Definitions

  • This invention relates to improvements in cards adapted for mounting projectable transparencies such as for example film record cards in which individual microfilm sections are mounted to facilitate the handling, filing and storage of the transparencies, and also the sorting out, projecting and if desired the reproducing of individual transparencies when desired.
  • the invention relates especially to novel blank cards adapted for such uses and to their manufacture.
  • the invention is particularly useful in mounting microfilm sections in cards that are capable of being sorted mechanically, although it is not limited to this use as explained hereinafter.
  • Various types of mechanical sorting systems are well known. They range from systems in which groups of related cards can be separated and extracted from a stack by inserting a pin or like instru ment through aligned holes in the edges of the cards, to the elaborate and well known IBM system in which the cards are perforated according to a code and are sorted by electrically controlled apparatus responsive to the location of the perforations in the individual cards.
  • the invention also comprehends the mounting of projectionable transparencies, including all types of photographic film records, in ordinary file cards, catalog cards, and the like.
  • the present invention comprises important improvements of the punch cards or aperture cards disclosed in the priod Langan Patents Nos. 2,511,859, 2,512,106, and 2,587,022, as well as in the preparation and use of such cards.
  • Aperture cards of the type shown in these prior patents have been very widely used, especially by the United States Government.
  • a current program of standardization of the preparation and distribution of engineering data by this system, such as drawings, specifications and the like, in one particular Government field is estimated to require 90 million aperture cards initially and average annual usage thereafter of million aperture cards.
  • any increase in thickness of such cards is very undesirable. Even though an applied strip of adhesive may only increase the thickness of a card by an extremely small amount, say ,1 of an inch, still when a deck of 1000 or more cards are stacked in a file drawer as is often the case, there will be a difference of an inch or more in the length of one side of the stack as compared with the other.
  • the prior Langan Patent No. 2,587,022 suggests heat bonding of thermoplastic materials to the card, proposing to cover the aperture with a sheet of cellulose acetate and to bond its edges by heat and pressure to the edges of the card around the aperture.
  • the material of this cover sheet was proposed to be the same as or similar to that of the base of the film itself, with the thought that subsequently the film section and the cover sheet could be united integrally by heat and pressure to form a unitary transparency across the aperture.
  • heat damage to the film resulted, however, such as clouding and/ or buckling or Warping of the film.
  • thermoplastic material and the thermoplastic film base as well are softened by heat so as to become tacky and merge or weld together under pressure to join the film to the card with a bond strength that is much higher than can be obtained by mere surface adhesion. It has been found, however, that the heat required to secure effective Welding and that warping or other damage to the card usually results.
  • the present invention involves to some extent an impregnation of the card fibers with bonding, material according to the aforesaid prior application Serial No. 70,814.
  • the bonding material should be one that is dry and non-sticky or non-tacky at ordinary temperatures and up to say 200 F., since business machine mechanisms often develop temperatures around 150 F. or more as the result of sustained operation.
  • the bonding material should be heat activatable at a temperature in the range of 250 F. to 350 F. Usuall it.
  • elastomeric and resinous products in suitable solvents such as methyl ethyl ketone, isobutyl ketone, acetone, and the like or in the form of fast drying emulsions.
  • suitable solvents such as methyl ethyl ketone, isobutyl ketone, acetone, and the like or in the form of fast drying emulsions.
  • the commercially available normally liquid adhesive known as Pliobond gives very satisfactory results. In fact, this material can be activated without heat by the addition of a small amount of solvent.
  • the zone of application of the solution to the card must be such that the bonding material will be located around the edges of the aperture, when it is eventually cut out.
  • this can be accomplished by applying the solution over the entire area of the aperture, or for that matter over the entire area of the card when it is manufactured, but it is more economical to apply the solution in a strip pattern following the outline of the aperture to be cut out, or of the several apertures to be cut out, as the case may be.
  • the solution can be applied in the desired strip pattern or patterns by hand by simply brushing it on the surface of the card, but usually suitable mechanical applicator means will be preferred.
