Description

The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 2.

A method and an apparatus of this type are known from US Pat. No. 3,194,709.

A disadvantage of this known method is that to cut out a slide film piece, the slide strip is bent in a guide and cut in the bent state. In addition, slide masks that can be folded around a bending edge are used, which have to be glued by applying heat and pressure after inserting a slide film piece.

Another method and a device of the type described in the opening paragraph are known from DE-OS 1 572 723.

It is disadvantageous in the practice of that method or in the handling of that device that the cutting out of a slide film piece to be framed from the developed slide strip is time-consuming and tiring because the slide framing width must be adhered to precisely, which is particularly important for high concentration for the second cut, if a transverse side has already been trimmed and the film strip is pushed under the cutting knife on its second transverse side to separate the film piece. It is also disadvantageous that cut-out slide film pieces, which should not be framed at all, and in particular also strip-shaped cut waste when making correction cuts due to incisions which were initially not made to size, fall on the lower frame provided for receiving the cut slide film piece and there subsequently result in malfunctions lead because the removal of this waste waste is not easy - especially since it is a subframe with adhesive adhesion points for filling material. Finally, it is a disadvantage of the known device for practicing the known method that only special frames with pressure-sensitive adhesive points can be used to fix the inserted, cut slide film piece on the lower frame, while the lower frame is moved together with the film piece into one position, in which a top frame is applied. This transfer of the assembled sub-frame into a position in which the upper frame can be accommodated also requires considerable outlay on equipment not only for the dimensionally fitting press of the cut slide film piece onto the pressure-sensitive adhesive point, but also for the further movement of the assembled sub-frame in a position that is coordinated with the advance of an upper frame.

For a device of a different type, namely for a device for loading punch cards with microfilms, it is known to cut out the desired microfilm image from a film spool and to stick it over a window in the punch card, for which purpose a frame-shaped stamp with an external cross section according to the dimensions of the individual image is attached two sides assigned to the film piece transverse sides are equipped with cutting edges. During the cutting process, the film strip runs through mutually opposing grooves. In the course of the cutting process, these grooves are pressed apart so that the front edge of the frame-shaped stamp can push the cut-out film piece out towards the front and press it against the glued area on the edge of the window opening in the punch card arranged in front of it.

A disadvantage of this arrangement is, in particular, the design effort for the design of the cutting and pressing device, taking into account the release of the cut film piece from the film strip guide; and it is furthermore disadvantageous that the danger is very great that the cut-out piece of film will be pushed out of the guide grooves so that the piece of film is glued to the opening in the punched card in a twisted manner.

Finally, a complicatedly constructed slide framing device is known (FR-PS 2 168 816), in which cut-out slide film pieces are also inserted into a snap frame which is glued after being inserted under pressure and heat. In this device, it is also known to use an inclined transfer plane for transporting the finished-framed slides, which ends in a collecting shaft for the finished-framed slides.

Recognizing the fact that the photo amateur who wants to frame his slides worth storing, does not need a machine that can be used commercially and / or can be operated automatically, but an easy-to-use cutting and framing device that is better on film protection than conventional viewing and cutting devices for amateur use provides, after which the slide film piece must be clamped by hand in the frame, the invention has for its object to provide the method or the device of the type mentioned in such a way that a selected slide correctly cut and easy handling without the need to use special frames and in particular adhesive frames, can be clamped correctly between the upper and lower frames of the slide frame in a reliable manner.

This object is achieved in a method according to the preamble of claim 1 solved by that it is designed according to the characterizing part of claim 1, and in a device according to the preamble of claim 2 in that it is designed according to the characterizing part of claim 2.

In contrast to the possibilities that the generic device opens up, according to the solution according to the invention - as known in other fields, information technology, as such - the slide film piece to be framed is achieved directly in the correct framing width and essentially in free fall by means of a single cutting movement , so without the need for any mechanical aids, in a subframe. Since the lower frame between the template for receiving the cut slide film piece and the placing of the upper frame is not — especially not with the film piece — movable, there is no need for a connection between the film piece and the lower frame for the final framing process and therefore also any risk of being inaccurate aligned position of the slide film piece in the lower frame. Malfunctions due to cutting waste are not to be feared, since only the slide film piece to be framed lies between the two knives of the cutting device, whereas an edge strip that occurs outside the area between the knives can be prevented from falling into the area by simple shielding measures , in which the cut piece of film is transferred to the lower frame.

The funnel-like function of the drop and straightening shaft as an alignment element for the last stretch of free fall of the cut slide film piece into the lower frame is further promoted if the further education measure is taken according to claim 3, by which tilting and thus setting up the Film piece on the lower frame is securely prevented.

The additional measure according to claim 4 promotes the placing of the upper frame onto the lower frame equipped with the film piece, in which the mechanical measures for feeding the upper frame can be designed independently of the transfer of the film piece. Above all, however, this solution opens up the possibility of taking the further education measure according to claim 5, in which the shaft dimensioned in the internal cross section for the cut slide film piece is moved aside if slide frames are used in which the upper frame does not have the same dimensions, like the slide film piece itself.

The submission of lower and upper frames and, if necessary, the movement of the drop and straightening shaft for the film piece can be realized in a particularly functional and at the same time structurally inexpensive manner in accordance with the further training measures according to claim 6, for the lower frames and upper frames. Submission of opposite movements, controlled by the pendulum movement of a single cross-loop carriage.

The slide frames for amateur use that are most frequently found on the market are of the same size, and the lower frames and upper frames can be connected to one another in a positive and non-positive manner in the vicinity of the film window using profiles that are oriented transversely to their main levels in the manner of tongue and groove. In this case, it is expedient to combine the functions of the lever device for the drop and straightening shaft and of the closing device for connecting the upper frame and lower frame with the film piece being interposed, in accordance with the development according to claim 7, in terms of equipment and function, because this results in a results in particularly little complex construction with high functional reliability.

Particularly in the case of these slide frames, in which the upper frame has the same format as the cut slide film piece, it is expedient to provide a stationary drop and straightening shaft and, after inserting the film piece into the lower frame, in the same way to align the above to be discarded upper frame.

Closing pressure claws coordinated with the frame movement according to claim 8 can be provided alone or in addition to impact or pressure roller devices for connecting movable upper and lower frames.

In the case of non-two-part slide frames in the sense of the present invention, the film recording depression has the function of the lower frame to be fitted and a holding part rigidly attached or articulated thereon has the function of the upper frame. In the case of commercially available one-piece slide frames, the upper frames are attached to the lower frames with hinges. These can also be equipped according to the invention by making changes in the sense of the teaching according to claim 9 only in the area of the slide frame magazine.

The subject of claim 10 is the application of the invention to commercially available one-piece slide frames, as described in DE-AS 25 16 493.

The cutting tool design according to claim 11 is characterized in particular by being able to keep the overall height of the device low, which favors its handling when set up on a table. A further ease of operation is given by the fact that two-handed operation is made possible, for example by the user moving the film through the left hand Viewing zone and, when a framed slide is reached, right next to it on the side of the device, the actuation button for the knives is pressed, while the other hand on the opposite side of the device is available to make one revolution of the crank drive for one cycle after each cutting process to complete the framing process with the output of the framed slide.

