Abstract: An apparatus for carrying out a method for inserting a slide (3) into a slide frame (10) is provided with a pusher (12) reciprocally guided in the plane (21) of the slide frame (10), a guideway (24) for the slide (3) and a knife (4) for cutting off the slide (3). For providing an apparatus of said kind of a simpler design and a faster operation, the guiding path (24) for the slide (3) extends in the plane (21) of the frame (10). The knife (4) is arranged above the plane (21) of the frame (10). By a flap (17) pivotable around a horizontal axis (19) the slide (3) can be moved completely into the plane (21) of the frame (10) after cutting (FIG. 3).

Abstract: A method for inserting slide frames (17, 21) or film strips in the pockets (10) of a two-layer film jacket (2) which is open on one side (14). The pockets (10) are partitioned from each other by transverse seams (6), preferably transverse weld seams. One or several slide frames (17, 21) are successively inserted into a pocket (10), or a film strip is inserted into a pocket (10). The film jacket (2) is then transported in the longitudinal direction (12) of the film to the next pocket (10) to be filled. In order to simplify such a method, during the further transport of the film jacket (2) for the positioning of the next pocket (10) to be filled, the position of the next transverse seam (6) is detected by a feeler (1) which is moved in between the film layers (11, 13) at the open side (14) of the film jacket (2). The feeler (1) is movable in longitudinal direction in a direction (18) parallel to the transverse weld seams (6) and is provided with a wedge surface (19) at its end moving into the film (2).

Abstract: A film jacket (1) for flat articles, particularly slide frames (5, 6, 7, 8), that consists of bottom and top plies (2, 3; 103), which are joined at one end and on both sides so that they can accommodate the slide frames. To permit the film jacket to be filled quickly and in a simple manner and to permit the slide frames to be individually taken, one film ply (3; 103) is formed with a transversely extending slit (15, 16, 17; 115, 116, 117) which is spaced from the closed end (4; 104) of the jacket by a distance (l) that corresponds to the length of one slide frame.

Abstract: A method of automatically detecting the locations of the frame lines of a reversal film as it is supplied to a processing station, such as a cutting and mounting station, a notching station or the like, so that the frame lines can be used as reference marks for the positioning of the film in the processing station wherein the film is moved past optoelectronic scanner in steps which amount to only a fractional part of the normal width of a frame line. The scanner generates an analog voltage which represents the accumulated light transmission of the film in a scanned area, which extends at right angles to the direction of travel of the film substantially across the picture area of the film and has a width which is only a fractional part of a normal width of a frame line. The extreme value of the voltage obtained during a scanning of at least one normal frame length and corresponding to the lowest light transmission is evaluated as a representation of the light transmission of the scanned film at a frame line.

Abstract: This invention relates to a device for expanding the entrance slot of a plastic slide frame having at least one resiliently expandable entrance slot, which device comprises two noses, which are arranged to engage the top surfaces of frame edge portions disposed laterally of the entrance path for the slide, and a ramp, which is spaced from said noses. In order to permit such a device to be operated without a need for a special protection against fingerprints, the device comprises a feeding pusher for pushing the slide through the expanded entrance slot.
