Abstract: A transfer printing station is provided which has two pairs of tractor drives movably arranged side-by-side on two drive shafts. During operation with only a single paper web, the unused tractor drives can be moved to a lateral parking position. The two pairs of tractor drives can be easily moved to match two different webs of paper of different widths. The structure enables a user to adapt the paper conveyor of a transfer printing station to operate with only a single paper web or two parallel webs.

Abstract: A camera wherein the synchronizing switch which fires the flash unit can be moved by a first lever which gradually increases the f/stop or by a second lever which constitutes the armature of the shutter-closing electromagnet, depending upon whether the first lever reaches a predetermined position corresponding to a maximum f/stop prior to deenergization of the electromagnet or vice versa. The respective lever then moves a mobile contact of the synchronizing switch against a fixed contact. The switch is opened in response to cocking of the shutter.

Abstract: Apparatus for splicing successive exposed photographic films end-to-end by means of uniting bands one side of which is coated with hotmelt has a ribbon which is severed at regular intervals at the splicing station to yield a succession of uniting bands. Each band is caused to overlie the ends of films at the splicing station and is thereupon pressed against the films by two heated rams which move toward each other as soon as a fresh band is separated from the ribbon. The ribbon is retracted from the splicing station immediately upon severing to avoid the flow of hotmelt thereon as a result of heating action of the rams.
