In a sheet forming part 2 of a soft capsule manufacturing apparatus 1, a drum drive system 27 which forms a gelatin sheet 13, and a pickup roller drive system 28 which peels off the gelatin sheet 13 are constructed to drive separately from each other. In the drum drive system 27, a film-sheet forming drum 23 is driven by a first motor 271, while in the pickup-roller drive system 28, a pickup roller 24 is driven by a second motor 281. The first motor and the second motor are controlled in speed separately from each other, so that the film-sheet forming drum rotates at a suitable speed for forming film sheet on the peripheral surface and the pickup roller rotates at a suitable speed for peeling off the adhered film sheet on the peripheral surface of the film-sheet forming drum, whereby gelatin sheet jamming and double-rolling on the film-sheet forming drum, which would be caused by too weak peeling force of the pickup roller, and gelatin sheet damage between the pickup roller and the film-sheet forming drum, which would be caused by too strong peeling force.
