ABSTRACT:
Method and apparatus for sealing gelatin capsules having cylindrical cap and body portions arranged in telescoping relationship to contain a medicament therein comprising a capsule-sealing machine for continuously conveying capsules from a supply hopper to a capsule-rectification station wherein the capsules are reoriented and delivered in endwise, cap-down abutment to capsule-wetting stations where a suitable sealing liquid is applied to the capsules at the seams of their cap and body portions to be located between the overlapping side walls of the cap and body portions of the capsules, and wherein the capsules are conveyed from their wetting stations in peripheral pockets of a rotating drum dryer to a capsule heating and sealing section where the capsules are heated by convection and conduction to seal the cap and body portions.
