PROCESS CHARACTERIZED IN THAT THE UPPER AND LOWER FRAMES OR HALF-FRAMES ARE FOLDED IN ACCORDANCE 7 AND CONDUCTED IN THE FORM OF A COHERENT ASSEMBLY WITH JUNCTION BARS 4, TO A SEPARATION DEVICE AND FEED AS INDIVIDUAL PARTS IN THE FRAMING DEVICE OF SLIDES 9. METHOD APPLICABLE TO A SLIDE FRAMING MACHINE.

Description

  The present invention relates to a method for feeding frames and half-frames of slides to a

  device for producing the slide frame.

  The invention extends to blanks for a frame for

  can be used for said process. It is known to feed slide frame halves for framing slides, from "wells" or stacking channels for upper and lower halves of frames. In this operation, a slide to be framed is cut in a film strip and deposited in a half-frame fed from a special stacking well, to which it is fixed by means of a point of glue. Then a half-frame, brought from another stacking well, is placed on the first half-frame and pressed on it to complete the operation

of supervision.

  The placement of frame halves in the stacking wells takes place in the form of stacks of elements

  which can be either stamped in a

  synthetic material, stacked in advance on

  transport rods. After exhausting the battery

  viewed, it is necessary to place a new stack of half-frames in the corresponding stacking well of the

  machine to frame the slides.

  Modern slide frame machines have high working speeds. Due to the relatively frequent filling required of the stacking wells, however, they have the disadvantage of still very long downtimes, which are of the same order

  of magnitude than the actual working times of the machine.

  It is an object of the present invention to provide a solution which avoids these drawbacks of the present state of the art, by means of which the slide frame halves can be continuously fed to a framing machine, so that dead times produced by the introduction of a new battery in the supply wells are largely reduced or eliminated. For this purpose, the subject of the invention is a process

  characterized in that the frames or frame halves are

  folded accordion and are brought in the form of a set

  consistent with the framing machine, the frames or conjugate frame halves then being separated from the accordion and fed as individual pieces into the machine for

  the frame of each slide.

  Since the frames or half-frames

  The machines are first brought to the machine by being connected to each other in the form of an accordion, brought to the machine.

  is no longer produced in the form of piles of indi-

  viduals, but in the form of a chain (theoretically) endless, which allows a continuous supply so that downtime is spared. In addition to

  the saving of personnel made possible by this automati-

  In addition, the method of the invention has the advantage of a considerably lower risk of walking accidents than known installations in which each half of the lower frame must be removed.

  in a pile and brought to the installation of framing.

  According to the invention, it is possible to bring to the machine, on the one hand, the upper frame elements, and on the other hand, the lower frame elements linked between

  each one in layers folded in accordion. Another possibility

  lity is to bring to the machine the upper half-frames

  and the lower half-frames in each case a common layer of folding accordion. After joint separation of the accordion, and after insertion of the slide between them, the lower element and the upper element are

  folded against each other and linked together.

  According to another characteristic of the invention, it is possible to bring to the machine several upper half-frames and several lower half-frames each time.

  in a common layer of the accordion.

  The "frame blanks" for slides to be brought to the frame machine, interconnected by accordion folding lines, can be constituted such that these blanks are made, assembled together, by an injection molding process , the fold lines being formed in the form known as "film hinges". It can also be expected that the frames, as well as the "blanks" of frames are made especially being interconnected to the

  layers by means of elastic connection

ticks.

  The invention is equally suitable for diary executives

  positive in synthetic material than in cardboard frames.

  A particular advantage of the invention lies in the fact that the frames or half-frames, because of their folding accordion, are brought to the machine in the perfectly flat state, which is very important both for the introduction slide for later use of the framed slide.

  The invention is explained hereinafter with the aid of examples

  Embodiments with reference to the accompanying drawings, in which: Fig. 1 is a plan view of slide frame members interconnected by accordion folding, in which case upper half-frames and lower half-frames;

  juxtaposed, each time forming a layer of

  deon with five half-senior and five lower half-ranks; FIG. 2 is a plan view of a portion of FIG. 1 for another embodiment of the folding locations, and FIG. 3 is a schematic side elevation view of the delivery of the frames or half-frames, folded in accordion. , on a reduced scale with respect to FIGS. 1 and 2, to a separating device assigned to an installation of

frame separation.

  In accordance with Figure 1, each time one half

  upper frame 1 and a lower half-frame 2 are interconnected to be folded around the line indicated in

dotted 3.

  Several senior half-managers 1 and half-frames

  2 are interconnected by bars 4.

  In the example shown, it is each time five upper half-frames and five lower half-frames which together form an accordion folding layer of length A. The junction with another accordion folding layer takes place by means of a 5-fold fold line

  in appendices 6 of the sheet of material.

  The folding locations 5 are constituted in the embodiment of FIG. 1 as film hinges. As shown in FIG. 3, the accordion 7 made of several folded layers on one another can be brought to a separation device 8 of a

  Slide Installation 9 (not shown)

  detail). This supply takes place continuously, the accordion 7 may contain a chosen number at will frames or half-frames.

  As shown in Figure 2, it is also possible to

  according to the invention, to link together the

  individual layers of the accordion folding through the

  of special connecting pieces 10 in the form of articu-

  lation. By means of such connecting pieces 10, it is possible to connect a first accordion stack 7 to another similar stack, so that the framing machine can operate continuously without changing.

  interruption of an accordion 7 to another.