1 shows the view of a hand-operated automatic slide cutting and framing machine 1 according to the invention in accordance with a functional model, with the hood removed for holding a viewing lens and for covering a film feed device 2. A film strip 3 can be inserted laterally into a film strip inlet viewing zone 4, the length of which corresponds to a multiple of the standardized slide framing width, so that several slides can be viewed side by side on the film strip 3 which has not yet been cut.

In the interior of the housing 5, a lamp 7 (cf. FIG. 2) fed via a mains cable 6 is arranged, which illuminates the film strip 3 from below through a diffusely scattering disc 8, which extends from above, through the stretched along the viewing zone 4 Lens 9 (see FIG. 2) can be viewed. 1, the film strip inlet viewing zone 4 need not extend in one plane parallel to the base 10 of the housing 5. Rather, when the film plane is arranged in an inclined manner in viewing zone 4, viewing is made easier device of the slides contained side by side on the film strip 3. The slide film strip 3 is advanced through the film strip inlet zone 4 through mutually opposite and open film strip guide grooves 11. As long as the film strip 3 still protrudes beyond the beginning of the viewing zone 4, it can be pushed forward by hand. A sensitive feed as well as a gentle feed with short film strip ends takes place by means of the film strip feed device 2. In the functional model shown, this consists of a handwheel 12 (see FIG. 1) for driving a shaft 13 (see FIG. 2) on the area a small pressure and transport wheel 14 (see FIG. 3) is arranged in the adjacent film strip guide groove 11. This is pressed by means of a spring 15, in the functional model by means of a tension spring via a rocker 16, through a recess 17 in the upper flange of the guide groove 11 against the lower flange and thus against the perforated edge region of a film strip 3 inserted between the guide grooves 11. Via a gear 18, in the example shown a transmission coupling to further shafts 13, further pressure and transport wheels 14 arranged in the same way are driven in the same direction by the handwheel 12. Contrary to the representation of a simple functional pattern, it may be expedient to provide a deflection gear between the handwheel 12 and the shafts 13 in such a way that a rotational movement in the same direction on the periphery of the handwheel 12 protruding from the housing 5 is required for advancing the filmstrip 3.

Above the guide grooves 11 for the film strip 3, mounting grooves 19 of larger dimensions are arranged, which are dimensioned for receiving frames with already framed slides 65 in order to illuminate them from below through the lens 8 and from above through the magnifying lens 9 to be able to consider.

In order to ensure a flat alignment of the film strip 3 under the lens 9 over as far as possible the entire film strip inlet viewing zone 4 and also to be able to output short pieces of film strip, for example slides already cut to the frame width, from the viewing zone 4 and to transfer them into the cutting zone 20 immediately adjacent thereto. a shaft 13 with pressure and transport wheel 14 of the type described is arranged immediately before the transition from the viewing zone 4 to the cutting zone 20 and in the cutting zone 20. A coupling gear 18 also acts between these shafts 13, for example again from transmission belts 21 via pulleys 22.

The length of the cutting zone 20, measured in the direction of the advance of the film strip 3, and thus the distance 23 (FIG. 4) between the counter knives 28 is fixed by spacer sleeves 25 and corresponds to the standardized framing width of a film strip which has been cut and inserted into a frame 3 cut slides. To change to other framing widths, therefore, only other spacer sleeves 25, 25 'need to be used for spacing the fixed knives 28; 4 corresponds to the smallest occurring framing width, to which the operating parts between the movable knives 24, which will be described in more detail below, are matched and which therefore do not need to undergo any change for the transition to longer spacer sleeves 25.

Each knife 24 is designed as a one-armed lever and is mounted opposite the operating handle 26 common to both knives 24 on a pivot axis 27 fixed to the housing. To cut out a slide film piece from the film strip 3, each knife 24 exerts a scissor-cutting effect on the latter by each knife 24 cooperating with its fixed counter knife 28, the cutting edge of which in front of the associated outlet opening 29 of the film strip guide grooves 11 in the region of the viewing zone 4 or in the region of the cutting zone 20 in the central plane through the guide grooves 11. To ensure the scissors-cutting action, the knives 24 arranged inside the counter-knives 29 have a slight reworking in the folded-up position in the sense of an employment, so that under the spreading influence of compression springs 30 on the spacer sleeves 25 'when the free ends 31 of the knives are pressed down 24 by means of the operating handle 26 results in a secure cutting action on the film strip 3 which progresses along the knives 24/28 from the pivot axis 27 fixed to the housing.

Since the slide film piece to be framed, that is to say the image located in the cutting zone 20, is of particular interest to the user and must be aligned exactly between the knives 24, it is of particular practical importance that the lamp 7 is not covered by structural parts for the framing process .

As the operating handle 26 for the cutting process for removing a slide film piece with a frame width from the film strip 3, a block to be actuated as a push button is provided in the functional model shown in the drawing, which block is articulated in the region of the free ends 31 with the pivotable upper knives 24 is connected by pressing against the spacer sleeve 25 'arranged between these free ends 31. Compared to the spacer sleeve 25 between the adjacent ends of the fixed counter knife 28, this block undergoes a parallelogram slot guide 32 in order to avoid a shift pivot this block serving as a handle 26 to prevent during the exercise of the cutting process (pressure movement according to the arrow 33 in FIG. 1 or FIG. 5). As can be seen from FIG. 5, the return movement of the upper knives 24 after the cutting movement has been carried out is in each case a return spring 34, for example a tension spring anchored to the housing.

The slide film piece 35 (see FIG. 5) cut out and to be framed with the framing width from the film strip 3 (see FIG. 2) is moved between the fixed lower counter knives 28 in the course of the lowering of the upper, movable knives 24. by passing it down into a transfer zone 36, while the waste waste 37 (cf. FIG. 2) which occurs in front of the front transverse side of the slide film piece 35 comes to lie beyond the associated counter knife 28. Below the upper or cutting edge 38 of this counter knife 28 begins a slightly downwardly inclined discharge plane 39 for the removal of the waste waste 37, which thus does not interfere with the further treatment of the slide film piece 35 to be framed.

In the functional model shown in detail in the drawing, cf. 2 and 6 in particular, the transfer zone 36 is formed overall as an inclined plane 40 which begins in the region of the transition from the viewing zone 4 to the cutting zone 20 below the film strip guide grooves 11 and is inclined much more sharply than the discharge plane 39. The inclined plane 40 expediently adjoins the knife-side end 41 of the diffusely scattering disc 8 and advantageously in turn consists of a diffusion disc 42, through which the area of the film strip 3 is illuminated from below and can be viewed from above, which can be seen in FIG Cutting zone 20 is located. The elongated lens 9 also preferably extends beyond the viewing zone 4 in order to still also capture the cutting zone 20, cf. 2 or 6.

