Abstract
The invention relates to a supply apparatus (100) for supplying at least one molding device (500) with a polymerizable mixture, comprising: a tank (110) where is stored the polymerizable mixture, a line (120) for supplying the at least one molding device with said polymerizable mixture, the line being connected to an outlet of the tank for receiving the polymerizable mixture and to an inlet of said at least one molding device, and means for making the polymerizable mixture circulate in said line. According to the invention, the line includes remove means (190) for removing the gas from said polymerizable mixture and for evacuating said gas out of said supply apparatus.
Claims15
A supply apparatus for supplying at least one molding device with a polymerizable mixture, comprising:
- a tank where is stored the polymerizable mixture;
- a line for supplying the at least one molding device with said polymerizable mixture, the line being connected to an outlet of the tank for receiving the polymerizable mixture and to an inlet of said at least one molding device, said line including remove means for removing gas from said polymerizable mixture and for evacuating said gas out of said supply apparatus;
- and
- means for making the polymerizable mixture circulate in said line;
- wherein said supply apparatus comprises an inert gas supplier connected to the tank so as to be able to add inert gas inside the tank, and
- wherein the means for making the polymerizable mixture circulate in said line comprises a pump located in said line for supplying the inlet of said at least one molding device with the polymerizable mixture.
A method for supplying a polymerizable mixture to at least one molding device, said method comprising the following steps:
- a) providing a tank containing the polymerizable mixture;
- b) providing a line for supplying said at least one molding device with the polymerizable mixture stored in said tank;
- and
- c) making the polymerizable mixture circulate in said line;
- wherein, during step c), the gas contained in the polymerizable mixture circulating in said line is removed and evacuated out of said line.
