  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings with respect to a method for manufacturing a flooring 8 which is one of the present examples. FIGS. 1 and 2 are plan views showing a standard size single plate sheet 3 and a large size single plate sheet 3 according to the present invention, respectively, and FIG. 3 shows an A of the large size single plate sheet 3 shown in FIG. It is sectional drawing in the -A line.

  In the drawings shown in FIGS. 1 to 3, reference numeral 1 denotes a decorative veneer, and reference numerals 2 and 2 </ b> A denote discarding plates arranged around the decorative veneer 1. Usually, the decorative veneer 1 boiles and softens a piece of wood having a beautiful surface called flitch, and cuts it with a slicer at a certain thickness. Thus, a plurality of decorative veneers 1 are obtained. However, this veneer 1 has a high water content when it is boiled, tends to be subject to fluctuations in the water content, warps, and easily deforms or cracks.

  In order to prevent this warp or the like, the obtained decorative veneer 1 is usually directly bonded to the flooring substrate 4 or, after being stored, moved and adhered to the flooring substrate 4 with a film or the like to prevent fluctuations in moisture content. Is done.

  In the present invention, a veneer sheet 3 as shown in FIGS. 1, 2 and 3, that is, a decorative veneer 1 and a discard veneer 2, 2 A, is manufactured as a single veneer sheet 3 in advance. The plate sheet 3 is adhered to the surface of the flooring substrate 4. The floor material substrate 4 to which the single-size sheet 3 having a standard size shown in FIG. 1 is attached is processed with a concave groove 5 on the surface of the discarded single plate 2A, and is colored or painted. Further, the real part 7 is processed on the side surface of the flooring substrate 4 to form a standard size flooring 8. Since the portion of the discarded single plate 2 is processed by the real part 7 and the portion of the discarded single plate 2A is processed by the groove 5, the width of the single plate 2 and 2A is different.

  In the present invention, a piece of wood 2 or 2A to be obtained is bonded and integrated around the flitch around which the decorative veneer 1 is obtained, and then cut with a slicer to make the decorative veneer 1 and the waste veneer 2 and 2A uniform. A single plate sheet 3 having a sufficient thickness is obtained. The size of the veneer sheet 3 is formed in accordance with the size of the floor material substrate 4. The thickness of the single sheet 3 is usually about 0.5 mm to 1.5 mm when a slicer is used.

Sheet 3 is obtained.

  As shown in FIG. 1, FIG. 2 and FIG. 3, the veneer sheet 3 comprises a veneer veneer 1, a veneer veneer 2, and a veneer veneer 2 A adopted as necessary. 3 is a standard size single plate sheet 3 for obtaining a floor material 8 subjected to surface grooving and actual processing, and the size of the standard size single plate sheet 3 is a standard used for one floor material. This corresponds to the size of the size flooring substrate 4. In order to cut a single large flooring substrate 4 to obtain a plurality of standard size flooring, the size of the large size single plate sheet 3 shown in FIG. The size of the single-size sheet 3 of the standard size is a multiple of the size. After the large size veneer sheet 3 is adhered to the large size floor material substrate 4, the large floor material substrate 4 is cut along the respective portions of the single plate 2 of the large size veneer sheet 3. Then, actual processing is performed on the side surfaces of the plurality of standard size floor material substrates 4 cut as necessary. The size and position of the decorative veneer 1 and the discarded veneers 2 and 2A are determined by the shape of the floor material 8 finally obtained for the veneer veneer 1 and the discarded veneers 2 and 2A.

  Since the single veneer 1 or 2A is positioned and fixed around the decorative veneer 1, even if the moisture content of the veneer 1 fluctuates, the veneer 1 is less likely to warp, deform or crack. Therefore, even when a certain amount of time is required until the single plate sheet 3 is bonded to the flooring substrate 4 after the single plate sheet 3 is formed, it can be easily stored or moved. Further, if a backing material (not shown) is arranged and integrated on the back surface of the single plate sheet 3, warpage and deformation of the single plate sheet 3 can be effectively prevented.

  When the veneer sheet 3 is bonded and integrated to the flooring substrate 4, the veneer sheet 3 is formed to have a uniform thickness without steps by the above manufacturing method. It can be carried out.

  In many cases, the floor material substrate 4 is a plate-like body made of a wood material such as plywood, PB, or MDF. After the veneer sheet 3 and the flooring substrate 4 are integrated, a concave groove 5 such as a V-shape or a U-shape is formed in the surface of the single-sheet sheet 3 which is the surface of the veneer 2A as necessary. The Since this ditch | groove 5 is formed using the discarding board 2A part of the veneer sheet 3, the decorative veneer 1 is not cut.

  FIG. 4 is a partially cut-away sectional view showing a standard size flooring 8, and cutting the side surface of the standard size flooring substrate 4 to which the standard size single plate sheet 3 is attached to cut the real part 7. The formed flooring 8 is shown in the figure. A recessed groove 5 is formed in the discarded single plate 2 </ b> A portion of the single plate 3. A chamfered portion 6 is formed in the concave groove 5 and the real portion 7.

  The standard size flooring 8 shown in FIG. 5 is obtained by sticking the single large veneer sheet 3 shown in FIG. 2 to one large flooring substrate 4 and then the large size veneer sheet 3. A standard-size flooring 8 obtained by cutting along a single-cut single plate 2 to produce a plurality of standard-size flooring substrates 4 and performing actual processing around the end surfaces of the standard-sized flooring substrates 4.
