Process for manufacturing signalling posts, preferably from rubber. If the posts are solid or hollow, this process is characterized in that the post is manufactured from a mould where vulcanization takes place by compression, transfer or injection. If the post has an inner core 2, the process is characterized in that, firstly, a treatment of the core 2 is carried out, and then a glue is applied to the core followed by drying, and then the inner core 2 is heated to an approximate vulcanization temperature which is a function of the material employed, and it is then introduced into a mould and into the latter are incorporated additives for conferring hardness and elasticity or mechanical strength and vulcanization takes place. Also included is a signalling post manufactured according to any one of the two processes mentioned, which is of the fixed, removable or relief type. <IMAGE>