In order to be able to eject the slide film piece 35 cut out of the film strip 3 from the cutting zone 20 to separate it from the waste waste 37, the lower flanges 43 of the film strip guide grooves 11, insofar as they are located in the cutting zone 20, are laterally as surfaces fold-down support claws 44 are formed, cf. 5. These support claws 44, which are drawn out in FIG. 5 in the rest position, namely when the upper knives 24 are raised, and are shown in dash-dot lines in the folded-down position, are in the region of the holder 45 for the lower counter knives 28 each against a pin 46 against the Restoring force of a return spring (not shown in the drawing) is pivotally mounted. The defined rest position in relation to the upper flange 47 is served by a stop 48 projecting downward from this on one longitudinal side of the cutting zone 20 and the outer surface of the pressure and transport wheel 14 in the region of the opposite guide groove 11. For this reason (see FIG 2) this pressure and transport wheel 14, which is located in the region of the cutting zone 20, not to be under the influence of a rocker 16 or the like pressure device acted upon by a spring.

To fold away the lower flanges 43 in the form of the support claws 44, in the course of the cutting process when the upper knives 24 sink, their cutting edges 49 come up against stops 50 (cf. FIGS. 4 and 5) which protrude laterally from the support claws 44. After a short cut in the area of the perforation of the long side of the film strip 3, which is located towards the knife pivot axis 27, this film strip guide groove 11 is first opened by lowering the lower flange 43 by folding down the support claw 44 from the periphery of the pressure wheel 14 Due to the leverage, the lifting of the clamping bracket under the pressure wheel 14 by folding down the associated support claw 44 takes place more quickly than the progress of the cut when the upper knife 24 is pressed down. As a result, there are two exactly parallel, linear cuts running transversely to the longitudinal extension of the film strip 3 on both sides the framing width of the slide film piece 35 to be removed is ensured, which in its already separated area is bent downwards by the cutting edges 49 of the upper knives 24 arranged within the counter knives 28. When approximately half the cut has been made, at least before the completion of the complete removal operation, the opposite support claw 44 is also folded down laterally via its stop 50 from an upper knife cutting edge 49, so that the slide film piece cut to frame size over the length of the cutting zone 20 35 is transferred in the undisturbed free fall to the transfer zone 36 beginning under the cutting zone 20.

In the case of the realization of the transfer zone 36 as a snowing plane 40, this slide film piece 35, which is now to be framed, is conveyed downwards due to its gravity. So that there is no electrostatic charge and the resulting tendency to stick, the surface of the inclined plane 40 is expediently covered in the longitudinal direction with strips 51 made of electrically conductive material (see FIGS. 2 and 6), for example by applied conductive lacquer or by glued-on metal wires can be realized.

The free discharge end 52 of the inclined plane 40 transfers the slide film piece 35 into a fall and straightening shaft 53, the side walls 54 of which are slightly inclined in order to achieve a slightly decreasing cross-section of the shaft 53, which is slightly downward and is above its Bottom 55 corresponds to the cross-sectional shape of the cut slide film piece 35 to be framed. Under the lower edge 56 of the shaft side walls 54, a slide subframe 57 of a two-part slide frame with an upwardly facing film receiving depression 58 (see FIG. 2) is arranged on the shaft bottom 55.

The inclined plane 40 protrudes with its free transfer end 52 over the adjacent side wall 54 into the chute 53, but only so far that the outer surface of a cylinder 59 (cf. FIG. 2) concentrically with the diagonally opposite lower edge 56 ' not cut from the inclined plane 40 or even touched. In this way it is ensured that the slide with its downward, that is to say forward in the transfer movement direction, front transverse side along the diagonally opposite lower edge 56 'or in its immediate hubs against the side wall 54', and / or the lower frame 57 on the shaft Floor 55, strikes and, possibly guided by the opposite side wall 54, which is adjacent to the inclined plane 40, finally falls exactly into the film receiving depression 58.

As can be seen from FIG. 6, upper frames 61 are stacked in an upper magazine 60, which, in order to fix the slide film piece 35 in the lower frame 57, are pressed into the film receiving depression 58 thereof and are thereby anchored therein in a form-fitting and / or non-positive manner. After a slide film piece 35 has been placed in the lower frame depression 58, the lowest of the upper frames 61 held in the upper magazine 60, preferably transversely to the transfer direction of the slide film piece 35, is pushed out into the drop and straightening shaft 53, which is in similarly, as previously described for the slide film 35, centered between the inclined side walls 54 to drop into the depression 58.

To press the upper frame 61 into the depression 58, the lower frame 57 equipped with slide film piece 35 and upper frame 61, for example, can be passed through a frame locking device 64, symbolically shown in FIG. 6 as a pressure roller arrangement 63, in the course of the transfer into an output zone 62 . Another type of locking device is explained below in connection with FIG. 7.

The framed slide 65 is fed out by presenting a further lower frame 57 from a lower magazine 66 at the level of the shaft bottom 55, that is to say below the output plane of the upper frame 61 from the upper magazine 60. For this purpose, the lowest lower frame 57 of the one in the lower magazine 66 is arranged Stack against the extension direction of the upper frame 61, i.e. also transversely to the transfer direction of the slide film piece 35, pushed under the lower edge 56 of the shaft side walls 54 to also in its film recording depression 58 with a slide film piece 35 and then with a top - frame 61 to be equipped.

As the drive for the coordinated subframe 57 and upper frame 61 and possibly for the operation of a frame locking device 64, a crank mechanism is preferably selected, which is designed as a cross-loop crank mechanism 67 in the functional model described in accordance with the perspective schematic illustration in FIG. 7. Its crank disk 68 is equipped with a rotary handle 69, which is shown in FIG. 7 as a hand crank and in FIG. 1 as a handwheel. For fixing in a basic position as the initial position of the movement cycle, a latching roller 70, which is resiliently supported against the periphery of the crank disk 68, engages in a latching notch 71 in the periphery of the crank disk 68 when the basic position is reached.

The crank disk 68, via its sliding block 72, sets a linearly guided slide 74 in a reciprocating movement in the course of one revolution of the crank disk 68 in its loop slide path 73. This movement and thus the slide guide 75 takes place perpendicular to the extension of the loop slide track 73. Lower magazine ramp slides 76 are fastened to the slide 74 approximately in the plane of the slide guide 75 and in a plane arranged above the upper magazine ramp slide 77. The lower magazine ramp slides 76 serve to engage in the lower region of the lower magazine 66 (cf. FIG. 6) for advancing the lowest of the lower frames 57 stacked therein under the shaft 53. The lower magazine ramp slides 76 are rigidly connected to the slide 74.

The upper magazine ramp slide 77 are in the basic position of the crank disk 68, that is to say when the lower magazine ramp slide 76 are advanced, out of engagement with the upper magazine 60. Because the slide 74 is arranged below the plane of the shaft bottom 55, the lower end of the upper magazine 60 but is significantly higher, the upper magazine ramp slides 77 are articulatedly connected to the slide 74 to avoid tilting and are guided in their plane of movement in a bracket guide 78 parallel to the slide guide 75.

