Abstract: The present invention relates to an apparatus for mounting a film transparency into a slide mount to prepare a photographic slide. The apparatus is useful for preparing a photographic slide for a slide mount of the type formed of upper and lower frame sections connected along an outer border to define a pocket therebetween. The slide mount also includes a slit adjacent to the outer border to separate the upper and lower frame sections to define a first insertion opening adjacent to the slit and a second insertion opening into the pocket of the slide mount. Cooperating film guides are positioned adjacent to the second insertion opening to guide a leading edge of the film transparency, which is inserted into the pocket of the slide mount, through the second insertion opening of the slide mount.

Abstract: The present invention relates to a semi-automatic slide mounter where individual film transparencies are severed from a photographic film and inserted into a slide mount to prepare a photographic slide. In the semi-automatic slide mounter, a portion of the operation of the mounter is controlled by a manual operating lever and a portion is controlled by a motorized drive assembly. In particular, the film web is advanced along a film track for operation by the motorized drive assembly and individual film transparencies thereof are severed by a knife assembly and inserted into a slide mount ejected from a slide magazine. In the apparatus of the present invention a latch assembly is coupled with the manual operating lever to restrict operation of the manual operating lever while the film is advanced by the motorized drive assembly.

Abstract: The present invention relates to an apparatus for advancing a photographic film web for operation in a semi-automatic or automatic slide mounter. The apparatus advances the film for operation across a knife assembly to position the film with upper and lower knife blades of the knife assembly to sever a film transparency from the photographic film web to prepare a photographic slide. The apparatus includes a shuttle bridging mechanism for supporting the film, movable between a retracted position, out of alignment with the knife blades and an advanced position, extending across a support gap defined at the upper and lower knife blades. The shuttle bridging mechanism is advanced during operation to the advanced position and the film is advanced until a trailing edge of a leading film transparency aligns with the upper and lower knife blades.

Abstract: Automatic and semi-automatic slide mounters sever individual film transparencies from a photographic film web to prepare photographic slides therefor. The present invention relates to an apparatus for severing the individual film transparencies from the photographic film web in a slide mounter. The apparatus includes a movable knife assembly adapted for longitudinal adjustment and having a gauge for establishing an adjusted position for upper and lower knife blades therefor. The movable knife assembly is adjusted prior to operation to assure that the individual film transparencies of the film web will be correctly severed along film frame delineations for the individual film transparencies when advanced for operation across upper and lower knife blades of the knife assembly.

Abstract: Method to prepare a leading edge of a photographic film for framing, the leading edge (13) of the photographic film (11) being sheared at an angle (18) to the direction of feed (15) of the film (11) in a frame (12).Device to frame a photographic film (11) in frames (12), which employs the above method and comprises an assembly able to shear at an angle (18) the leading edge (13) of the photographic film (11).Photographic film (11) prepared with the above device and comprising a leading edge (13) sheared at an angle (18) to the direction of feed (15) within the frame (12).

Abstract: An apparatus for cutting a used ink ribbon wound in a pancake form, comprising a ribbon holder for setting a position of the ink ribbon, and a plurality of cutting blades extending radially on one surface of a base member movable relative to the ink ribbon. When the base member is driven to the ink ribbon, the cutting blades cut the ink ribbon through a plurality of cutting planes extending radially from the axis of the ink ribbon in a pancake form.

Abstract: There is provided an apparatus for supplying precisely measured lengths of leader ribbon for use in the assembly of printer ribbon cartridges. The apparatus includes a supply of leader ribbon, an accumulator for retaining a length of the ribbon when it is drawn from the ribbon supply and a drive assembly for drawing a measured length into the accumulator. The drive assembly includes a fixed roller and a pivotable roller positioned on opposite sides of the ribbon path for engaging the ribbon therebetween. A stepping motor is provided for rotating the rollers a prescribed number of revolutions and thereby stuffing a measured length of the engaged ribbon into the accumulator. The apparatus also includes a cutter for severing the measured leader length from the supply ribbon.
