Claims9
A process for the production of divisible tablets by molding a melt containing an active ingredient in a calender with two counter-rotating molding rolls which are in contact along a surface line, at least one of the molding rolls having depressions for receiving and molding the melt to tablets, wherein a first molding roll of the two molding rolls is used in which the depressions are divided by n bars, where n.gtoreq.1, which bars extend essentially as far as the surface line, and form a score, and as a second molding roll of the two molding rolls there is used either
- (i) a molding roll with corresponding depressions which are divided by n' bars which bars extend essentially as far as the surface line of the molding roll and form a score, where n' is in the range from 0 to n-1, or
- (ii) a smooth roll.
