How to improve the productivity of veneers

Improving the productivity of veneer is one of the crucial measures to rationally use wood resources and reduce product costs. Improve the quality of veneer cutting. Reduce the thickness deviation and reduce the difference between the actual thickness and the nominal thickness of the veneer. It is also a significant aspect of improving veneer productivity. Increasing the volume of the rotary-cut veneer and reducing the useless amount is another crucial aspect. Increasing the volume of the rotary-cut veneer and reducing the useless material can increase the yield of the veneer by the following aspects.

Re-peeling of the residue wood core

For wood with a large diameter, the wood can be cut to a smaller diameter with a spindle veneer peeler at first, and then rotary cut by spindle-less machine. The core diameter after the cutting of spindle-less lathe is about 30 mm. The remaining wood core can be re-peeled by the wood shaft rotary cutting machine produced by Shandong Changsheng.

Use of the veneer splicing machine

Some wood sections cannot directly reduce the diameter of the core due to defects such as heart rot and cracking, This part of the defect can be broken off to produce a veneer with a smaller format. Then splicing through a veneer stitching machine or an automatic splicing machine. This can also improve the use of wood very well.

Reasonable grading of boards

In the process of veneer production, the board rate can be improved by grading the quality of the veneer. The boards are divided into two categories by sensors before stacking. Class A will enter the stacker and prepare for the drying process. Class B broken veneers or narrow veneers will be disposed of separately, manually selected and then repaired and tailored.

Wet veneer edge banding

In particular, when the thin veneer is rotated, an adhesive tape is applied to both sides of the veneer to prevent the veneer from being torn in the subsequent processing, resulting in a loss. The veneers are placed in a roll for one hour and then dried so that the adhesive tape is tightly glued to the veneer.