  • the cards may be moved in succession through a zone in which the desired strip pattern application is effected by relative movement between the individual cards and suitable applicators.
  • a reciprocable stamping device with a suitable inker can be used, or the cards may be fed in succession through rotary printing devices; in either case the solution, colored or not, provides the ink with which the card is printed in the desired pattern.
  • cards embodying the present invention before the film is mounted therein, provide the very substantial advantages over the prior art mentioned above with regard to storage, distribution, etc.
  • the present invention provides further advantages of major importance because it is not necessary to heat-soften the edges of the film section and then to compress them together with the card to thin the edges by plastic flow and to force the film down into the aperture, as disclosed for example in prior Langan Patent No. 2,633,655 mentioned above.
  • the first step in the present invention is to indent one side of the card around the outline of the aperture eventually to be cut therein, so as to form a trench-like de pression in one face of the card and a corresponding ridgelike projection embossed on the opposite surface of the card. It will be apparent that this stamping or embossing operation can be performed by any suitable type of reciprocating or rotating die mechanism. While it has been proposed heretofore to pre-dimple such cards by compressing the edges of the aperture, as for example in the prior Patent No.
  • grooving or indentation of the card on one side can easily be made much deeper by permitting the card to be embossed on the other side, the stamping or embossing operation producing a sort of bending or folding of the card material instead of compression thereof.
  • the next step according to the present invention is to remove the ridge-like embossed projection from the opposite surface of the card in any suitable manner so as to restore the surface on this side of the card to a planar condition.
  • This can be accomplished by any suitable cutting or shaving operation, but most conveniently by high speed grinding or abrasion applied to the cards while moving relatively past the grinding device.
  • This produces a card which is substantially planar over one side, and is planar on the other side as well except that around the outline of the aperture eventually to be cut out, there is a trench-like depression the bottom of which is formed by a thin web of card material.
  • the combined thickness of the film-and of the ledge around the aperture (which ledge previously formed the bottom of the groove) is not materially, if any, more than the thickness of the card.
  • a card initially 0.0067 inch thick may be embossed and ground to a web thickness of about 0.015- 0.002 inch in the bottom of the trench around the aperture and the added thickness of the usual silver halide film of say 0.0055 inch makes a total of around 0.007 inch.
  • the depth to which the blank cards are stamped or embossed, and the corresponding thickness of the card material at the bottom of the groove may vary depending upon the kind of film to be mounted, the web being for example from about 0.004 inch to about 0.002 inch or less for film varying in thickness within the range stated above. Nevertheless the strength of such thin sections necessary for handling the cards is provided by the thermoplastic bonding material. In the case of cards impregnated throughout in the course of manufacture, the thermoplastic material will already be present in the card fibers of the thinned sections before and during the embossing and grinding operations. In other cases where it is preferred to apply the bonding material.
  • thermoplastic bonding material in a strip pattern around the outline of the aperture, a solution thereof can be applied by hand or preferably by mechanical means such as a suitable rotating inking member and a cooperating fountain or other supply of solution, and as this solution dries, the thermoplastic bonding material remains to provide the strengthening effect already mentioned.
  • An additional advantage of the present invention is that because the card surface in the area to which bonding material is applied has been roughened and de-sized by the grinding operation, with the result that the solution quickly penetrates into the fibrous card structure and dries to leave the thermoplastic bonding material not only coated over the ground surfaces but also extending into the fibrous structure of the web, often throughout its entire thickness.
  • the card should be left on the embossing die, or placed on a similar die-like support, while removal of the card material is taking place.
  • this die or support for the bottom of the embossed groove should be high enough so that there will be space or clearance during grinding for card areas beyond the top surface of the Support to depress or fall away from the tool and thus limit its effect to an area corresponding closely in shape and extent with said top surfaces.
  • blank cards embodying the present invention are completed by the application of the solution of bonding materials as already described, preferably to the areas from which embossed material has been removed.
