An apparatus for enrobing tablets in a gelatin layer includes a pair of die assemblies with each assembly including a rotatable, cylindrical die support and a series of die blocks mounted on this support for movement along a circular path. Each block has recesses formed in a top surface thereof and each recess of one assembly cooperates with a similar recess in the other assembly to form a cavity at a nip formed by the two assemblies. Each cavity is dimensioned to receive loosely therein one of the tablets. Two casting drums deliver gelatin strips to the die assemblies and each strip is pulled by one assembly into the nip. A time tablet dispensing mechanism is used to dispense tablets onto one of the strips at a feeding location. The preferred die blocks are made of hard plastics material. The tablet dispensing mechanism employs vacuum applying members operatively connected to a vacuum source and air cylinder transfer mechanisms for moving these members from a tablet pick-up position to the feeding location.
