Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing decorative veneers that can efficiently produce a large number of decorative veneers having similar wood grain patterns.

Conventionally, the method of obtaining such a decorative veneer is as follows:
There are known methods of cutting wood frits cut from logs using a slicer or half-round rotary lace, but in both of these methods, decorative veneers are obtained by cutting the wood frits cut from logs intermittently. Therefore, the production efficiency is low, and it is difficult to obtain a large frit due to the depletion of high-quality large-diameter wood, so it is difficult to form a wide decorative veneer.

The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to continuously obtain wide decorative veneers with similar wood grain patterns using small-diameter wood by rotary lace with high productivity. The present invention provides a method for manufacturing a decorative veneer that enables the following.

The present invention will be described below with reference to the accompanying drawings.

First, a cut groove 2 is provided along the length of the log 1, facing toward the center and reaching the chuck.

The cut grooves 2 may be provided before the wood is boiled or steamed, or may be provided after the wood is boiled and steamed. especially,
When using hardwoods such as oak and birch as logs, end cracks often occur during boiling, so if you prepare the above-mentioned cut grooves 2 before boiling,
This is preferable because the internal stress generated by heating is relaxed and absorbed in the groove, thereby preventing the occurrence of end cracks.

Further, when a long log is cut into a predetermined size and used, if the cut grooves 2 are provided before cutting, problems such as cracking at the end of the log when cutting the log can be eliminated.

Furthermore, if the raw wood 1 has defects such as cracks from the beginning, if the cut grooves 2 are provided so as to include the defects, such defects can be removed with a decorative layer after cutting with the rotary race described later. You can eliminate the work of removing it from the board.

Next, the raw wood 1 provided with the cut grooves 2 is cut using a rotary race. In the drawing, 3 is a rotary lace knife, 4 is a push shear bar, and 5 is a chuck, which are the same as those used when stripping lauan veneer.

By stripping this rotary lace, log 1
The outer periphery of the veneer is cut into a decorative veneer 6 whose grain is divided by cut grooves 2.

The decorative veneer 6 thus obtained exhibits a wood grain pattern developed from the outer circumferential surface of the log 1, and the next decorative veneer 6' that is successively cut is also similar to the previously cut decorative veneer. It has an appearance very similar to the grain pattern of board 6.

As described above, the present invention is similar to the case where decorative veneers are obtained by a slicer etc. in that the wood grain patterns of decorative veneers obtained by continuous cutting are very similar to each other. For cutting, a wood fritsch is used,
Since only one side of the wood is cut, only a narrow decorative veneer can be obtained.However, according to the method of the present invention, the raw wood has cut grooves extending along the longitudinal direction toward the center and reaching the chuck part, and is then cut into a rotary lace. Since the method involves stripping the wood in its entirety, it is possible to obtain a wide decorative veneer even if the wood is small in diameter.Moreover, the cutting work is carried out continuously, resulting in high production efficiency, and the resulting decorative veneer is Unlike regular rotary veneer, the wood grain pattern is always cut at a fixed position, so the advantage is that the work of cutting into the specified wood grain pattern can be omitted, and the patterns of the decorative veneer can be easily aligned. It has the following.

In addition, if the above-mentioned cut grooves are provided before the wood is boiled and steamed, it is possible to prevent the occurrence of end cracks due to the boiling and steaming process. Providing cut grooves in the grooves has the advantage that removal work for defective parts can be omitted.
