In 1812, French Machinist obtained the first patent for veneer sawing machine. By 1825, this veneer sawing machine could not be used in industrial production. After that, it was improved and manufactured in Hamburg, Germany. The first veneer slicer was developed by the Frenchman Charles Picot and was patented in 1834. It took nearly 30 years before it was used in industrial production. The development of the plywood industry benefited from the invention and application of the veneer peeling machine. There are several theories about the invention of the first peeling machine. The first peeling machine was invented in 1818; in 1819, the Russian Professor Feissel invented In 1840, John Dresser obtained the U.S. patent No. 1758 for the rotary cutter, and Carand was in France in 1844. Some people think that the rotary cutter was invented by the British engineer Fevilear. Obtained another patent for rotary cutting machine. In the middle of the 19th century, Germany established its first veneer manufacturing plant. Most of the rotary cutting machines were French, and Germany also imported American-made rotary cutting machines. After 1870, the A.Roller company in Berlin, Germany, produced a relatively simple peeling machine. Before the First World War, due to the continuous advancement of lathe technology, the plywood industry developed rapidly. In the 1890s, the quality of plywood has been greatly improved, and the market has gradually opened up since then, 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
