Abstract
Abstract An apparatus for the application of a controlled quantity of finely divided particulate material on a tacky surface, without imparting any shearing force, having a porous, rotating, laterally movable, cylindrical cartridge for storing and dispensing said particulate material which performs a sieving operation to break up particle aggregates prior to dispensing said particulate material, a roller for transferring said particulate material from the dispensing cartridge to the tacky surface as the roller moves over said surface and, a housing for said elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
An apparatus for applying particulate material to a tacky surface comprising, within a housing: 1. a cylindrical sieve for breaking up agglomerates in the particulate material to form smaller particles of controlled size and for dispensing the particles to a depositing means; and 2. depositing means comprising at least one roller for applying the particles to a tacky surface without applying shear force, wherein said cylindrical sieve is driven by said roller and is free to move laterally within said housing.
Claim 2
Independent Claim
81 words
An apparatus for applying particulate material to a tacky surface comprising, within a housing: 1. a cylindrical sieve for breaking up agglomerates in the particulate material to form smaller particles of controlled size and for dispensing the particles to a depositing means; and 2. depositing means comprising at least one roller for applying the particles to a tacky surface without applying shear force, wherein said cylindrical sieve is driven by said roller and is free to move laterally within said housing.
Claim 3
Dependent Claim
15 words
An apparatus according to claim 1 wherein said cylindrical sieve has a non-circular cross section.
Claim 4
Dependent Claim
25 words
An apparatus according to claim 1 wherein the freedom of movement of said cylindrical sieve is governed by an adjustably positionable member in said housing.
Claim 5
Dependent Claim
15 words
An apparatus according to claim 1 having means for embedding particles into a tacky surface.
Claim 6
Dependent Claim
17 words
An apparatus according to claim 4 wherein said means for embedding comprises one or more retractable pads.