In the basic position of the crank disk 68, that is to say with the slide 74 advanced and the upper magazine ramp slides 77 pushed back, the sliding block 72 is located in the middle of the loop slide track 73 and thus at a dead center of movement with respect to the oscillating movement of the slide 74 when the movement rotates Crank disk 68. In the course of the first half rotation of the crank disk 68, the lower magazine ramp slides 76 are pulled back under the lowermost lower frame 57 behind its rear edge, while the upper magazine ramp slide 77 is pushed along with the bottom upper frame 61 in the upper magazine 60 in order to transfer this upper frame 61, as described in connection with FIG. 6, into the drop and straightening shaft 53. After the upper frame 61 has been pushed out of the upper magazine 60, but before reaching the second dead center of the movement of the slide 74 associated with half a revolution of the crank disk 68, the frame closing device 64 'is actuated. In the functional model according to FIG. 7, this consists of pressure claws 79 which are arranged in the region of the lower edge 56 outside the side walls 54 of the drop and straightening shaft 53. The pressure claws 79 can be pivoted against the force of a return spring (not shown in the drawing) about pivot axes 80 running parallel to the lower edges 56 such that they pivot into the interior of the shaft 53 through openings in the side walls 54 (see FIG. 9) can and with their free ends can exert pressure on the edge region of the upper frame 61 in order to press it into the depression in the lower frame 57 and thereby anchor it therein.

To perform this pivoting movement, each pressure claw 79 is designed as a two-armed lever, the actuating arm 81 of which extends in the plane of the slide guide 75 and thus below the shaft bottom 55. The actuating arms 81 have angled ends 82. In the preferred implementation example according to FIG. 7, two actuating arms 81 assigned to a shaft side wall 54 are connected to one another in a bow shape via their angled ends 82.

A double-inclined expanding wedge 84 is pivotally connected to the slide 74 via a drawbar 83. Before the carriage 74 has reached its retracted dead center of movement, inclined spreading surfaces 85 of the spreading wedge 84 come into engagement with the angled ends 82 of the pressure claw pairs 79-79 arranged on both sides of the feed path of the spreading wedge 84. After the upper magazine ramp slides 77 have transferred an upper frame into the shaft 53, this results in the pressure claws 79 pivoting sideways into the shaft 53 through the shaft side walls 54. The inclined spreading surfaces 85 have a strong inclination with respect to the longitudinal movement direction of the spreading wedge 84 to cause the pressure claws 79 to swivel in rapidly, although shortly before the second dead center of movement, the sinusoidal movement profile of the slide 74 is only slowly retracted in relation to the rotary movement of the crank disk 68.

The strongly inclined spreading surfaces 85 merge on the spreading wedge 84 into weakly inclined spreading surfaces 86 in order to apply correspondingly strong pressure to the now extremely slow forward movement of the spreading wedge 84 in the region of the second dead center of movement (in the region of half a turn relative to the basic position of the crank disk 68) Exercise actuating arms 81 and thus over the actuating ends of the pressure claws 79 on the upper frame 61 on the bottom 55 of the shaft 53. Thereafter, the upper frame 61 and the lower frame 57 are connected with a slide film piece 35 arranged therebetween to form the framed slide 65. In the course of the further rotation of the crank disk 68, the expansion wedge 84 is pushed back again, i. H. the pressure claws 79 lift off from the edge region of the upper frame 61 in order to pivot out of the shaft 53. As the slide 74 advances during this second half rotation of the crank disk 68, the upper magazine ramp slides 77 retract under the lowermost upper frame 61 in the upper magazine 60 to behind the rear edge thereof, while at the same time the lowermost lower frame 57 in the lower magazine 66 under the shaft 53 is presented and thereby transfers the framed slide 65 into the output zone 62, where it is ejected or can be removed.

To operate the automatic slitting and framing machine 1 according to the invention (cf. FIG. 1), it is therefore only necessary to fill the sub-magazine 66 with subframe 57, to make a rotation on the turning handle 69 under the slot 53 to present the first subframe 57 to fill the upper magazine 60 with upper frame 61 and henceforth only ever make one rotation on the rotary handle 69 after the cutting handle 26 has been actuated once in the cutting zone 20 when a slide to be framed appears on the film strip 3. The magazines 60, 66 and the shaft 53 are expediently covered by a transparent hood 87 on the housing 5 in order to keep the stock of lower and upper frames 57 and 61 and the proper incidence of the slide film piece 35 cut out of the film strip 3 in to be able to visually monitor the subframe 57. The removal plane 39 for waste waste 37 (cf. FIG. 2) is preferably formed on the transparent hood 87 (cf. FIG. 1) itself in order, in view of the illuminated diffusing screen 42, which the inclined plane 40 for transferring the cut slide film piece 35 represents to be able to clearly recognize and remove even the smallest pieces of waste waste 37.

The arrangement of the crank disk 68 according to FIG. 7, that is to say with a loop slideway 73 oriented rigidly on the slide 74 and oriented perpendicular to the oscillating movement of the cross-loop slide 74 and perpendicular to the plane of the shaft bottom 55 (see FIG. 6) comparatively large overall height of the automatic slide cutting and framing machine 1 (see FIG. 1). In the interest of lower overall height, at Ensuring the same stroke for the ramp slide 76, 77 and the double-inclined expansion wedge 84, in the modified embodiment shown in FIG. 8 for the same transmission solution, the slide guide 75 extends from the free end of the framing zone 88 into the area of the connection of the framing zone 88 the transfer zone 36 (see also FIG. 9) relocated. The crank disk 68 is no longer perpendicular to the plane and extent of the cutting zone 20 in the region of the end wall 89 of the housing 5 (cf. FIG. 1), but is parallel to the plane of the cutting zone 20 below the transfer zone 36. The one with the slide 74 rigidly coupled loop slideway 73 for the sliding block 72 lies approximately in the plane of movement of the lower magazine ramp slide 76 and thus in the region of the plane through the shaft bottom 55.

In the modified implementation example according to FIG. 8, a hand crank is provided as the turning handle 69, the turning rod 90 of which runs above the crank disk 68 and parallel to the slide guide 75, i.e. out of the housing 5 next to the dispensing zone 62 (see FIG. 1; not taken into account there ) exit. The crank disk 68 is rotated by means of the rotating rod 90 via a worm gear 91. The remaining structure of the gearbox for the framing process has not changed compared to that of FIG. 7 in the modification according to FIG. 8. In particular, the plane through the pressure claw swiveling axes 80 is again in or approximately in the plane of the movement of the lower magazine ramp slide 76, that is to say just below the plane of the shaft bottom 55. The plane of movement of the double, which is pivotable relative to the feed movement on the slide-fixed drawbar 83 -Spreading wedge 84 lies for engagement against the angled ends 82 of the pressure claw actuating arms 81 slightly below that level, so that first the strongly inclined spreading surfaces 85 and then the slightly inclined spreading surfaces 86 press apart the opposite, angled actuating arm ends 82 and thereby the two-armed Swivel the lever with the pressure claws 79 formed opposite it about the axes 80. In the rest position, the actuating arms 81 rest against the shaft bottom 55 from below, so that the short angled ends 82 project vertically or approximately perpendicularly downward therefrom; in the course of the pivoting about the axes 80, the expanding wedge 84 then attacks the actuating arms 81 which then protrude at an angle relative to the shaft bottom 55 in order to exert pressure via the claws 79.

