ABSTRACT:
In a sheet forming part2of a soft capsule manufacturing apparatus1, a drum drive system27which forms a gelatin sheet13, and a pickup roller drive system28which peels off the gelatin sheet13are constructed to drive separately from each other. In the drum drive system27, a film-sheet forming drum23is driven by a first motor271, while in the pickup-roller drive system28, a pickup roller24is driven by a second motor281. 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.
