Abstract

To manufacture a film unit, a filmstrip is advanced out of a cartridge shell by rotating a spool of the cartridge shell through a spool drive shaft. The spool drive shaft stops when the filmstrip is advanced a predetermined length out of the cartridge shell. A rotational position of the spool at the stop of the spool drive shaft is detected based on a rotational position of the spool drive shaft. The cartridge shell is disengaged from the spool drive shaft while the rotational position of the spool and the advanced length of the filmstrip are maintained unchanged. The spool of the cartridge shell is engaged with a film supply shaft, after adjusting a rotational position of the film supply shaft to the rotational position of the spool, while the leading end of the filmstrip is secured to a winding shaft. The filmstrip is wound into a roll by rotating the winding shaft.
