The invention provides a continuous forming system for a laminated veneer lumber (LVL), which is a novel equipment invention in the field of wood processing in China, can replace similar imported equipment to improve the processing and utilizing efficiency and quality of fast-grow forest woods. The system comprises a belt conveyer, a mobile forming head and a forming belt conveyer, and is mainly used for continuous lengthening and forming of each veneer of the laminated veneer lumber. The continuous forming system has the advantages of realizing continuous lengthening and forming to the veneer, overcomes the defect that the traditional process requires manual forming, improves the processing efficiency of forming, and reduces the manual cost of forming; in the forming process, the veneer can be accurately positioned and lengthened, and the joint of each veneer is regularly separated, so as to ensure that higher quality and strength of the laminated veneer lumber after forming to accord with the requirement of international laminated veneer lumber quality standard; and continuously lengthening and forming avoids material waste caused by multiple times of trimming of the laminated veneer lumber to improve the material utilization of the veneer.
