Abstract
Device for filling multiple blind holes. The invention involves a device that permits the filling of blind holes in an effective and controlled manner. It is composed of a mobile body (1) in airtight contact with the surface (10) containing the hole openings. The body (1) contains two slots, the first (2) of which is kept airtight from the exterior of the device and from the second slot (5), is separate and parallel to the direction of travel of the device, and is larger than the largest opening. The first slot exposed to the openings while moving is connected to a vacuum chamber (3), while the second slot exposed to the openings is connected to a reservoir (6) containing the product (7) to be transferred.

Device for filling multiple blind holes opening onto a surface, with a viscous product (7), the device comprising a translatory mobile body (1) the surface containing the openings, said body containing at least two slots, the first slot exposed to the openings while moving is connected to a vacuum chamber (3), while the second slot exposed to the openings is connected to a reservoir (6) containing the product (7) to be transferred, characterized by the fact that said body (1) is in airtight contact with the surface containing the openings of said blind holes and that the first slot (2) is kept airtight by a sealing spacing from the exterior of the device and from the second slot (5) by a distance, measured parallel to the direction of travel of the device, that is larger than the largest opening.
Method for filling multiple blind holes (11) with a viscous product (7), by implementing a body (1) having at least two slots and moved on the surface containing the openings, the first slot is connected to a vacuum chamber, while the second is connected to a reservoir (6) containing the product to be transferred, characterized in that the body (1) is in airtight contact with the surface (10) containing the openings of said blind holes and that the first slot (2) is kept airtight by a sealing spacing from the exterior of the device and from the second slot (5) by a distance, measured parallel to the direction of travel of the device, that is larger than the largest opening to be filled, and when the body (1) moves relative to the holes, the slot connected to the vacuum is the first to come into contact with the hole openings, followed by the second slot, so that the vacuum generated first in the holes draws in the product when it is exposed to the distribution slot (5), until the pressure within the hole is equal to that in the reservoir.