The plane of movement of the upper magazine ramp slide 77, which is connected to the latter via a spacer 92 protruding from the slide 74, is substantially higher than the plane of movement of the lower magazine ramp slide 76. Since, due to the unfavorable transfer of force via the protruding spacer 92, canting and operating malfunctions can easily occur in that much higher level, a holding bracket 93 for the upper magazine ramp slide 77 is connected via a joint 94 to the upper end of the protruding spacer 92. The housing-fixed bracket guide 78, which is aligned parallel to the slide movement, is expediently carried out directly in the base plate 95 of the slide frame upper magazine 60, cf. 6 for the gear position according to FIG. 7 or FIG. 8.

The arrangement of a lying crank disk 68 according to FIG. 8 also enables a functional locking between the actuation of the cutting handle 26 and the operation of the turning handle 69 in a particularly simple and functionally reliable manner. About the cutting process, that is to say the pressing down of the upper knives 24 (cf. FIG. 6) only to be possible if the cross-loop crank mechanism 67 is in its basic position, that is to say a lower frame 57 is pushed under the shaft 53 (cf. FIG. 6), the crank disk 68 has a recess 96, which is so arranged and dimensioned that a stylus 97 can only engage in this recess 96 when the knives 24 are operated in this basic position. If the crank disk 68 is not in its basic position, that is to say the recess 96 is not arranged below the stylus 97, a complete cutting movement with the knives 24 is not possible, and therefore a slide film piece 35 is not output from the cutting zone 20. This is avoided that without a subframe 57 placed under the shaft 53, a frame film piece 35 cut to size and ready for framing falls onto the bottom 55 of the shaft and is damaged there when a subframe 57 is inserted later or leads to signs of jamming and malfunctions.

On the other hand, this additional measure ensures that the crank disk 68 is only rotated out of its basic position and thus an upper frame 61 the shaft only when the cutting movement with the blades 24 raised again, ie when sufficient time has passed for the transfer of the cut slide film piece 35, has passed 53 can be refilled.

As already mentioned in connection with the explanation of the modified implementation in terms of transmission technology according to FIG. 8, this results in the possibility of a noticeable reduction in the overall height of the automatic slide cutting and framing machine 1. However, when the transfer zone 36 is implemented, an inclined transfer plane 40 (cf. FIG . 2) still a comparatively large and geared now technically no longer required. In the interest of easier viewing of the film strip inlet viewing zone 4, even without this being inclined towards the viewer and operator, it is expedient, in accordance with the modification outlined in FIG. 9, to provide a diffusing screen 42 'for the formation of the transfer zone 36, which is essentially parallel to the plane through the guide grooves 11. A comparison of the arrangement according to FIG. 9 with the arrangement according to FIG. 2 shows without further ado that this results in a noticeable reduction in overall height. However, an additional feed tool is required for the transfer movement of the slide film piece 35 cut to size, ready for framing, along the transfer zone 36 into the framing zone 88, which in the implementation example according to FIG. 8 / FIG. 9 is designed as a feed pin 98. This is fastened to a slide 99 in a guide 100 fixed to the device, and with its free end 101 it reaches through a slot 102 in the lens 42 'and a connecting wall 103 to the viewing zone lens 8, around that on the transfer lens 42 'put slide film piece 35 into the shaft 53.

Advantageously, the feed pin 98 or its slide 99 is under the influence of a feed spring 104 which, when the crank disk 68 is screwed into its basic position and the feed pin 98 is returned to its starting position (see FIG. 8 or FIG. 9), held tensioned and locked and after completion of the cutting process in the cutting zone 20 is released in order to set the feed pin 98 in the feed movement. For this purpose, on the one hand a device-fixed and on the other hand sled-fixed latching pawl 105 is provided, which is arranged so that it is released to release the feed movement of the feed pin 98 when, with the discharge of the slide film piece 35 from the cutting zone 20, which into the crank disk Recess 96 engaging stylus 97 is completely lowered and thereby actuates the positive release mechanism of the pawl 105. As a result, the action of the feed pin 98 is coordinated with the alternate locking between the cutting handle 26 and the turning handle 69, incorrect operations cannot occur despite the additional moving part, the movement of which has to take place between the cutting process and the framing process.

To re-tension the feed spring 104, in the implementation example according to the schematic diagram in FIG. 8, a push arm 106 or a push arm 106 or

107 rigidly attached. In the course of the forward movement of the cross-loop slide 74 for presenting a new subframe 57 under the shaft 53, tension is exerted on the feed spring 104 via these push arms 106, 107 in order to allow the detent pawl 105 to engage again immediately before the new crank disk basic position is reached. 8, a double-armed lever 108 with a thrust joint 109 to the cross-grinding carriage 74 and with a support roller 110 to the feed pin carriage 99 is provided for this thrust transmission.

It may be expedient, contrary to the basic illustration according to FIG. 8 / FIG. 9 do not provide a linear feed pin guide 100, but to use the angled end of a spiral feed spring 104 as feed pin 98, which executes an arc-shaped movement in a plane parallel to the transfer lens 42 'and, for example, by pivoting a spiral spring fastening shaft (in the Drawing not taken into account).

In particular, if the transmission for performing the Rahmungsvorganges _(t corresponds to, for example, Fig. 1 or Fig. 7) is not arranged on the housing end wall 89, but as shown in FIG. 8 / Fig. 9 in the area of the cutting zone 20 and / or the film strip inlet viewing zone 4, it is expedient to design the upper and lower magazines 60/66 with the drop and straightening shaft 53 arranged therebetween as an interchangeable device-technical unit, for example along a parting plane 11 (cf. FIG. 3; also entered in FIG. 1 to facilitate the overview) can be removed and exchanged from the other automatic slide cutting and framing machine 1 according to the invention. This makes it possible to process different slide frames for the framing process with the same basic unit.

In Fig. 10 the arrangement of a drop and straightening shaft 53 for slide film pieces 35 is shown in a sectional view parallel to the parting plane 1 1 1 for the case that the upper frame (61 in Fig. 3) does not have the dimensions of the slide film piece 35, but is significantly larger or even corresponds in size to those of the subframe 57. In this case, the film piece shaft 53 is mounted in a hinged hinge 112 along its lower side wall edge 56 ′ diagonally opposite the transfer end 52. Depending on the advance of the upper magazine ramp slide 77 (see, for example, FIG. 7), the cross-grinding slide 74 exerts force on a tilt bracket 113 and the shaft 53 through a corresponding opening 114 in an adjacent side wall 115 of a film of this type. Swing out shaft 53 surrounding larger frame shaft 116, so that the upper frame 61 'is then transferred directly into this larger drop and straightening shaft 116. When the cross-loop carriage 74 moves back into its basic position Folding back the film shaft 53 into the larger frame shaft 116, into the starting position shown in FIG. 10.

