¹¹ Machine for cutting developed film strips into film sections and for framing them in slide frames. "

The invention relates to a machine for cutting up the developed film strip in film sections and framing the same in slide frames one or both halves of the frame can also be provided with cover glasses

A framing machine is known which consists of a single-piece snap frame spread out in one plane Cardboard or plastic are fed in after the film section has been placed on one half of the frame the frame is closed by folding the other half of the frame and hot-seal gluing on cardboard or mechanical locking performed on plastic The film section is placed on the lower half of the frame as long as the frame is nooh in paused in the half-open position in the reticle, through a through the picture window opening of the lower frame half through-reaching suction element, which is located at some height above the frame Film section captured nooh before cutting. Then the suction element, which goes back downwards, leads

- 2 the film section in the frame level and holds it there until the frame is finally closed. The main disadvantage is that the folding frames must be packed and fed in the stretched position. The packaging volume must therefore accordingly Be kept larger than necessary · Also requires the closure of a hinged frame a complex machine design from the extended position, because more processes have to be carried out

In another known machine for the use of two-part frames, the insertion takes place of the film and see fixation in the same or a similar way ο Bs is only the one to be addressed as a cover second frame part at a subsequent job over the film section with inserted provided frame main part and only then from above on this for implementation applied to the latching. The two frame halves have to be packed in different stacks to be delivered. The protruding locking projections require an even larger packaging volume than is the case with snap frames «In addition two magazines must be provided on the framing machine and separated with the two frame parts be filled. Here, too, complex machine design is required

In another framing machine, in which the main frame part has one of under-grip edges has surrounding lid receiving space, in which the smaller deodorants with wedge-shaped edges is crushed in a position temporarily bent by elastic material bending already a gripping member for the film section has been designed as resilient pliers, the such

_Λ works that by cutting a son's oath

Direction cut film part in the with the receiving space for the cover part lying upwards Frame lower part is introduced. In this position he is then held by suction air, whereupon only the cover is attached and snapped in here is the separate feed of the two frame parts, a suction air generation and a mechanically complex device for the temporary

Reshaping of the cover to be pressed in required. Ί

Finally, a taming machine is known in which the Rähmchan already have their standard of use when they are introduced into the machine , and only then; in this by Lpoher of the frame main part hindui aleitte pins are opened, which temporarily transfer the cover lying behind it in a widened position of the frame main part. This machine has the disadvantage that the film is cut before it is cut

the Filmabschnittea duroh a knife only partially inserted in the partially open frame wirdc After cutting the film portion that is in the image area, the image window openings duroh of both frame parts (main body and cover) \ through gripped by pincer-like gripping members, and in the final position within the frame drawn into it. There is a risk that the pincer-like gripping of the film image in the image area will cause damage or contamination of the same. The introduction of the film that has not yet been cut into the opening area of the frame has the disadvantage that those parts of the film tape that should not or must not be framed as a result of incorrect exposure or for other reasons require cumbersome manipulation in order to remove such an unusable piece of film from the framing process outsource if the expensive process is not to be used to frame such committee posts and thereby uselessly use up slide frames.

Incidentally, another all treatment-adherent Rahmungsmaschinen disadvantage can be seen in the fact that o with picture window openings covering cover glasses. Like. Equipped frames are not \ usable · \

In contrast, the invention is based on the object to create a framing machine for slides with or without cover glasses, whereby the frame already in compliance with the smallest storage volume in their form of use and delivered be introduced into a magazine of the machine in front of the first processing point in which only one temporary lateral, but ample :( 'measured opening through sohrag position of the lid «

part is formed, the film sections always have the maximum length in accordance with the regulations and not in the area of mechanical pressing filing are recorded with the ultimate goal of designing the training so that the prerequisites for a fully automatic mode of operation can be created.

The invention solves this problem in that the

l ~ sonic device two parallel to each other ver

running, in their distance of the maximum length of the film section corresponding cutting elements, preferably Has Hebülscheren, and in the space between these a film section grasping at the edge, e.g., pincer-like gripping device which grips the severed film section into the open frame up to the end position, in which the reopened and returning gripper the film section

releases, the duroh now in the closed position returning cover part is pressed against the lower part of the frame.

Such a design of the machine corresponds to the conditions of the Erax_s; because in order to rationalize the development of mimes it has become customary in development institutes for films in which the frames are also framed to glue a large number of films with their ends butt against each other and to roll them up, so that special care is taken in the trimming in the areas required at the beginning and end of the film. The films are also exposed in a wide variety of recording devices, so that the distances between the individual images are different and the trimming must often be regulated by hand or by optical control devices. On the other hand, the length of the image sections may be _; Do not exceed a certain maximum dimension with regard to the recess provided for the recording on the inner frame wall, because otherwise the locking means on the frame would not come into the correct position and therefore the complete closure of the frame would be prevented by the overlong film section.

With one movement of the son's tool, two cuts can be made through the distance between the two soheres in the height of the length of the film. The advantage of this is that »that ^! the film-section shortly before the end of the cut in the cocked position τ on the intermediate in] space between the two lever pairs of blades arranged pincer-like gripping device so siehe-

-v rer recorded and in the intended bundling

is introduced in the framework.

In a preferred embodiment, on the side of the frame guide facing away from the gripping device, above the frame, a preferably bar-shaped pressure member movable downwards like this arranged that it presses the edge of the lid against the frame base and the just inserted Film section additionally tensed at this point.

