Abstract
Abstract A layered material for linings or coatings is made of a paste consisting principally of wood powder having a fineness similar to flour and vinylic glue, said paste being convertible into a foil by rolling cylinders, a press or other means. The layered material may be engraved, printed, painted or may withstand any finishing work as wood. To engrave or emboss the layered material an embossing belt or an embossing cylinder can be employed. To manufacture the embossing cylinder a method is disclosed in which even the model itself which has to be imitated can be used as matrix for the cylinder.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
114 words
A method for producing a dried, layered material for a lining or coating comprising forming a paste mixture consisting essentially of from between about 20% to 30%, by weight, acetone; from between about 10% to 15% by weight, toluene, from between about 3% to 5% by weight, lubricating oil; from between about 10% to 15% by weight, vinyl glue; from between about 25% to 30% by weight, powder wood; and from between about 10% to 20%, by weight of an inert filler; converting said mixture to a layer having a thickness of from between about 2/10 of a millimeter to a few millimeters; and drying the said layer by evaporating said acetone and toluene.
Claim 2
Independent Claim
114 words
A method for producing a dried, layered material for a lining or coating comprising forming a paste mixture consisting essentially of from between about 20% to 30%, by weight, acetone; from between about 10% to 15% by weight, toluene, from between about 3% to 5% by weight, lubricating oil; from between about 10% to 15% by weight, vinyl glue; from between about 25% to 30% by weight, powder wood; and from between about 10% to 20%, by weight of an inert filler; converting said mixture to a layer having a thickness of from between about 2/10 of a millimeter to a few millimeters; and drying the said layer by evaporating said acetone and toluene.
Claim 3
Dependent Claim
16 words
The method of claim 1 wherein said paste mixture is converted to said layer by pressing.
Claim 4
Dependent Claim
19 words
The method of claim 1 wherein said paste mixture is converted to said layer by means of rolling cylinders.
Claim 5
Dependent Claim
18 words
