本発明は、水硬性物質を主原料とする押出成形
体の凹凸模様付け方法に関し、特に、長尺の成形
体に鮮明な深い模様付けを行い得る方法に関する
ものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for imparting an uneven pattern to an extrusion molded product whose main raw material is a hydraulic substance, and in particular, to a method for imparting a clear and deep pattern to a long molded product. It concerns how it can be done.

装材として広く用いられている。
The main raw material is a hydraulic substance such as cement, hydraulic plaster, or a mixture of calcareous raw material and silicic raw material, and if necessary, reinforcing fibers, lightweight materials, hardening accelerators, etc. are added to this mixed raw material. The extruded product obtained by kneading it into a base material, extruding the base material, and curing it in natural, steam or autoclave conditions is widely used as interior and exterior materials.

３mm、でき得れば５mm以上とすることが望まれて
いる。 In order to improve the appearance of extruded products, there are products that have continuous grooves on the surface in the same direction as the extrusion method, but to further improve the appearance, discontinuous uneven patterns (hereinafter referred to as embossed patterns) are added. In order to emphasize the effect of the embossed pattern, it is desired that the depth of the pattern be as deep as possible, for example, 3 mm, preferably 5 mm or more.

硬化成形体と同調回転させ、模様を未硬化成形体

として断面を第４図に示したように次の欠点があ
る。 One method of applying an embossed pattern is to press a roll engraved with the pattern onto the uncured molded product being extruded, rotate it in synchronization with the uncured molded product, and transfer the pattern to the uncured molded product, but the transfer mechanism is As shown in FIG. 4, which is a schematic cross-sectional view, it has the following drawbacks.
すなわち、素地を押出成形した未硬化成形体１

た過程(b)においてはさらに拡大され、転写された
模様は(c)にＺとして示した希望する模様とは輪郭
が極めて不鮮明となる。 That is, an uncured molded body 1 obtained by extrusion molding a base material.
(The extrusion direction is indicated by an arrow), the pattern is transferred by the protruding part 3 of the pattern of the roll 2 (the direction of rotation is indicated by the arrow) pressed against this, but the protruding part enters the uncured molded product. In the process (a), the portion X of the uncured molded body was scraped by the protrusion, which caused a bulge in the Y portion, and this deformation caused the roll to rotate further and separate from the uncured molded body. In step (b), the pattern is further enlarged, and the outline of the transferred pattern becomes extremely unclear compared to the desired pattern shown as Z in (c).
このためロールによる模様付けは深さが高々２

時に変形を生じ易く付けられた模様は更に不鮮明
になる。 For this reason, the depth of patterning with rolls is at most 2
It has the disadvantage that it can only create extremely shallow patterns of about mm size. Another method of applying an embossed pattern is to press a flexible sheet engraved with a pattern synchronously onto the uncured molded product being extruded to transfer the pattern, but this method also uses a roll as the pattern transfer mechanism. as well as having similar drawbacks to be similar to
Because the sheet is flexible, it tends to deform when pressed against an uncured molded body, making the pattern further unclear.
エンボス模様を付ける更に他の方法として模様
を彫刻した板体を押出中の未硬化成形体に押圧す
る方法がある。 Yet another method for applying an embossed pattern is to press a plate with an engraved pattern onto an uncured molded product during extrusion.

硬化後に研削等の加工を要していた。 This method includes, for example, a method of pressing a plate by moving it back and forth in synchronization with the advancing speed of the uncured compact being extruded, as disclosed in Japanese Patent Application Laid-open No. 60-253508. However, the previous pressed position and the next pressed position may be far apart, leaving a place with no pattern between them, or they may overlap, resulting in a disordered pattern, which is unsightly, especially for long molded objects.
After hardening, processing such as grinding was required.

In order to solve the above-mentioned problems, the present invention provides a method for patterning an extrusion-molded body using a hydraulic material as a main raw material, in which a plurality of plate bodies engraved with patterns are sequentially circulated, and the uncured plate bodies during extrusion are After constantly pressing two or more units in succession while synchronizing with the movement of the molded object,
This is a method for forming uneven patterns on an extrusion molded body, which is characterized by successively separating the plate and transferring the pattern engraved on the plate to the uncured molded body.

し、図示されない後続の板体も上記と同様に動作
する。 Next, the plate body 5b is connected to the plate body 5a, presses the uncured molded body 1 by the press 6b, and moves in the extrusion direction in synchronization with the uncured molded body 1 by the circulation device, and the plate body 5c is also connected to the plate body 5b, and the plate body 5d
is connected to the plate 5c and operates in the same manner as the plate 5b, and subsequent plates (not shown) also operate in the same manner as described above.
一方、板体５ａは未硬化成形体１と同調して移
動しつつ、プレス６ａによつて垂直に引上げられ
た後、循環装置によつて板体６ｄの位置に循環さ
れ押圧を繰返し、他の板体も同様である。 On the other hand, the plate 5a moves in synchronization with the uncured molded body 1 and is vertically pulled up by the press 6a, and then circulated to the position of the plate 6d by the circulation device and pressed repeatedly, and then The same applies to the plate.
本発明において各板体は、 未硬化成形体と同調して垂直に押圧する。 In the present invention, each plate is Press vertically in sync with the uncured molded body.
押圧中の板体は互いに連接している。 The plates being pressed are connected to each other.
未硬化成形体と同調して垂直に離脱する。 It separates vertically in sync with the uncured molded body.

する。 As a result, the pattern transferred by the plate does not have any patternless areas or overlapping patterns, and the pattern can be deep and clear. Moreover, the extrusion molding machine is continuous. Since the machine can be operated in a controlled manner, product quality is stabilized and productivity is improved.
なお、中子７は空孔８の無い押出製品を製造す