In a further implementation of the invention, one which feeds the film strip is advantageously C-shaped profiled guideway parallel to the frame | Guideway arranged; · This creates a particularly favorable arrangement of the trimming and Gripping device allows and you width of the Machine reduced and the clarity of the transport of frame and film improved.

In order to influence the ready-to-use frame entered into the single hopper so that their cover for a certain time on the edge facing the film guide into a temporary one

The opening position is raised / is at that of the film guide track facing wall of the frame guide track at a first job behind the filling chute an upwardly directed resilient pawl is arranged, which is guided by the perforations the frame main part penetrating pins raised cover part of the frame on his Engaging behind the opening edge in an intermediate position

At a second work station on the same wall of the frame guide track, a support strip for the front free edge of the cover is arranged which, in order to expand the frame opening in the next step of the frame at the height of the previous pawl, has a sloping track which then rises at this new height passes ahn a plane ^B. So the opening stroke of the lid is brought about in two stages in order not to overstrain the lid material »

The cutting device located at a third job has the opened

The slide frame (Fig. 1) consists of a frame base part 1 with a hollow space, shown in dashed lines, surrounded by a circumferential edge for receiving the cover part 1 ^a . The frame base part 1 has in its corner areas curved Druohbrbruch 1 for the reception of correspondingly shaped projections 1 ° of the cover 1 ^a , which obstruct verrasuend.

Fold down a frame opening at the upper end when the upper two projections 1 ^{C are} temporarily pushed out of the openings 1, while the opposite two Yerrastungen are prevented from unlocking by appropriate tensioning. In the case of framing without glass, the frame only consists of these two parts. When using cover glasses, the frame is the main part

Mistake.

In the other frame (Fig. 2), the base part and the cover have the same design as before. However, here openings 1 are only provided at two corners and the cover 1 ^a accordingly has only two latching projections 1 °. At the opposite edge of the cover part 1 ^{a is} via a channel 1 ^{d acting as a joint}

sits in the corners each einn Durchbruoh 1 ^e for receiving a riveting projection 1 of ^{the cover part 1 a} , so that the cover around the joint 1 to

Formation of a ^ frame opening can be temporarily folded down.

In the third frame (Pig. 3) the frame main part 1 again has the same design as before, only the cover part 1 ^{a is} in two corner areas

ohen 1 attached by hinge pins, not shown. The main frame part 1 has a recess 1 on the opposite edge into which sioh

k an overlapping edge projection 1 inserts latching. By acting on this projection 1, the cover part 1 ^a can therefore be partially opened temporarily for the purpose of inserting the film section These 3 types of rähmohen allow a delivery in ready-to-use condition in the framing smaeehine ·

The filling chute 2 accommodates the frames 1 located in the brewery farm. From it, the lowest frame 1, 1 ^a is pushed into the frame guide loist 5, which has a C-shaped cross-section, first into the working position I and then gradually moved through the other working positions II, III, IV into a working position V, by means of a slider 3 which the finished frames are pushed through a slider 6 into the waiting, not shown, packaging box.

If the frame 1 is at work site I in the O-shaped guide 5 (FIG. 7), one edge area of the frame 1, 1 ^{a is} kept closed, while a slide 7 with pins 7 ^a through the openings 1 of the main frame part

In this way, after a time which has a favorable effect on the material for bringing about the overall opening, the free edge of the cover 1 ^{a is transferred} to a support strip 9, which initially has an upwardly sloping path 9 ^a , to which a flat, higher path 9 is attached adjoins, on which the cover 1 ^a also remains at the work site III until the film section 10 has been formed there and inserted ^{into the open frame 1, 1 a.}

The film 10, which (Fig. 5) partly as a normal film with rows of holes 10 ^a , z, T. is shown as a Pak film with only one hole 10 ^a per image on only one edge, runs in a film guide 11 arranged parallel to the frame guide 5 here with an approximately C-shaped cross-section and thereby reaches the height of the work station III of the frame guide 5 «an this point is a cutting device, which is designed here as a double lever scissors

It may be opened in order not to prevent the frame from closing correctly later. In the space between the two pairs of Soheren knives 12, 12 there is a pincer-like gripping device 13 "13" consisting of two legs, which here can be pivoted around a bearing 16 with an arm 15 Bolt 17 downwardly pivotable tong legs 13 pulled by the pull rod 14 against the lower tong arm 13 and locked in the gripping position by a latch 18 falling behind it until the process of inserting the film absehnitbes into the frame is completed (see the extended position of the gripping device with the dashed representation of the same in the starting position.) Shortly before the end of the forward movement, the latching pawl 18 is held up, for example by the cutting device 12, so that the relieved pincer hooks 13 release the miming section 10 introduced ^{into the frame 1, 1 a.} The gripping tongs 13, 13 grips the film section 10 separated at the same time only at the free, un-

When the running movement becomes effective, a resilient pressure bar like 19 could be arranged at the previous work station III. The width of these pressure organs 19 or 24 can be limited to such an extent in relation to the hand of the frame with a correspondingly resilient design that in the presence of cover glasses on one or both frame halves 1, 1 ^a there is no danger for them.

In the case of normally perforated films, Pak films and unperforated films, you can also capture, cut off and frame the last image section and the subsequent part that bears the customer code, without the need for special mechanical devices, if appropriate observation and control done by hand or with electronic control means. In Pak films with only one punch 10 ^a per image, the last usable image section and the marking end section do not have a hole for the engagement of the transport means for the film Film guide 11 is provided with a punching device 25 which can be operated by hand or, in the case of fully automatic actuation, by control means.
