Abstract

PURPOSE:To work an excellent rugged pattern on a shape at low cost by rotating and compressing a shape having plural rows of small projections on the surface in longitudinal direction by rolls provided with irregular and discontinuous rugged pattern on peripheral surface. CONSTITUTION:Plural rows 2 of small projections extending continuously in longitudinal direction on the surface 2 of a shape 1 for architecture are formed by an extruding machine. The shape 1 is fed in feeding direction A at specified speed and inserted between two rolls 4. Rolls 4 are rotated in the direction B corresponding to the feeding direction A and compress the shape 1. A rugged pattern 7 is formed on peripheral faces 6 of the rolls 4 irregularly and discontinuously. Rows 3 of small projections on the shape 1 are squashed corresponding to the rugged pattern 7, and a rugged pattern excellent in design is formed on the surface 2 of the shape 1.

Description

[Detailed description of the invention] The present invention relates to a method for secondary processing of lumber.

Conventional molded materials, such as molded materials for buildings, are used without any pattern on their surfaces; however, molded materials that expose their appearance both indoors and outdoors give the viewer a strong metallic impression. Therefore, its use in places where metallic appearance is disliked spoils the aesthetics and poses problems in terms of design.

2. The present invention solves these conventional problems and provides a secondary processing method for sawn lumber that can process and form a concave-convex pattern that is excellent in design, has a simple forming process 1, and has a low manufacturing cost. With the goal. Therefore, one feature of the present invention is that a plurality of rows of small protrusions extending continuously in the longitudinal direction of the surface are formed to form the lumber, and the above-mentioned table 1 of the t*gau shaped material is formed.
ili is rotated and compressed by a processing roller means having an irregular and discontinuous uneven pattern on the circumferential surface, thereby crushing the continuous row of small protrusions irregularly and discontinuously, thereby creating arbitrary unevenness on the surface of the sawn lumber. The point is that the pattern is processed and formed.

The present invention will be explained in detail below based on the embodiment shown in Figure 1 #i.

In Figures 1 to 4, (1) is extruded by an extruder, and the axillary wrinkle material (1) is extruded using an extruder.
On the surface (2) of the mold material (1), there are a plurality of small central rows ■1 (31...) extending continuously in the longitudinal direction. ).The small protrusion row +31 (31... is formed at the same time when the mold material (1) is wrinkled.The small protrusion row f31 (the cross-sectional shape of 31 is l
It may have any shape as shown in Figures (1) to (Φ).

8 It is also preferable that the cross-sectional shapes of the adjacent small protrusion rows (31 (31...) are different from each other. Distance CI between the adjacent small protrusions +31 +31... ) may also be optional.

An irregular and discontinuous uneven pattern (7) is provided, and the height dimension of the uneven pattern (7) is also arbitrary. Roller means (4

Then, the upper and lower roller means (4) (4), which are rotationally driven in the feeding direction (rotation direction @corresponding to ARK) of the lid material (1) to be processed, work together with the feeding means to move the workpiece between them.

Note that the present invention is of course not limited to the above-mentioned embodiment 1PIIK, and is free to make various design changes. For example, in the above embodiment, the roller means (4) (4) are arranged in parallel in the vertical and vertical directions, but they are also arranged in parallel in the horizontal and horizontal directions. ) may be in the vertical direction.Furthermore, the roller means (4) (4)- may be supported by the rotary shaft (5) so as to simply rotate freely without being rotationally driven by the drive means, and the lid material (1) to be processed may be ) may be configured to pass through the roller means (4) (4) threshold only by means of the feeding means (4), or conversely, the feeding means (4) may be configured to pass through the threshold (4) without using the feeding means (9) and one of (4) (4) or may be constructed so that both rotary drives pass through F.

Furthermore, the number of the upper roller means (4) and/or the lower roller means (4) may be increased to make it more than one, or the surface of the profile (1) [+ (protruding from 21 (2)) The row of small protrusions to be formed 3) 6 (3)... and the roller means (41 (4) By deforming both shapes and changing the relative relationship between the two, it is possible to process and form a wide variety of uneven horizontal patterns without being limited to the patterns shown in the above embodiments. .Furthermore, the pattern material (1) is structured so that the uneven pattern (7) is formed only on one side (2), or in the case of a prismatic m material with a rectangular cross section, the uneven pattern is formed on all four surfaces. Do it.

The present invention has the configuration as described in detail above, and has effectively achieved the intended purpose. In particular, a processing roller means having an irregular and discontinuous uneven pattern on one surface of the lid material O having a plurality of small protrusion rows extending continuously in the longitudinal direction of the surface of the extruder is formed. Rotate and squeeze the
From this K, since an arbitrary uneven pattern is formed on the surface of the noodle material, the uneven pattern can be processed and formed continuously and easily, and the forming process is simple and the manufacturing cost is low. Moreover, it is possible to provide sawn lumber with an excellent design that does not have a metallic appearance even though it is made of metal.
