Abstract: Transmission device comprising a first rotary member mounted coaxially on a second rotary member. The first rotary member can rotate in one direction independently from the second rotary member, and in the opposite direction is constrained to the second rotary member in order to rotate solidly therewith. The device can assume a first and a second condition of use, wherein the first rotary member rotates in the two directions independently from the second rotary member, and a third condition of use wherein clamping means, integrally associated with the first rotary member, move from a position of non-interference to a constraint position wherein they constrain the second rotary member in order to make the first rotary member and the second rotary member rotationally solid.

Abstract: Device (15) to frame photographic films (18) which is suitable to divide the photographic films (18) into single photographs (19) and to insert and position the photographs (19) between two half-frames (12) forming frames (12) to hold photographs (19) and is fitted to framing machines (10), which comprise storage containers (11) to feed empty frames (12), conveyors (13-14) to convey empty frames (12) and storage bins (21) to receive the finished slide consisting of a frame (12) holding a photograph (18), the empty frames (12) arriving at the device (15) in a direction at a right angle to the direction of feed of the photographic films (18) in the device (15), which comprises in reciprocal cooperation:at least two drawing units (22) to draw the photographic film (18), each unit consisting of a powered roller (23) equipped with drawing needles (24) and an opposed roller (25) provided with a groove (26), the opposed roller (25) being movable vertically in relation to the powered roller (23),a first knife (30) wi

Abstract: Method to frame photographic films (21) which are fed to a framing station (17) in which the films (21) are divided into single photographs (22) which are inserted into empty frames (12), which arrive at the framing station (17) on a second conveyor (20) that passes in a direction at a right angle to the direction of feed of the photographic films (21), the empty frames (12) being fed to the framing station (17) as they are withdrawn from storage containers (13), the frames containing the photographs (23) being required to include written imprinted messages (19-119) before being suitably stored in final bins, the written messages (19-119) being imprinted on the empty frames (12) while the latter (12) pass along a first conveyor (15) that connects the storage containers (13) to the second conveyor (20), the first conveyor (15) passing in a direction at a right angle to the direction of feed of the second conveyor ( 20).

Abstract: A method and machine for automatically or manually mounting photographic films in predetermined lengths into mounts mechanically openable at one side. The invention includes an operative unit automatized and controlled by microprocessor for checking the film feed by monitoring notches on the film. A toothless roller system advances the film and loads it into a mount. Cooperating cutting means and opening means simplify the operation. A three-way shifter shifts the film either upwardly for storage, downwardly for disposal or may be passive in which case film proceeds to mounting.
