Aug- 2, 1%@ F. G. Kam-1L METHOD OF MAKING A PICTURE SLIDE Filed Jan. 28, 1965 United States Patent Office Patented August 2, 1966 3,264,154 METHGD F MAKING A PICTURE SLIDE Paul G. Kielli, St. Louis, Mo., assigner to Church-Craft, Inc., St. Louis, Mo., a corporation of Missouri Fiied Jan. 28, 1963, Ser. No. 254,101 2 Claims. (Cl. 156-108) The present invention reiates to picture slides and to a method of making the same.
Many approaches have been made to the production of a satisfactory slide adapted to be viewed by a hand viewer or projected onto a screen, or the like, and of a simple method of making the slide. But even with the developments to date, there has remained the long standing need of a simple, accurately made slide land a simple method of making the slide, particularly in and for low cost mass production.
Therefore, an object of the present invention is to provide a slide and method of making the same which supply said long existing need.
In brief, a preferred embodiment of the present slide comprises two contiguous windowed pieces of suitable material, each having pressure sensitive adhesive on the adjacent sides. Mounted in the window, or in each Window, is a segment of photographic lm, secured rmly between the pieces by the pressure-sensitive adhesive.
The present novel method of making the slide contemplates appropriate steps of providing the windowed pieces of material with adhesive thereon, mounting the film segment or segments in place on one piece, and bringing the pieces into adjacent relationship.
Hence, another object of the present invention is to provide a novel picture slide in which the iilm is firmly, permanently and accurately anchored.
Another object is to provide a novel picture slide of superior quality which is economically mass produced.
Another object is to provide a novel mass production method of making a permanent picture slide which is efficient yand effective.
The foregoing and other objects and advantages are apparent from the following description taken with the accompanying drawing, in which:
FIGURE 1 is a plan view of a diagrammatic layout for effecting the present novel method of forming a picture slide;
FIGURE 2 is a side elevational view of the diagrammatic layout of FIGURE l;
FIGURE 3 is a view of the pressure sensitive adhesivecovered back sides of two joined windowed pieces;
FIGURE 4 is a view similar to FIGURE 3 with picture lm segments positioned over selected windows;
FIGURE 5 is a plan view of a completed slide; and
FIGURE 6 is an enlarged transverse cross-sectional view taken on substantially the line 6-6 of FIGURE 5.
Referring to the drawing more particularly by reference numerals, 10 indicates generally =a picture slide of the multiple stereo type incorporating the teachings of the present invention. The slide 10 comprises aligned adjacent pieces 12 of paperboard, or other suitable material, the adjacent surfaces of which are covered with pressure-sensitive adhesive 14. As illustrated, each piece 12 has four windows 16, but each may have one, two or more than four windows 16, depending upon the type of slide 10. A picture film segment 18 is trapped between the pieces 12 for each aligned pair of windows 16. The pressure sensitive adhesive 14 firmly and permanently holds the pieces 12 together and the film segments 18 in place to provide a superior slide 10.
The present novel method of making the slide 10 is illustrated diagrammatically in FIGURES l and 2. A roll 20 of continuous paperboard 22 having pressuresensitive adhesive 14 on one side masked by a continuous removable strip or backing 26 is provided. The continuous paperboard 22 is printed with a desired repeating legend or pattern on the side opposite to the pressuresensitive adhesive 24 and is cut to provide windows 16 before being formed into the roll 20. The paperboard 22 is also pre-slit centrally longitudinally, except for spaced bridging tabs.
The roll 20 is supported for unrolling, and the continuous paperboard 22 and strip 26 are drawn across a knife 28 disposed transversely thereto. The knife 28 cuts the continuous paperboard 22 into the pieces 12, but does not penetrate the backing strip 26, which is peeled back from the pieces 12 onto a roll 3ft just before the pieces 12 pass through a mechanism 32 which receives and segments continuous picture film 34 and applies the segments 18 to selected windows 16, the segments 18 being a little larger than the windows 16 and being secured in place by the pressure-sensitive adhesive 14. After leaving the mechanism 32, the lightly attached pieces 12 are folded into adjacent relationship by a suitable device 38, the engaging pressure-sensitive adhesive 14 holding the pieces 12 firmly together and the film segments 18 securely and permanently trapped.
At the present time nearly a hundred slides per minute can be completed by the foregoing method from printed windowed continuous paperboard 22. The method provides an economical efficient way of producing slides 10, repetitious individually or in series.
It will be readily appreciated that the invention includes standard stereo slides, single window slides, and the like, which can be made by the novel method. The pressure sensitive adhesive 14 `can be applied other than over the entire adjacent surfaces; for example, it may be applied to one surface over-all or selectively striped, depending on the slide being formed. Other applications are apparent.
It is manifest that there have been provided a novel picture slide and a novel method of producing the same in lots.
It is to be understood that the `foregoing description and the accompanying drawings have been given by way of illustration and example. It is also to be understood that changes in form of the several parts, substitution of equivalent elements or steps, and rearrangement of parts or steps, which will be readily apparent to one skilled in the art, are contemplated as within the scope of the present invention, which is limited only by the claims which follow.
What is claimed is:
1. The method of making a picture slide comprising the steps of providing pre-printed pre-windowed material having pressure-sensitive adhesive on one side protected by a mask, the material being scored along a central line to provide a fold line and to divide the material into complementary halves, feeding the masked material towards a film segment applying area, cutting the material into pieces of predetermined size while the material is protected by the mask and prior to reaching said film segment applying area, stripping the mask from the pieces prior to passage thereof into the film segment applying area, depositing a predetermined number of lm segments on the pressure-sensitive adhesive of one of the halves of the material for viewing through the windows, and `folding each piece along the score line into slide form with film segments trapped between the two halves.
2. The method of mass producing picture slides comprising the steps of supplying a roll of pre-windowed material having masked pressure-sensitive adhesive selectively located on at least one side, reducing the material to pieces of the proper size for slides prior to unmasking the pieces, unmasking the sized pieces, applying lm segments to Windows with overiying portions of the lm segments extending beyond the windows and making com tact with adhesive adjacent the Windows, and trapping the lm segments between adjacent pieces.
