A method and a device for filling a coating material. According to the method, for the purpose of preventing a coating material bag from being burst or a paint from being shorted during painting even if the filling/pushing-out of the paint into the coating material bag is repeated, a residual coating material discharging step is performed before a coating material filling step. In the residual coating material discharging step, a hydraulic fluid is fed into a working fluid chamber (6) on the outside of the coating material bag (5) to squash the coating material bag (5) by its feed pressure so as to push out the remaining coating material until the coating material bag (5) is emptied . In the coating material filling step, when a tank (C) for filling the coating material having the coating material bag (5) is removed from a coater (T) and the coating material is filled in the coating material bag (5), a pre-set prescribed amount of coating material is fed into the coating material bag (5).

L~invention concerne un procédé et dispositif de chargement d~un matériau d~enduction. Selon le procédé, pour empêcher l~éclatement d~un sac de matériau d~enduction ou pour éviter la pénurie de peinture pendant l~opération de peinture même si l~on répète le chargement/l~éjection de la peinture dans le sac de matériau d~enduction, une phase de décharge de matériau d~enduction résiduel est réalisée avant une phase de chargement de matériau d~enduction. Dans la phase de décharge de matériau d~enduction résiduel, on injecte un fluide hydraulique dans une chambre de fluide de travail (6) à l~extérieur du sac de matériau d~enduction (5) pour écraser le sac de matériau d~enduction (5) par sa pression d~alimentation de façon à expulser le matériau d~enduction restant jusqu~à ce que le sac de matériau d~enduction (5) soit vide. Dans la phase de chargement de matériau d~enduction, lorsque l~on enlève un réservoir (C) de chargement du matériau d~enduction possédant le sac de matériau d~enduction (5) d~un système d~enduction (T) et lorsque l~on verse le matériau d~enduction dans le sac de matériau d~enduction (5), une quantité prescrite prédéterminée de matériau d~enduction est introduite dans le sac de matériau d~enduction (5).
