ABSTRACT:
A perforated drum coating machine which can readily be set up so as to be suitable for the coating of either tablets or the like, or spheroids. The machine contains at least one securing means which is attachable to the perforated drum, and at least one mesh member consisting of suitable mesh which is edged with thin springy material, and a strip of deformable rubber or plastics material which is positioned against the inward facing part of the edge of the perforated part of the drum at two or more arcuate portions thereof. The or each securing means is adapted to engage with and secure, on the inside of the drum, two mesh member edges. The total area of the mesh member(s) is essentially the same as the area of the perforated part of the drum. The deformable strips are positioned between at least two mesh member edges and the said arcuate portions of the perforated drum. The edges of the mesh member(s), which are adjacent the deformable strips which are themselves adjacent the said arcuate portions, are slightly over-long (i.e. in a circumferential sense), and they are sprung in an outward direction so as to be a tight fit against the deformable strips and, through said strips, against the arcuate edges of the perforated part of the drum.
