolls the skin layer, has a texture to form a predetermined surface profile on the skin layer; and a cutting unit next to the rolling unit. A substrate-making apparatus comprises a substrate-providing unit (10) providing a molten substrate material (22) with a predetermined width; a cooler (20) provided next to the substrate-providing unit to cool the substrate material; a skin layer-providing unit (24) to provide a molten skin layer (26) onto the substrate material; a rolling unit (30, 32) rolling the molten skin layer and the cooled substrate material, wherein the rolling unit has at least two rollers and the roller, which rolls the skin layer, has a texture to form a predetermined surface profile on the skin layer; and a cutting unit (36) next to the rolling unit to cut the substrate material and the skin layer to have substrates with the surface profile. An independent claim is also included for a method of making a substrate comprising providing a molten substrate material; molding the substrate material to have a predetermined width; cooling the substrate material; providing a molten skin layer on the substrate material; rolling the cooled substrate material and the molten skin layer to form a surface profile on the skin layer; and cutting the substrate material and the skin layer.
