S2：The bending wood chip of above-mentioned drying is put into liquid medicine and soaked, temperature control is at 25-28 DEG C, continuous dipping 8-
12h；
S3：Above-mentioned soaked bending wood chip is loaded into vacuum pressed tank, tank door is closed, vacuumizes, then add step
Liquid medicine in S2, boosting, pressurize, decompression, discharge opeing, rear vacuum, emptying, go out tank；
S4：By it is above-mentioned go out tank bending wood chip dried using steam, Steam pressure control is in 0.02-0.8Mpa, temperature
Degree control is dried to water content in 7-12% at 140-150 DEG C；
S5：The good bending wood chip of above-mentioned drying is opened into sawtooth at the both ends of length direction respectively, while in bending wood chip
Open the groove being engaged with sawtooth in right-angle folding crook；
S6：By it is above-mentioned hold sawtooth successfully and be superimposed with the bending wood chip of groove with adhesive to refer to be connected into refer to spreading bar, then use gluing
Agent, which refers to finger spreading bar superposition, is connected into finger-jointed plate.
Preferably, the liquid medicine in the step S2 is wood preservation liquid medicine, to prevent and treat timber mould and Stain fungi.
Preferably, dwell pressure is 1.0-1.4Mpa in the step S3, when a length of 30-45min.
Controlled as -0.98Mpa with rear vacuum pressure preferably, being vacuumized in the step S3.
Preferably, a length of 145-155h during steam drying in the step S4.
Preferably, the adhesive is the double environmentally friendly jigsaw special glues of combination of HT-988 types.
The present invention has the advantages that compared with prior art：
The double-deck superposition finger-jointed plate of the present invention is easy to finger and connect, and refers to the sheet material close and firm after connecing, in a longitudinal direction stress
Evenly, it is unlikely to deform.
