Application device and method to clean grinding surfaces in a machine for grinding ophthalmic lenses

An application device (10) configured to clean a grinding surface (113) of a grinding wheel (112) when said grinding wheel is mounted in a machine (100) for grinding ophthalmic lenses and when the machine comprises at least:

• the grinding wheel having the grinding surface (113) and being rotatably mounted in the machine around a first axis (118);
• and
• gripping members (104, 106) configured to receive an ophthalmic lens;
• and
• the application device comprising:
• a central portion (12) having coupling means (14) shaped so as to cooperate with the gripping members so as to mount the application device in the grinding machine;
• and
• a peripheral edge (16) and a disk made of felt, wherein the disk comprises an inside face configured to cooperate with the peripheral edge of the application device, so as to mount the disk on the central portion, and
• an external face forming an application surface, so as to directly cooperate with the grinding surface of the grinding wheel so as to clean the grinding surface,
• wherein the application device further comprises:
• a tank (22) that comprises a peripheral border and is configured to contain a cleaning solution;
• and
• delivering channels (30) that are arranged in the peripheral border of the tank and configured to guide the cleaning solution to the external face of the disk when a pressure is applied to the tank so as to squeeze the tank.
