Process and moulding plate used thereby, for manufacturing a road marking device

摘要

Procedure for making a ground surface indicator material with raised studs consists of making holes at the required intervals through a flat panel, placing the panel with its upper surface down on a horizontal moulding plate with cavities corresponding to the position of the studs and pouring a self-hardening polymer resin material through the holes so that it fills the cavities. The procedure for making a ground surface indicator material with raised studs (3) consists of making holes (4) at the required intervals through a flat panel (1) designed to be fixed to the ground, placing the panel with its upper surface down on a horizontal moulding plate with cavities corresponding to the position of the studs and pouring a self-hardening polymer resin material through the holes so that it fills the cavities. The holes are smaller than the studs and generally lozenge-shaped, while the studs can be hemispherical, pyramidal, conical, truncated conical or cylindrical, and of a different colour to the panel. The underside of the panel is preferably covered with a protective film layer prior to installation.
