A device including a base body and a resin feed device to fill the base body with resin. The base body includes an area not to be filled by the resin and an opening at a level of an upper end, the area not to be filled being situated at the upper end of the base body and extending inside the base body. The resin feed device includes an injection column coinciding with the opening and extending inside the base body so that, during the filling, resin enters the interior of the base body via the injection column. The injection column extends more deeply inside the base body than the area to be filled, wherein when, during the filling, the resin reaches the injection column, air trapped in the base body is compressed, whereby the filling is stopped automatically, so that the area not to be filled is not filled. |
