Method and apparatus for encapsulating small articles such as medicines in caplet or cylindrical form are disclosed. Gelatin half capsules are formed on the pins (11) of pin blacks. ( 10) and are delivered to a station at which they are trimmed and fitted over the opposite ends of the product to be encapsulated. The capsule halves are first dried to a condition in which they have about 20 wt. % moisture and are thereafter press fitted over the ends of the caplets and allowed to dry to shrink fit tightly onto the caplets' making it virtually impossible to remove them from their gelatin coverings without leaving visible evidence of tampering. The finished product has a smoother outer surface which lends itself to overprinting.

Procédé et appareil d'encapsulation de petits articles tels que des médicaments de forme cylindrique ou des pastilles. Des demi-capsules de gélatine sont formées sur les pointes (11) de blocs (10) et sont renvoyées vers un poste où elles sont taillées à mesure et adaptées sur les extrémités opposées du produit à encapsuler. Les moitiés de capsules sont d'abord séchées jusqu'à avoir une humidité d'environ 20 % en poids puis elles sont adaptées par pression sur les extrémités des pastilles et on les laisse sécher afin d'obtenir un assemblage serré par rétrécissement qui rend pratiquement impossible l'enlèvement des couvertures de gélatine sans laisser de traces visibles de spoliation. Le produit fini présente une surface externe plus lisse qui se prête à l'impression.
