Title:
METHOD FOR FORMING RECESSED AND PROJECTED PATTERN ON EXTRUDED CEMENT PRODUCT
Document Type and Number:
Japanese Patent JPH07171815
Kind Code:
A
Abstract:
PURPOSE: To easily form a deeply recessed and projected pattern on a surface of an extruded cement product by pressing.
CONSTITUTION: When a recessed and projected pattern is to be formed on a surface of a cement molded piece just after extrusion by pressing, a recessed and projected pattern is formed by pressing the surface of the cement molded piece by an upper press mold 1, that has deaerating vents 2 on the bottom of recessed faces 1A of the upper mold 1 forming the projected pattern or the product and peripherally has a frame for restricting the profile of the product. An air pressure is released through the deaerating vents 2. Flow of the cement is prevented by the peripheral frame.
