APPARATUS FOR MANUFACTURING FILM RECORD CARDS Filed June 15, 1966 2 Sheets-Sheet 2 United States Patent O 3,410,162 APPARATUS FOR MANUFACTURING FILM RECORD CARDS Henry A. Ruggeri, Springfield, Mass., assignor to United States Envelope Company, Springfield, Mass., a corporation of Maine Filed June 15, 1966, Ser. No. 557,777 9 Claims. (Cl. 83-100) ABSTRACT OF THE DISCLOSURE In a film record card making machine a patch of film material is applied to a card passing between two rolls, one of which is a vacuum roll. The patch is cut from a web feed to the vacuum rofl at a speed slower than that of the roll and means are provided on the roll to prevent scratching of the web due to slippage between the roll and web. A cut off blade carried by the vacuum roll is also so arranged as to prevent scratching of the web.

This invention relates generally to apparatus for manufacturing film record cards, and more specifically, this invention relates to apparatus for permanently associating, at high speed, patches of film with individual record cards adapted to receive the film.

Record cards are commonly in use in connection with electrical card handling machines for the filing and storage of certain information, data, etc. Such record cards are sometimes used for the storage of microfilm, both un developed and developed. The microfilm is normally affixed to a record card over an opening therein. Cards having the undeveloped microfilm may be used for making copies of the developed cards stored in a master file.

The present invention is principally concerned with taking the microfilm material in roll form, cutting patches of predetermined size from the roll strip, and permanently aifixing the so-cut patches to record cards which are advanced in continuous motion through the machine.

The basic process of affixing the patches of film to record cards is, in some ways, analogous to affixing patches of transparent material to the windows or openings of envelope blanks. Various types of apparatus have been developed in the past for applying a patch of transparent material over openings in envelope blanks. For example, in the manufacture of so-called window envelopes, it is common practice to advance unfolded envelope blanks successively along a horizontal path, first cutting the opening in the blank, and then afiixing the patch of transparent material over the opening. An example of such a method and mechanism is the patent of V. E. Heywood, No. 2,953,071, entitled Manufacture of Window Envelopes, issued Sept. 20, 1960.

Basically, the method and mechanism described in the Heywood patent should be satisfactory for affixing film patches to record cards. However, the film material, which is commonly of a material such as acetate, tricite, triacetate, or the like, having a coating of photosensitive material, is so delicate, and is so easily scratched, that extreme care is required during handling. If the film, or coating, is scratched even microscopically, the usefulness of the film becomes seriously impaired.

The advantages of the method and mechanism of the Heywood patent are many, and will not be repeated herein in detail. Suffice it to say that basically it provides an extremely efiicient, speedy, and accurate method and apparatus for affixing patches of material cut from a web over the openings of the blanks. Delicate material, however, has been found to receive serious scratches from parts of this mechanism. On the tougher envelope window "ice material, however, no scratching problem is encountered.

It is, therefore, an object of the present invention to provide mechanism, of the general type disclosed in the Heywood patent, for handling delicate material, thereby overcoming the problem encountered with common types of mechanism for affixing patches of material to a carrier.

It is another object of the present invention to provide mechanism for handling such material in an etficient, speedy, and accurate manner.

Other and further objects and advantages of the invention will become apparent from the following detailed description thereof, taken in connection with the accompanying illustrative drawings in which FIGURE 1 is a side elevation view, partly in section, of mechanism embodying this invention.

Referring to the drawings in detail, in FIGURE 1, a continuously moving high-speed succession of record cards C (shown in broken lines) passes from the right to the left between the various opposed rolls which are illustrated in the lower portion of this figure. At the same time, a web P of film material is drawn at constant speed from a large supply roll v10, around a guide roll 12, by its passage between a pair of contacting feed rolls 14 and 16. The web P passes thence from left to right, first beneath a rotating gum applicator 18, and then onto and embracingly around a constantly rotating vacuum applicator roll 20, to be described in detail hereinafter. The surface speed of this roll 20 is substantially the same as the card speed, and the card patch is tangent to said rolls surface at a point 'which is almost distant from the web materials initial contact with said surface. As the subtended length of slower speed web P moves along this right-hand half of the vacuum rolls surface (in the slip-draft manner later to be described), knives 22 and 24 will cut successive patches from the web. Immediately after each patch is cut, roll 20 will apply this pregummed patch at high speed to that record card which is then passing at high speed between the bite of vacuum roll 20 and its associated underlying platen roll 26.

Cards C are advanced from right to left as viewed in FIGURE 1, being fed in timed, spaced succession into the first set of feed rolls 28 and 30 from hopper feeding means (not shown) or some other suitable feeding means. The cards C are then fed and held in alignment by the upper and lower feed rolls 32 and 34. Openings are cut in the interior of the cards by the punch and die rolls 36 and 38 respectively. Cards C are thence fed through the feed rolls 40 and 42, into the patch-applying roll 20 and 26. Cards C continue in their spaced progression through the feed rolls 44, 46, 48, 50, 52 and 54, and are finally discharged from the left-hand end of the machine onto a take-away conveyor (not shown), or the like, for packing. It should be understood that means for feeding the cards in spaced, timed relationship may be carried out by other means, e.g., a lug-chain appartus, and is not limited to the feed-roll arrangement illustrated in the drawings. The feed-rolls are illustrated only for the purpose of simplicity, and do not form a part of this invention.

