い。Extruded products are generally formed by extruding asbestos cement or other materials kneaded in a pug mill through a die using a screw. By converting such a molded product into a die, it is possible to continuously and efficiently manufacture a product with a free cross-sectional shape. In other words, it is possible to easily manufacture not only blank parts and other products with various cross sections, but also products with a continuous pattern in one longitudinal direction. Further, by pressing a press roller against the uncured molded product immediately after extrusion, a shallow simple linear pattern intersecting the extrusion direction can be imparted. However, in this case, the complicated patterning requires strong pressing pressure, which causes deformation of the molded product, making it impossible to obtain a good product.

施に好適な装置の一例を第１図〜第３図に示す。In order to achieve the above-mentioned object, the present invention, when manufacturing an extrusion molded product using an extrusion molding machine, a roller having an uneven pattern on the cylindrical surface is rotatably attached to the upper surface of the die, and the roller is used during the extrusion process. The gist of this invention is a method for manufacturing a patterned extrusion molded product, which is characterized in that the uneven pattern of the cylindrical surface of the roller is transferred to the surface of the molded product by pressing the roller onto the surface of the product and rotating in synchronization with the extrusion speed of the molded product. It is something. An example of an apparatus suitable for carrying out the present invention is shown in FIGS. 1 to 3.

Patterned roll
has a complicated uneven pattern on its cylindrical surface. This roll 1 is supported by bearings fixed to both sides of the die 2, and is rotatably located at a position where its cylindrical surface abuts the upper surface of the molded product 4. The portion of the die 2 where the roll 1 is installed fully receives the lower and side surfaces of the molded product 4.

When the molded product 4 is extruded, the molded product 4 is extruded with an arbitrary cross-sectional shape by the die 2, and a roll l is placed on the top surface of the molded product 4 at a position where the bottom and side surfaces of the die 2 are still holding the uncured molded product 4. are in contact with each other, and the molded product 4 touches the bottom plate of the die 2 and the core 5.
The pattern on the circumferential surface of the roll 1 is transferred while the roll 1 is held in place. Therefore, no deformation occurs even in the uncured molded product 4. In this case, the pressing strength between the cylindrical surface of the roll and the surface of the molded product and the mutual positional relationship between them can be easily adjusted, and the forces are balanced between the die, roll, and molded product, so a separate pressing device is not required. etc. is not required.

The molded product 4 extruded in this manner is conveyed by a roller conveyor 6 like a normal extrusion molded product.
本発明により、押出成形品の形状を変形させたり、ベル
