In 1812, a French mechanic patented the first veneer saw, which by 1825 was not yet available for industrial production, and has since been improved and manufactured in Hamburg, Germany. The first veneer planer was developed by the Frenchman Charles Picot and patented in 1834, and it took nearly 30 years for it to be used in industrial production. The development of the plywood industry benefited from the invention and application of the veneer rotary cutting machine, there are several theories about the invention of the first rotary cutting machine, the first rotary cutting machine was invented in 1818, in 1819 the Russian Professor Phycel invented the rotary cutting machine, which was called thin wood planer at that time, and some people believe that the rotary cutting machine was invented by the British engineer Fevilear, and in 1840, John Dresser obtained a patent for a rotary cutting machine in the United States No. 1758, and in 1844 Carand obtained another patent for a rotary cutting machine in France. In the middle of the 19th century, Germany established its first veneer manufacturing plant, and most of the rotary cutting machines were French, and Germany also imported American-made rotary cutting machines. After 1870, the company A.Roller in Berlin, Germany, produced relatively simple rotary cutting machines. Before the First World War, the plywood industry developed rapidly due to the continuous advancement of rotary cutting machine technology. In the 90s of the 19th century, the quality of plywood has been greatly improved, and since then the market has gradually opened, and the production of plywood has developed rapidly, and many plywood factories have been established. In the United States, plywood did not become an official trade name until World War I.
