The invention belongs to the field of manufacturing of recombined decoration veneers and particularly relates to a manufacturing method of a rectangular color-stripe pattern recombined decoration veneer. By adopting an assembly formed by combining same-color and multi-color assemblies, rotary assemblies and double veneer assemblies, the whole processing and manufacturing method is formed accordingto multiple rounds of arrangement and combination of multiple special processes such as angler sawing, angler slicing and special-shaped gluing. According to the trend and demands of the decoration market, different colors of rectangular color-stripe geometric-shaped patterns alternatively arranged in the length and width directions are made by adjusting the technical parameters such as assemblythickness, assembly mode, sawing angles and sawing thickness and are different from natural texture patterns such as imitated wood grains. The made rectangular color-stripe patterns are complicated and varied in color and make modern fashion and man-made design prominent. The manufacturing process is simple, operation is easy, veneer bonding is firm, the rate of finished products is high, and bending, deformation, air shrinkage or sun cracking of the obtained finished product decoration veneer is not likely.