The film web is fed out continuously from the supply roll in predetermined amounts sufficient to provide a certain size patch for each card being processed, or passed through the machine for patching. The feed rolls 14 and 16 control the amount of film web fed or metered out. The film web P passes a gum applicator roll 18 which is provided with land areas 56 and 58 which pick up adhesive from reservoir roll 60 rotating in communication with the interior of gum tub 61. Patterns of adhesive are printed on the film web P at predetermined positions so that each piece subsequent-1y cut from the end thereof has a pattern of adhesive for causing the piece to be adhered to its mating record card. It should be understood that, if desired, the machine may be designed such that the cards C, rather than the film patches, receive the adhesive pattern. For purposes of illustration, however, applicant has chosen to show the adhesive being applied to the tfilm web P. In this case, the adhesive applicator roll 18 applies the adhesive to the Web P against the backing plate 62, which is adjustable to and away from the applicator roll 18.

From the adhesive applicator roll 18, the web P of film material is directed to the upper surface of vacuum applicator roll 20, which is rotating at the full-line speed of the record cards C passing through the mechanism. As best shown in FIGURES 1 and 2, this roll has a plurality of inner, longitudinal channels 64 which are closed at one end of the roll 20, but which open at the rolls other end against the inner face of a stationary vacuum distributor (not shown), concentric with the roll. The distributors inner face provides, in the path of the several channels open ends, an opening which is connected with the vacuum source. This distributors opening is substantially co-extensive with the web-contacted righthand half of the roll 20, thereby to establish the access of suction to all the channels which at any given instant are occupying a position to the right of the vertical centerline of roll 20. Channels 64 communicate with the outer surface of the roll by means of a plurality of spaced holes or ports 66 extending substantially radially outward from each of the channels 64, along the lengths thereof. Under this arrangement, the right-hand portion of the surface of the vacuum applicator roll 20, or, in other Words, substantially the portion in contact with the film web P, will always be under light vacuum.

Since the peripheral speed of vacuum roll is considerably greater than the linear speed of the web P of film material, as metered out by the slower speed feed rolls 14 and 16, the length of web material on the righthand half of roll 20, though held closely by suction in the rolls surface, will be in constant slip-draft relationship to said rapidly rotating surface; the vacuum pull will hold the web against the right-hand surface of the roll while this relative slipping, or dragging effect occurs. Then, the web P will travel in a clockwise direction over the surface of the vacuum applicator roll 20 in a close fitting and slipping relationship until the foremost portion is severed from the web by the blade 24 of the rotating cutter roll 21. This severed portion, released from restraint imposed by the film webs slower feed rolls 14 and 16, will immediately assume full line speed of the vacuum applicator roll 20 against which it is held by the force of the vacuum, and as it does so, begins tocontact and stick to the card C which, because of its timed progression relative to rotation of roll 20, is directly thereunder, with the portion adapted to receive the patch in position.

Both the structure and operation of the mechanism described above are basically similar to that described in full detail in the above-mentioned Heywood Patent No. 2,953,071, and will not be again described in detail here, except for the part pertaining to the present invention, i.e., the vacuum applicator roll 20.

In the Heywood mechanism, there are two conditions which cause serious scratching of the delicate film web, i.e., the blade of the vacuum roll is in sliding contact with one side of the film web from the point of initial contact to the cutoff point (point where the knife blades meet), and is about Minute irregularities in the edge of the blade which must slide under the web (drawn tightly over the blade because of the vacuum in roll) is a primary source of the scratching. Another primary source of scratching is the plurality of vacuum holes in the applicator roll. The vacuum has a tendency to pull the film partially into the holes, and as the applicator roll is moving at a faster peripheral speed than the advancement of the web, the film must slide continuously in and out of the vacuum holes. Minute irregularities naturally occur in the junction between the outer surface of the roll and the radially extending vacuum holes. It will be noted that vacuum is not evenly distributed to the underside of web because the vacuum acts only at the holes, and a relatively large amount of land area is subjected to no vacuum at all.

The present invention provides means for overcoming the conditions mentioned above which cause the serious problems in scratching theusable surface of the film.

According to this invention, the applicator roll 20 is made of a configuration such that the film Web P is firmly supported radially beyond the cutting blade 22 on each side thereof during the time the roll 20 is in sliding contact with the web P, and by providing the web-supporting surface of applicator roll 20 with a multiplicity of smoothly rounded and spaced apart land areas having vacuum communicating channels between the land areas.