  • the solution for mos-t purposes it is desirable to apply the solution in sufficient quantity to leave a film of solid thermoplastic bonding material on the web surfaces, say 0.0003 inch to 0.0005 inch thick.
  • the blank cards are then ready for storage, sale and/or use for the purposes and with the advantages already explained.
  • the transparency is prepared in any suitable way. For example, it may require edge trimming to the desired shape and size which obviously can be done by hand if desired. In cutting out transparencies from a roll of film or the like, however, suitable die-cutting apparatus, either hand or power operated, will usually be preferred. It will be understood that the film size should be limited so that it overlaps the thin web surrounding the aperture but not the thicker surrounding card.
  • the cards can be fed one by one to a die in position that such operation of the die cuts the aperture with its edges lying in the thinned web of card material to which the bonding material has been applied.
  • Any desired type of feeding mechanism can be used, or the cards can be fed by hand. -For most purposes a simple reciprocating die is satisfactory; it can be operated by hand or foot or by any desired power means.
  • the actual bonding operation may not require heat if provision is made for activation of the bonding material by solvent addition.
  • mild heat in the range of 250350 F., can also be employed for activation of the bonding material, but without substantial softening of the film itself.
  • a hot die having the rectangular shape and size of the perimeter of the aperture and a hot surface approximately /s" wide.
  • this hot surface is brought in contact with the web on the side opposite to that to which the film is applied.
  • the heat passes quickly through the thin web and softens the thermoplastic bonding material next to the film, the rapid heat transfer due to the thin web enabling the use of lower temperatures and/or shorter times. Simultaneous pressure is applied to squeeze the web and film together.
  • the amount of pressure is not critical and can vary widely, say in the range of p.s.i. to 1000 p.s.i. Under these conditions plastic flow of the activated bonding material can take place in forming the bond, but no plastic deformation of the film itself occurs.

  • FIG. 8 shows the completed card with the film mounted therein.
  • a stack of cards to be processed is indicated by the numeral 1 at the left hand side of the figure.
  • these cards may be punch cards of the usual type employed with the IBM system of tabulating card machines, being formed of card stock having a specified thickness of 0.0067 inch with a tolerance of plus or minus 0.0004 inch.
  • the stack of cards can be supported in any suitable magazine from which the cards are fed one by one in succession from the bottom of the stack in the direction indicated by the arrow 2, such feeding mechanisms being well known in the art.
  • the first step according to the present invention comprises an embossing or stamping operation.
  • this embossing operation can be combined with the printing press if desired so that the printed cards leave the press in embossed condition, but as here shown for purposes of illustration, the embossing operation is performed by passing the cards longitudinally in succession between the upper embossing roller 3 and a lower backing roller 4 of rubber or the like.
  • One of the cards is shown at 5 as it passes between these rollers and is embossed in the desired pattern by means of dies 6 carried by the roller 3 at peripheral intervals corresponding with the rate of feed of cards 5.
  • FIG. 1A A detailed diagrammatic view of one of these embossing dies is shown in FIG. 1A. It comprises raised ribs 7 extending circumferentially of the roller 3 and parallel to but spaced from one another, the ends of these ribs being cross-connected by transverse ribs 8 so that the ribs together form a rectangular outline to be embossed on the card 5.
  • the height of the ribs 7 and 8 will obviously be predetermined so as to produce embossing of the desired depth, depending upon the thickness of the film to be mounted and to some extent also on the yieldabili-ty of the rubber backing roller 4. It will be evident that a similar die arrangement can be provided on a conventional reciprocating stamping die.
  • the cards pass from the rollers 3, 4 to a second set of rollers 9 and 10 which accomplish the operation of removing the embossed ridges from the back of the card as described above.
  • the upper wheel 9 carries a series of die-like supports 11 similar in size and shape to the dies 6 of the roller 3.
