Abstract
A metering device is disclosed for regulating the depth of flowable product coating a surface movable relative to the metering device by directing an air curtain towards the surface. The metering device comprises a body (10) having an interior chamber (12), an inlet for connecting the chamber to a source of gas under super-ambient pressure; and an opening (16) communicating with the chamber and having a mouth through which gas is discharged from the chamber towards the surface to form the air curtain. A porous or reticulated membrane (18) is secured to, or formed integrally with, the body of the device to lie in the path of the gas discharged through the mouth of the opening.

A product metering device for regulating the depth, or leveling, of a flowable product coating a surface that is movable relative to the metering device by directing an air curtain towards the surface, the metering device comprising a body having an interior chamber, an inlet for connecting the chamber to a source of gas under super-ambient pressure;
- and an opening communicating with the chamber and having a mouth through which gas is discharged from the chamber towards the surface to form the air curtain;
- wherein a porous or reticulated flow regulating membrane is secured to, or formed integrally with, the body of the device to lie in the path of the gas discharged through the mouth of the opening.
A system for applying to a surface an even coating of a flowable product, in which system an excess of the product is placed on the surface and the surface is moved beneath a metering device that directs an air curtain towards the surface in order to spread the product evenly over the surface in order to achieve a desired coating depth, wherein the metering device comprises a body having an interior chamber, an inlet connecting the chamber to a source of gas under super-ambient pressure;
- and an opening communicating with the chamber and having a mouth through which gas is discharged from the chamber towards the surface to form the air curtain, and wherein a porous or reticulated flow regulating membrane is secured to, or formed integrally with, the body of the device to lie in the path of the gas discharged through the mouth of the opening.
