Claim:
A rotary die process for manufacturing capsules ( 1 ), in particular soft capsules, in which at least two material strips ( 2 , 2 ′) are brought together by means of counter-running forming rolls ( 3 , 3 ′) and formed into capsules, a filling material ( 6 ) being introduced via a filling wedge ( 4 ), which is arranged in the drawing-in region of the forming rolls, through at least one feed channel ( 5 ) between the material strips closing to form capsules, wherein between the feed channel ( 5 ) and at least one wedge surface ( 12 , 12 ′) facing the material strip, the heat transfer is reduced by a cooling medium ( 10 ), which is passed through at least one cooling channel ( 8 ) between the feed channel ( 5 ) and the wedge surface.