  • the grinding wheel may be an aluminum oxide wheel running at a surface or linear peripheral speed of approximately 2300 feet per minute, having a wheel grit size of 46-60 and Wheel hardness in the range of G to J (the letters at the beginning of the alphabet indicating softer grades). Of course, these values are not critical; for example, the linear peripheral speed of the grinding wheel may vary between approximate limits of 1800 feet per minute and 3000 feet per minute.
  • the depth of embossing by the dies 6 may be approximately 0.0045 inch, in the case of relatively thick film such as the usual silver halide film which approximates 0.0055 inch.
  • the height of the ribs forming the dies 6 at supports 11 should be somewhat higher, say in the range of 0.006 inch to 0.01 inch.
  • the embossed ridges are removed from the back of the card as explained above, converting it from the condition shown in FIG. 3 to that shown in FIG. 4 and leaving a web thickness of about 0.002 inch.
  • any suitable printing device can be employed. As illustrated diagrammatically in FIG. 1, the cards 5 pass in succession between a backing roll 12 and a printing roller 13 having on its surface suitable solutionaapplying means 14 such as a pad or wick arranged in a pattern to correspond with the pattern or embossing and grinding previously performed. Any known type of solution supply can be employed, and for purposes of illustration FIG. 1 shows an inking roller 15 which rotates partially submerged in a bath 16 of the desired solution and transfers the solution to the applicator means 14.
  • the cards 5 pass to any suitable receptacle here shown as a stack 17.
  • FIG. 3 shows the condition of the blank cards after having passed between rollers 3 and 4.
  • die members 6 create an indented groove 18 on one side of the card and a corresponding ridge-like projection 19 on the other side.
  • the groove 18 may be approximately inch Wide and follows the rectangular outline of the aperture eventually to be cut in the card.
  • the card 5 next passes between the wheels 9 and 10, where its condition progresses to that shown in FIG. 4 wherein the ridge-like projections 19 of FIG. 3 have been ground away, leaving the thin webs 20 forming the bottom of said grooves and connecting the surrounding major H portion of the card indicated at 21 with the rectangular section 22 which is eventually to be removed to form the aperture.
  • these webs 20 may be as little as 0.0015 inch to 0.002 inch, and while they are quite narrow (usually 0.125 inch), nevertheless in the condition shown in FIG. 4 they are too weak for safety in storage, distribution and handling of such cards before the film is actually inserted therein.
  • thermoplastic bonding material by the roller 13, results in some impregnation of the webs 20, as indicated by the stippling in FIG. 5, and also in building up a relatively thin but substantially continuous externallayer of solid thermoplastic bonding material indicated at 23.
  • the inherently weak thin webs 20 are substantially strengthened to withstand all normal conditions of use of the blank cards, including not only manual handling but often the punching of said cards by machine according to desired machine sorting codes, etc.
  • these webs are pushed in by the applicators 14 as shown in FIG. 5.
  • the first operation is to die out the aperture as indicated diagrammatically in FIG. 6 in which a suitable punch 24 punches out the section 22 through an opening in the base 25 by which the card 5 is supported.
  • a suitable punch 24 punches out the section 22 through an opening in the base 25 by which the card 5 is supported.
  • the dimensions of the opening of the base and of the punch are such that the cut is made through the thin webs 20 around the section 22, leaving the major portions of these webs projecting into the aperture.

  • the central part of this support 27 is preferably left hollow or empty. Heat may be supplied to the support 27 in any desired way, as by conventional electrical heating coils 28 which maintain the surfaces of the support at a temperature of say 300 F.
  • the film section can be applied either to the front or back of the card, but preferably is in direct contact with the coating 23 of bonding material which is preferably applied to the ground areas of the back of the card as already stated. This preferred arrangement is shown in FIG. 7, wherein the film, comprising the usual base 29 coated with the usual emulsion 30, is positioned with its edges overlapping the coated and impregnated webs 20. Pressure is then applied by means of any suitable pressure plate 31, simultaneously with the softening of the bonding material by heat supplied through the support 27.
