ABSTRACT:
An apparatus for enrobing medicine tablets in gelatin and employing a main linked track of die blocks with each block having a number of recesses formed in its top surface. A revolving co-operating die device in the form of another linked track or a cylindrical rotary die is adjacent to and in contact with the main linked track. This device also has a plurality of recesses, each of which is cooperable with a recess of similar size in the main link track to provide an enclosed cavity at at least one point along an upper path traversed by the main link track. This cavity is capable of holding one of the tablets. A first elastic gelatin strip is delivered to the main linked track and positioned for movement along its upper path. A vacuum system causes portions of the first gelatin strip to be pulled and stretched against walls of recesses in the die blocks to form tablet receiving depressions. A tablet dispenser drops tablets into these depressions. The tablets then move with the first gelatin strip to a region of contact between the main linked track and the die device. A second gelatin strip is delivered to the apparatus so that it is laid over the first gelatin strip when the two strips reach the region of contact. Portions of the second strip are stretched in the recesses of the die device in order to enrobe the tablets.
