Abstract
A device for applying exactly dosed quantities of a viscous medium on support surfaces including a backing plate with an upper side and a lower side and at least one through hole, a dosing plate having at least one through hole and an upper side and a lower side which rests on the upper side of the backing plate, while it is possible to change the positions of the backing plate and the dosing plate relative to one another through shifting of the dosing plate or backing plate, an internally hollow tube whose outer wall is connected with exact fit to the whole wall of the hole of the backing plate at one end of the tube for each through hole of the backing plate, a die which can be passed through the through holes of the dosing plate and of the backing plate and through the internally hollow tube, for each through hole of the backing plate, and a wiper device operating parallel to the upper side of the dosing plate, by means of which a viscous medium can be introduced into the through hole of the dosing plate.
