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.

Abstract: The invention relates to 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 (box E1), b) reaching a set value of pressure (Ps) in the tank, smaller than the ambient pressure (box E2), c) continuously maintaining the pressure (P) in the tank at the set value of pressure while supplying the polymerizable mixture to the molding device (boxes E3, E4, E41, E42, E5, E51). The invention also relates to a supply device for supplying the molding device with polymerizable mixture.

Abstract: The invention relates to a device (1) for supplying at least one molding device (2) with a polymerizable mixture of at least two reactants. According to the invention, said supply device comprises: a buffer tank (10) suitable for receiving said polymerizable mixture via an inlet (101) of said buffer tank, a supply circuit (11), looped with said buffer tank, to convey the polymerizable mixture to an inlet (110) of said at least one molding device and including, beyond said inlet of the molding device, a return pipe (115) connected to the inlet of the buffer tank for sending a portion of the polymerizable mixture from said return pipe, and a filling pipe (42) of said buffer tank, connected to said inlet of said buffer tank, separate from the return pipe, wherein said buffer tank is also suitable for receiving said polymerizable mixture or at least one of said reactants from said filling pipe.
