Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the provision of a cutting blade on the side edge of a rotary cutter for forming V-grooves. The present invention relates to a method for processing a decorative architectural frame material, which improves processing accuracy and enables correct bending by making it possible to perform V-groove processing on the back surface of the decorative frame material.

In buildings, on the inner peripheral surface of openings such as doors or on discontinuities in walls such as the vertical edges of partition walls, architectural decorative frame materials with a cross finish or the like applied on one side, as shown in Figure 4, are used, for example. 3
A decorative frame 1 is attached and decorated by wrapping a backing material 5 around the backing material 5 and folding the decorative architectural frame material 3 into a U-shaped cross section. V groove and backing material 5
It is difficult to match the end faces with the decorative frame 1, and as a result, the decorative frame 1 is often distorted. The purpose of the present invention is to provide a method for processing decorative frame materials for buildings that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

The method of the present invention is a decorative frame material (hereinafter referred to as a frame material) for construction in the form of a long flat plate that has been subjected to a surface finish such as cross-covering and has been cut to the correct width dimension as shown in FIGS. 1 and 2. At the same time, the backing material 5 is attached to the back surface 4 of the frame material 3, and at the same time the side surface 7 of the backing material 5 is dimensioned using a rotary cutter 6 illustrated in FIG. 8 and 9 are recessed, both the frame material 3 and the backing material 5 are made of wood, and the backing material 5 is set to be slightly wider than the width of the final finish. In the example, the thickness is also formed thick in advance.

In addition, when pasting the backing material 5, it is aligned and pasted as accurately as possible using various automatic pasting devices. Rotary cutter 6
A rotary blade 10 having a convex center and a concave V-groove at the center having a groove angle of 900 on the outside thereof, and a rotary blade 11 having a concave V-groove at the center of 900 mm are arranged in a cylindrical shape having a length corresponding to a predetermined width dimension of the backing material 5. rotating blade 1
The rotary blades 10 and 11 are integrally fixed via the rotary blades 10 and 11.
A cutting edge 13 is also formed on the side edge of the rotating shaft 1.
4, the rotary blades 10, 11, 12 are symmetrically aligned with the rotary shaft 1 so that the left and right backing materials 5, 5 can be processed simultaneously.
It is fixed at 4. Note that the width dimension of the frame material 3 is properly cut in advance to a predetermined dimension using a running saw as described above. Therefore, one side edge 15 of the frame member 3 is guided by a guide piece (not shown), and the distance (0) between the outer edge 16 of the rotary blade 10 and the side edge 15 is set to 0.
2 and the back surface 4 of the frame material 3 by processing with the rotary cutter 6 while matching the gap size (
The side surface 7 is the cutting edge 13, 1 of the side edge of the rotary blade 10, 11.
3, V-grooves 8 and 9 for bending are simultaneously formed on the back surface 4 of the decorative frame material 3, and therefore the side surface 7 of the backing material 5 and the V-grooves 8 and 9 are formed at the same time. Aligned with the edges,
Furthermore, in this embodiment, the backing material 5 is
The back side of the frame is also finished at the same time, making it possible to accurately match the dimensions (t1) and (T2).As a result, by bending at each V-groove 8 and 9, a decorative frame with the correct dimensions and no distortion can be created. 1 can be formed. In summary, the method of the present invention can form a V-groove on the back side of a frame material at the same time as the side surface of a backing material, and can easily and efficiently form a V-groove that can be accurately bent. It can be suitably employed as a processing method.

[Brief explanation of the drawing]

Figures 1 to 3 each show an embodiment of the present invention, with Figure 1 being a sectional view showing the decorative frame material, Figure 2 being a sectional view showing the process of attaching the backing material, and Figure 3 being the rotating FIG. 4 is a sectional view illustrating a cutter, and FIG. 4 is a perspective view illustrating a decorative frame.

Claims (1)

[Claims] 1. The backing material is continuously attached to the back side of the decorative frame material, and a rotary cutter for forming a V-groove, which also has a cutting edge on the side edge, is used to measure the side surface of the backing material and simultaneously fold it onto the back side of the decorative frame material. A method for processing a decorative frame material for construction, which is characterized by providing a recessed V-groove for bending.