If one-piece frames are to be used for framing the slide film pieces 35 cut to size, in which the upper frame 61 "is articulated along one edge via a hinge connection 117 to the lower frame 57 ', only a single frame magazine 118 is required this one-piece frame under the frame shaft 116, which, depending on the dimensioning of the film recording depression 58, also acts as a drop and direction shaft 53 for the slide film piece 35 or is designed as a two-format folding shaft in accordance with the measure in FIG. 10, In the course of pushing a frame out of the lower end of the frame magazine 118 with a hinge connection 117 located in the feed movement backward, a cutting-shaped lifting edge 119 engages in the parting plane between the fold-up edge of the upper frame 61 "and the lower frame 57 '. To facilitate this intervention, it may be expedient to subject the frame to positive guidance over a curved surface before the lifting edge 119 is reached, in order to enlarge the dividing joint at the edge of the upper frame 61 "to be folded up or even to blow this edge out of its holder in the lower frame 57 ' When the frame is pushed all the way out of the magazine floor exit guide 120, it falls a short distance onto a resting floor 121 under the lower edge 56 of the magazine shaft side wall 54 or 115, the upper frame 61 "still being remains open by the lifting edge 119. 11, following the cutting process, the slide film piece 35 to be framed is entered into the film receptacle depression 58 in the subframe 57 'via an inclined transfer plane 40. There is then a feed arrangement corresponding to that of the lower magazine ramp slide 76 according to FIG. 7 or FIG. 8 in the second half cycle of the function of the frame closing mechanism, and the mounted slide frame is pushed back along the plane of the rest floor 121 by a frame closing device 64, which is again symbolically shown as a pressure roller arrangement 63 and in which the upper frame 61 "is folded onto the lower frame 57 ', anchored therein in a force-fitting or positive manner and then transported further to the delivery zone 62 for removal of the finished-framed slide 65.

The vertical section illustration according to FIGS. 12 and 13 through the framing zone 88 of the slide cutting and framing device according to the invention corresponds to the illustration in FIG. 6, but without a detailed illustration of an implementation example for the transfer plane 40 and for the cutting zone 20 above the case - And straightening shaft 53. A one-piece slide frame 157 with an upwardly directed film receiving depression 158 is arranged below the shaft side walls 54 with respect to the vertical axis of the shaft 53 and aligned transversely thereto. This is designed in the form of a window opening 230 which on one side of the frame 157, in the drawing on the top, is somewhat longer than the frame width of the slide film piece which is cut to size and ready for framing. In the transverse direction to this, the window opening 230 on this side of the frame 157 has a clear height parallel to the frame surface which is greater than the clear height on the opposite side of the frame 157, which is shown below in the drawing. Along the two longitudinal edges of the window opening 230, which run perpendicular to the plane of the drawing, extend approximately in the central longitudinal plane of the frame 157 and thus in the plane of the slide film piece later framed in this frame 157, groove slots 232 opening towards one another, the groove bases 233 of which are one Distance from each other, which is slightly larger than the height of the slide film piece 35 to be framed, which is the clear width between the perforation edges of a film strip from which the individual slide film pieces to be framed are cut out.

In front of the front slot 232 'and behind the rear slot 232 ", abutment surfaces 234 of abutments 235 rest on the frame surface 236. These abutment surfaces 234 go into convex, curved bending jaws 237 at a slight distance above that to the adjacent longitudinal window opening edges 231 Frame surface 236, which in turn run upwards into the inclined longitudinal side walls 54 of the shaft 53.

The rear abutment 235 ″ can be moved back and forth towards the front abutment 235 ′, sliding over the frame surface 236.

The slide film piece 35 to be inserted into the frame slots 232 and thereby to be framed is moved downward between the side walls 54 of the drop and straightening shaft 53 due to the action of gravity until it is centered on the window opening 230 above its larger opening area Groove slot walls 238 and thus rests on the frame surface 236. The rear abutment 235 "is then advanced until its bending jaw 237" projects beyond the rear longitudinal edge 239 "of the slide film piece 35 and the rear abutting surface 234" comes into contact with this longitudinal edge 239 ", and further, with the slide film piece being advanced 35 to the front abutment 235 'until the rear film piece longitudinal border 239 "falls in front of the forehead of the rear window opening longitudinal border 231", into the film receiving depression 1 58 and falls onto the lower, projecting slot wall 240 ", as shown in FIG. 12 b shown for a film piece 35 shown in solid lines.

When the rear abutment 235 "is advanced further, as shown in dashed lines in the illustration 12b of FIG. 12, the slide film piece 35 (due to the abutment of its front longitudinal edge 239 'against the front abutting surface 234') is bulged upwards in the middle region, supporting the area of the rear film piece longitudinal edge 239 "against the rear upper slot wall 238" and the rear bending jaw 237 "located immediately in front of and above it.

Together with further advancement of the rear abutment 235 ", as can be seen in particular from the illustration 12c, the slide frame 157 is advanced under the front abutment 235 'in the direction of an output zone 62 for the fully framed slide 65, cf. the illustration 12d. As the slide frame 157 advances along with the further advancement of the rear abutment 235 ", the front window opening longitudinal edge 231 'slides under the front abutment surface 234', whereby the front longitudinal edging 239 '- against the front abutment surface 234 'rests and a pressure component experiences downward from the front bending jaw 237' - is pressed down in front of the entrance opening of the front groove slot 232 'and by the slide film piece 35 relaxing in the plane under the front groove slot wall 238' is pushed in. The slide 65 framed in this way can then be pushed all the way under the front abutment 235 'and output, as shown in the illustrations 12c and 12d.

It is therefore important that the rear, displaceable abutment 235 "is advanced at least so far on the frame surface 236 that the rear film piece longitudinal edge 239" falls into the window opening 230 - and preferably onto the adjacent area during the Bulging phase of the slide film piece 35 from the rear bending jaw 237 "still maintains a pressure component in the direction of the window opening 230 - and then, due to the advance of the slide frame 157, the rear longitudinal edge 239" is first inserted into the rear slot 232 " and the front longitudinal edge 239 'is blasted into the front groove slot 232'. Contrary to the basic illustration 12b-12d, it is not absolutely necessary for the rear abutment 235 "to be advanced further with the slide film piece 35 which has already been gripped on one side , and it is also not necessary that the rear abutment 235 "up to the stop against d he front abutment 235 'is advanced and then stopped here, while the framed slide 65 is advanced further below and output through the output zone 62. For example, a driver could be arranged on the slide guide 241 in the region of the rear shaft side wall 54 ", which prevents further advancement of the rear abutment 235" by locking as soon as the front film piece corresponds to the representation 12b to 12c in the case of movement transition. Longitudinal border 239 'was blasted into the front groove slot 232', so that the downward pressure component of the rear bending jaw 237 "is no longer required. On the other hand, if a further advance of the rear abutment 235" is provided together with the framed slide 65, Within the scope of the present invention, comb-like toothing of the opposing bending jaws 237 and abutment surfaces 234 can ensure that the opposing front surfaces penetrate one another, by moving the rear abutment 235 "from the position shown under 12b against the illustration 12c and 12d same distance is advanced, such as the frame 157 to be output as a framed slide 65.

