Abstract
The invention relates to a device for depositing a surface coating on cores. The inventive device comprises a rotationally mounted drum for accommodating the cores, at least one spraying nozzle for depositing the surface material on the cores, a heating device for the inner space of the drum, an inlet and an outlet, and carriers which are provided for the cores and which are arranged inside said drum. The invention provides that the drum is designed as a longish cylinder and that second carriers are provided for the cores (11, 12). The second carriers transport the cores opposite the first carriers and are arranged such that they can be radially displaced in relation to the first carriers. The invention also provides that the drum is held in the device so that it can be quickly removed.
Claims5
An apparatus for applying a surface coating to cores comprising:
- a rotatably mounted drum for accepting the cores;
- at least one spray nozzle for deposit of the surface material onto the core;
- a heating device for the inside space of the drum;
- an inlet and an outlet opening;
- and
- at least one first and at least one second carrier arranged in the drum,
- wherein said drum is an oblong cylinder, wherein said at least one second carrier transports the cores in a direction opposed to the direction of said at least one first carrier, and wherein said at least one second carrier is radially offset, and further toward the interior of the drum relative to said at least one first carrier, and wherein the drum is journaled in the apparatus in a quickly removable fashion.
