模様はその効果を強調するために模様の深さをなるべく
深く1例えば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, continuous grooves are added to the surface in the same direction as the extrusion direction, but to further improve the appearance, discontinuous uneven patterns (hereinafter referred to as embossed patterns) are used. 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.

ルを押出中の未硬化成形体に押圧して未硬化成形体と同
調回転させ、模様を未硬化成形体に転写する方法がある
が、その転写機構を模式図として断面を第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l(押出方

この変形はロールが更に回転して未硬化成形体を離脱し
た過程(B)においては更に拡大され、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, the uncured molded body 1 (the extrusion direction is shown by the arrow) obtained by extrusion molding the base material has a pattern transferred thereto by the pattern protrusion 3 of the roll 2 (the rotational direction is shown by the arrow) pressed thereon. However, the process in which the protrusion enters the uncured molded body (
In A), the X portion of the uncured molded body is scraped by the protrusion, which causes a bulge in the Y portion;
This deformation is further magnified in the process (B) when the roll rotates further and leaves the uncured molded body, and the outline of the transferred pattern becomes extremely unclear from 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2mm程度
の極く浅い模様しか付けられない欠点がある。For this reason, patterning using a roll has the disadvantage that only a very shallow pattern can be formed with a depth of about 2 mm at most.