FIGS. 13 to 15 show a device-technical solution which does not make use of these possibilities, but which is based on the constructive solution according to FIG. 12 in the interest of the simplest possible mechanical and transmission-technical structure.

As can be seen from FIG. 12 and FIG. 13, in this preferred constructive embodiment, a frame feed device 242 is arranged under a slide frame magazine 166, which by means of a ramp slide 176 removes the lowest of the slide frames 157 from the magazine 166 and under the pushes the rear abutment 235 "through under the drop and straightening shaft 53. The nose-shaped ramp slide 176, which is in the rest or movement starting position behind the magazine 166, is arranged on a carriage 174 which is in or under the bottom 55 of the shaft 53 and the magazine 166 are guided longitudinally and are supported by a prestressed compression spring 243 against a longitudinally displaceable sliding block 244. This is U-shaped in cross-section, with side walls 245 running parallel to the direction of advance and protruding above the shaft bottom 55 (cf. FIG. 14) Between these is transverse to the direction of advance and between the rear shaft side wall 54 "and the front boundary of the slide frame magazine 166, a pivot axis 246 arranged, which the back current abutment 235 ". In front of the pivot axis 246, a pressure force acts on the rear abutment 235, which presses the rear abutment surface 234" firmly onto the slide frame surface 236, in order to contribute to a slide film piece (35 in FIG. 12) lying thereon of the abutment feed movement reliably and without wedging effects on the rear longitudinal edge 239 "for the feed into the film receiving depression 158. In the illustrated implementation example, this pressure is exerted by leaf springs 247 arranged on the surface of the protruding sliding block side walls 245.

In front of the rear abutment 235 ", the front abutment 235 'is arranged on the device base 55 at such a distance that the distance between the bending jaws 237 to be pointed towards one another in the initial movement position of the frame feed device 242 corresponds to the distance between the groove bases 233 of the groove slots 232 in the slide frame 157 and thus approximately corresponds to the height of the slide film piece 35 between its perforation longitudinal edges 239, the abutting surfaces 234 of both abutments 235 pressing onto the slide frame 157 outside the window opening 230. For this pressure of the front abutting surface 234 ' the front abutment 235 'is in the region of its bending jaw 237' under the impression of a compressive force caused, for example, by a helical spring 248, and the holder 249 for fastening this front abutment 235 'to the floor 55 allows a certain pivoting movement.

The horizontally acting pressure force components are predefined by appropriate dimensioning of the slideways and in particular also the preloaded compression spring 243, the leaf spring 247 and the coil spring 248 such that when the frame feed device 242 moves forward from the rest position, it is initially supported by the preloaded compression spring 243 the sliding block 244 is taken along, the rear abutment 235 "is thus pushed over the frame surface 236, but the pressure of the front abutment 235 'on the front area of the frame 157 is sufficient to first ensure that the rest position under the shaft 53 is maintained. The lowermost frame 157, which is pushed forward from the magazine 166 from the ramp 166 during this movement phase, initially maintains the original distance to the rear abutment 235 ", while the distance to the frame 157 to be fitted under the shaft 53 decreases. When the rear abutting surface 234 "passes over the rear frame longitudinal border 231" and thus the rear slide longitudinal border 239 "(see illustration 12b in FIG. 12) has lowered from the frame surface 236, the magazine 166 moves forward the bottom slide frame 157 pushed out abuts against the slide frame 157 to be fitted. The additional propulsion force thereby exerted on the latter causes the opposing friction component resulting from the action of the coil spring 248 to be overcome and this frame 157 to be fitted is pushed under the front abutment 235 'in order to burst the bulged slide film piece 135 with its front longitudinal edge 139' into the front groove slot 232 'as shown in FIG. 12b in FIG.

If the frame 157 thus equipped and with it the rear abutment 235 "is advanced so far from the inserted slide frame 157 that the rear abutment 235" comes into contact with the front abutment 235 '(illustration 12c in FIG. 12), that is also the sliding block 244 can no longer be moved forward, then, with further advancement of the slide 174, compression of the prestressed compression spring 243 begins in order to push the pushed-in frame 157 completely under the shaft 53 and thus at the same time the framed slide 65 out of the exit zone 62 ( see illustration 12d in FIG. 12).

In the subsequent return movement of the carriage 174, the compression spring 243 first relaxes again to its pretensioned state, in order to then pull the sliding block 244 and thus the rear abutment 235 "back into the starting position, while the beveled rear flank of the ramp slide 176 the frame which is now to be underlaid 157 lifts in order to be able to return to the starting position shown in FIG. 13.

As can be seen from the illustration in FIG. 14, in the interest of a tilt-free movement sequence on the sliding block 244, guide pins 251 extending transversely to the device base 55 are arranged, which engage in guide slots 250 in the device 55 which are fixed to the device. Instead, guide rods can also be arranged on the sliding block 244, which are guided parallel to the floor 55 in a device-fixed manner.

As can be seen from FIG. 15 in connection with FIG. 13, the slide 174 is not only guided longitudinally by the ramp slides 176 penetrating the bottom 55, but in particular parallel to the longitudinal extension of the prestressed compression springs 243 in a slide track incorporated in the slide block 244 252 for a slide-fixed guide plate 253.

For the advancing and retracting movement of the slide 174, a rocker arm crank mechanism 254 is provided with a crank disk 68 aligned parallel to the floor 55, similar to the solution according to FIG. 8. Regarding the drive of this crank disk 68 and purpose Moderate measures for coordinating the operating operations of the slide cutting and framing device according to the invention are referred to in full in terms of content of the corresponding explanations, in particular with regard to FIG. 8. The rocker arm 255, which is designed as a cranked, one-armed lever, is operatively connected to the crank disk 68 via a slideway 173 which is incorporated in it and into which a sliding block 172 engages. One rotation of the crank disk 68 causes the rocking lever 255 and thus the slide 174 to move back and forth, that is to say the longitudinal insertion of the film piece 239 into or into the groove slots 232 with the output of the framed slide 65 upon presentation of a further slide to be fitted -Frame 157 under the drop and straightening shaft 53. The corresponding feed and retraction movements of the slide 174 and the abutment slide block 244 as a result of a pivoting movement of the rocking lever 255 engaging on the slide 174 are indicated in FIG. 15 as double arrows.