Referring especially to FIGURES 2-5 inclusive and FIGURE 8, the web supporting surface area of applicator roll 20 is covered with a porous screen or fabric 70 (FIGURES 2, 3 and 8), or the surface has been finished, as illustrated in FIGURES 4 and 5, to provide a multiplicity of smoothly rounded and finished land areas 72. The land areas 72 act to support the film web P, and interconnecting vacuum communicating channels 74 serve to distribute the vacuum from holes or ports 66 over a relatively large portion of the surface area of the applicator roll 20. In this manner, there is no concentration of vacuum acting on a relatively small area of the web P. The vacuum is evenly distributed over a substantial area of the film web P. The film web will gently conform to the smoothly rounded land areas 72 of the vacuum applicator roll 20. It is not subjected to the action of sliding past sharp edges of the bare vacuum ports 66. The smoothly rounded and finished landportions may either be integral with the roll, or, if not integral with the roll, firmly afiixed thereto.

FIGURES 2 and 3, illustrate a preferred form of the invention where a piece 70 of porous screen, fabric, or the like, penetrable by vacuum, has been placed over the surface of the roll 20. Screen of fabric is found to have a multiplicity of minute land areas which serve to support the film web, and interconnecting vacuum communicating channels which serve to distribute the vacuum from the holes 66 over a relatively large portion of the surface area of the applicator roll by the porous nature thereof. Examples of suitable screen material include Fiberglas and plastic material. Examples of porous fabrics which have been found suitable include nylon, silk, and velvet. Undoubtedly, there are other suitable materials, and these materials are only mentioned as examples. What is important, however, is that there be a smooth surface of closely spaced land areas and vacuum communicating channels between the land areas, such as that found in a screen or vacuum-penetrating fabric.

FIGURE 8 illustrates the manner in which the screen or fabric may be fixed to the vacuum applicator roll 20. Also, FIGURE 8 illustrates a slightly different form of the invention, wherein two layers of material are afiixed to the surface of roll 20, the layer 76 next to the rolls surface being a coarse-mesh screen, and the outer layer 78 being a relatively fine-mesh fabric. In this instance, the underlying layer 76 of coarse-mesh screen provides means for effectively distributing vacuum from the holes 66 over almost the entire underside of the vacuum-penetrating fabric 78. The fabric, however, provides an almost solid support for the film web P, but still porous enough for vacuum to penetrate. The soft fabric also provides a very smooth surface over which the film web may slide. It should be understood, however, that it is not necessary that both the screen 76 and fabric 78 be used in combination, as shown in FIGURE 8. FIGURE 8 only illustrates that it is within the scope of this invention to use both in combination. The screen fabric, or the combination of both may conveniently be aflixed to the roll 20 by means of the clamping bars 80' and 82 fitted in the longitudinal slot 84 on both sides of blade 22.

Referring now especially to FIGURES 6-8 inclusive, cutter blade 22 is mounted in vacuum applicator roll 20 by any suitable means. Cutter blade 22 is mounted, however, such that its cutting edge 86 is below the effective periphery of the roll, or, in other words, such that its cutting edge 86 will be inside a chord struck between the two adjacent edges 88 and 90 of the roll. As best seen in FIGURE 8, the film web P, when stretched between these two edges 88 and 90, will be spaced from the edge 86 of blade 22. The web P will actually form a chord extending from 88 to 90. Cutter blade 24 projects beyond the imiginary circumference 96 which would be tangent to the circumference and concentric with the central axis of cutter roll 21. Since the edge 86 of blade 22 is below the circumference of roll 20, a small amount of open space is left on both sides of blade 22 to prevent the blade 24 from contacting the roll adjacent knife 22. It is apparent that the amount of space left open in this area is dependent upon several variables, i.e., the relative speed, relative roll diameters, and relative pitch diameters of the cutter blades 22 and 24. In the drawings, roll 21 is designed to rotate twice for every revolution of roll 20; hence, the flattened spot 98 in the roll 20 prevents the blade 24 from contacting roll 20 at this location.

FIGURES 6 and 7 have omitted many of the details of the vacuum applicator roll 20 for the sake of simplicity. These figures illustrate, however, the manner of cutting successive pieces from the end of film web P. FIGURE 6 illustrates the relative position of the cutter blades 22 and 24, as well as the web P held snugly to the surface of roll 20, at a point less than 90 from cutoff. FIGURE 7 illustrates the relative position just at the point of cutoff. It will be seen that in the illustration the cutter blade 22 is in contact with the film web P for a very slight distance just prior to cutoff. The amount of contact is a function of relative blade pitch diameter and relative speed of rolls 20 and 21. This is not seen to cause serious scratching of the film web because any scratching which occurs will be immediately adjacent to the cutoff, and, therefore, within' the area of where the film and card overlap for connection, and not in the useful area of the film.

FIGURE 9 illustrates a film record card C which may conveniently be manufactured by apparatus in accordance with this invention. Patch 100 is firmly aflixed to card C over opening 102. If desired, the area around the opening 102 defined by line 104 may be depressed, or the card thickness in this area may be reduced, so that the film patch 100 may be flush with the surface of the card C.

It will be understood that various changes in the details, materials, steps, and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the scope of the invention as expressed in the appended claims.