It is appropriate to utilize the movement of the drop and straightening shaft 53 described in connection with FIG. 10 for the slide film piece 35 cut to size, ready for framing, after the upper frame 61 'has been fed in for its at least provisional fixation on the lower frame 57 by fixing the film piece 35 . For this purpose, the shaft 53 is preferably folded out before the upper frame 61 ′ is inserted against a restoring spring force, which is released around the shaft 53 in the course of the further movement of the cross-loop slide 74 (see, for example, FIG. 7) to snap his rest position back. In doing so, he strikes the upper frame 61 ', which experiences a first positive connection with the lower frame 57 via the tongue and groove arrangement designed for this by the impact. The final connection is then made by a frame locking device with pressure claw 79 (FIG. 7) or in the course of presenting a new subframe 57 when it is pushed out through a pressure roller locking device 64, as indicated in FIG. 11.

For the impact of the recoiling shaft 53, it is more favorable and, with regard to straight-line movements oriented only at right angles to one another, it is more advantageous to provide the realization according to FIG. 16 in this regard. Here, the drop and straightening shaft 53 for a cut piece of film 35 is arranged coaxially in a frame shaft 116, which serves to guide the fall of upper frames 61 ', which have at least approximately the same external dimensions as the lower frames 57. After the film piece 35 has been transferred from the transfer zone 36 into the subframe 57 (illustration 16a in FIG. 16), the film piece guide shaft 53 is raised up to an input opening 301 on the bottom of the slide frame upper magazine 60, which is approximately in the plane of the transfer end 52 for the film piece 35. In the course of the movement of the cross-loop carriage 74, the upper magazine ramp slide 77 is then advanced in order to advance an upper frame 61 'into the frame shaft 116 (illustration 16b in FIG. 16). A spring-loaded support claw 302 in the immediate vicinity of the input opening 301 prevents the freely projecting upper frame 61 'from tipping over too early. The upper frame 61 'then falls onto the lower frame 57 equipped with the film piece 35. The alignment takes place via the frame-shaft side walls 115 adjacent to the magazines 60, 66 and the side wall opposite the transfer zone 36 (in the sectional view of FIG. 16 and predominantly and therefore not visible) as well as the leaf springs 303 arranged opposite to press the lower frame 57 and upper frame 61 'against the side wall 115 opposite the transfer zone 36.

As shown in detail in FIG. 17, the pretensioning lock of the raised shaft 53 in the advanced position of the upper magazine ramp slide 77 (illustration 16c in FIG. 16) is now released, and the shaft 53 swings downward around the upper frame 61 'to be connected to the lower frame 57 by impact.

The further movement of the cross-loop crank drive 67 (cf. FIG. 17) now causes a reversal of the movement of the slide 74 and thus a pushing of the lower magazine ramp slide 76 to present a new lower frame 57 in the frame shaft 116 under the slide shaft 53 while pushing it out of the completed slide frame into an adjacent frame closing pressure roller arrangement 63. Here, between the rollers covered with circumferential rubber beads, the upper frame 61 'and the lower frame 57 with the slide film piece 35 in between and their output as a framed slide 65 take place either when the next one is fed framed slides 65, or manually through a handle opening 304 (illustration 16d in FIG. 16).

With regard to the coupled, oppositely acting lower magazine and upper magazine ramp slides 76, 77 on the slide 74 of a cross-loop crank mechanism 67 for carrying out the framing process described in connection with FIG. 16, the exemplary embodiment according to FIG. 17 functionally corresponds to that according to FIG. 7. However, the overall structure is now simplified in that the pressure claw locking device 64 '(FIG. 7) because of the locking function assigned to the movable shaft 53 - especially in connection with the Frame closing pressure roller arrangement 63 (see FIG. 16) can be omitted.

A ramp-shaped cam lever 305 is articulated on the slide 74 in order to raise the film drop and straightening shaft 53. When the carriage 74 moves in the direction of advance of the upper magazine ramp slide 77, the beveled run-on end 306 of the cam lever 305 moves under a trunnion 307 which is fastened to a lever arm 308. As a result of folding up the lever arm 308 against the force of a return spring 309, the shaft 53 is raised in an axially parallel straight guide 310 on the frame shaft 116. The geometry of the cam lever 305 is selected in such a way that the shaft 53 is raised above the input opening 301 (see illustration 16b in FIG. 16) before the upper frame 61 'which is simultaneously pushed into the frame shaft 116 under the film Shaft 53 protrudes.

For tilt-free, ie functionally reliable lifting of the shaft 53, the lever arm 308 acts via a support curve 311 on a film shaft-fixed cantilever arm 312 which is dimensioned such that a lifting force which is oriented exactly parallel to the straight guide 310 is effective in each inclination of the lever arm 308.

In a feed position of the upper magazine ramp slide 77, in which (illustration 16c in FIG. 16) the advanced upper frame 61 'has already fallen down in the frame shaft 116, shortly before the reversal point of the movement of the slide 74, the cam lever 305 pulled out with its rear end 313 under the lifting pin 307, so that the return spring 309 suddenly pulls the lever arm 308 and thus the shaft 53 back into the lower rest position.

When the carriage 74 moves back to advance the lower magazine ramp slide 76, the cam lever 305 moves above the lifting pin 307 into the starting position shown in FIG. 17, specifically in the interest of the smallest possible height of the device close above this. So that the lifting pin 307 finally comes to rest in front of the run-up end 306 of the cam lever 305, at the end of this return movement, the cam lever 305 is folded up about a swivel joint 314 against the restoring force of a spring 315.

Also in the interest of the low overall height of the device, which is desirable for working with the device when the operator is sitting in front of a table, in order to be able to view the film strip inlet viewing zone 4 and the cutting zone 20 from above, the cutting zone 20 is, for example, contrary to the illustration in 5 expediently equipped with upper knives 24 'in the form of two-armed levers, as shown in FIG. 18.

The elastic adjustment of the upper knives 24 'relative to the stationary counter knives 28 now takes place via an expansion tension spring 316 between the shorter lever arms 317 which do not act as knives. In the region of their pivot axis 27, the knives 24' are connected in a rotationally rigid manner to a shaft 318 which is mounted fixed to the housing , which has an angled end 319. In order to carry out the cutting process, this end 319 can be pressed down against the force of a return spring 34 'by means of a key handle 26' in a slot guide 32 'fixed to the device.

The design and actuation of the knives 24 'according to FIG. 18 in comparison to that according to FIG. 5 has, in addition to the advantage of a lower overall height, in particular also the advantage of moving the handle 26' out of the area of the cutting zones 20 in the middle of the device To be able to move the housing side wall 320, which is opposite the rotary handle 69 for the cross-loop crank mechanism 67 (cf. FIG. 1 in connection with FIG. 17), that is to say in the vicinity of the handwheel 12 (cf. FIG. 1) for the advancement of the filmstrip 3 through the viewing zone 4. In this way, two-handed work with undisturbed viewing of the filmstrip 3 is possible with the device according to the invention, by first actuating the handwheel 12 and then the cutting handle 26 'with the left hand and then the framing process is connected with the right hand via the drive of the rotary handle 69.
