APPARATUS FOR CUTTING AND MOUNTING FRAMES OF ADHESIVE-COATED MATE- RIAL N CARDS Ohio, a corporation Application December 28, 1948, Serial No. 67,713

This invention relates to apparatus for punching out frames of adhesive-coated material and mounting the frames on statistical cards or the like in registry with die-cut openings formed in the cards.

In the use of statistical cards and the like, it is frequently desirable to combine with the card a microfilm of a, record or other information pertinent to the card. This may be accomplished by providing each card with a die-cut opening and mounting a microfilm exposure within the opening. Thus, when it is desired to read the information on the microfilm, the card may be inserted in a suitable projection apparatus for reading the microfilm.

In mounting microfilm exposures in die-cut openings in statistical cards and the like, it is a common practice to mount on one side of the card, in registry with the die-cut opening, a rectangular frame of glassine or other suitable material coated on one side (facing the card) with a pressure-sensitive adhesive. Such rectangular frame overlaps the edges of the die-cut opening, and the microfilm exposure is mounted on the overlapping portions of the frame.

One method of performing the operations described above comprises feeding a strip of adhesive-coated material between a die plate having a die opening formed therein and a punching die, and actuating the punching die to punch out a frame of adhesive-coated material from the strip and to mount the frame on a card in registry with a die-cut opening formed in the card. In carrying out this method, difliculty results from the fact that the strip of adhesive-coated material has a tendency to adhere to the die plate, thus interfering with the speed and continuity of operation.

It is an object of the invention to provide a means of overcoming the above-mentioned difficulty.

This and other objects of the invention will be apparent from the ensuing description and the appended claims.

Certain forms which the invention may assume are exemplified in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a view, partly inside elevation and partly broken away, of one form of apparatus of the invention.

Fig. 2 is a fragmentary, sectional view of another form of apparatus of the invention.

Referring now to the drawings, and more particularly to Fig. 1, one form of apparatus, generally designated as It, is illustrated which embod- 3 Claims. (Cl. 16487) ies the improvements of this invention. This apparatuts is adapted to punch out rectangular segments from a strip of adhesive-coated glassine, to mount the same upon a card, to punch the card and to perform an inner punch on the mounted segment of glassine. A novel and useful article is thus produced which is described and claimed in our copending application, Serial No. 67,712, filed December 28, 1948 entitled Apparatus and Method of Cutting Adhesive Material and Mounting the Same Upon a Card.

This apparatus comprises a frame or housing I l containing within a card punching mechanism l2 and without, a frame punching mechanism IS. The card punching mechanism, briefly, comprises a punching die l4 reciprocable in an opening Iii formed in a card supporting plate I6 upon which a card I! is supported and is aligned by means of guide members I8. Springs I9 normally hold the die I4 in retracted position, and the die is actuated by means of a lever and arm 29 to punch a card [1.

The frame punching mechanism comprises outer and inner dies and 26, the outer die being reciprocable in a frame 2? and held in retracted position by a spring 28, and the inner die 26 being reciprocable in the outer die and held in retracted position by a spring 29. A die plate 39 having a die opening 3| is provided, being spaced from the frame 2'! and dies 25 and 26, to provide a feed throat 32. The dies 25 and 26 are actuated by the lever 20 through the medium of levers 33 and 3A, a link 35 and an arm 36.

A strip of adhesive-coated glassine is supplied to the dies 25 and 26 in the manner hereinafter described, and when the lever 20 is depressed a rectangular segment of glassine is punched from the strip and deposited on the card I? and is punched again to form an inner and smaller rectangular segment. Further details regarding the apparatus as thus far -described, the operation of the punching dies 14, 25 and 26 and the nature of the article produced are set forth in the copending application abovementioned.

As indicated, the adhesive-coated glassine 40 will have atendency to adhere to the die plate30, thus interfering with operation of the machine. To obviate this tendency, a feed means is provided which will now be described.

The glassine 40 is available in the form of a roll of laminar tape 4| comprising a glassine layer 40 and a layer of backing 42. This tape is supported on a reel 43 rotatably supported on a bracket 44. The backing is peeled in the usual manner by means of a stripper plate 45 and a drive roll 46 rotatable by means of a knob 41. The peeled glassine is fed through the feed throat 32, and the resulting ladder 48 of waste is taken up by a, take-up reel 49 rotatably mounted on a bracket 50. The take-up reel is driven by a knob 55, and the

reels

43 and 49 may be synchronized and the feeding of the tape indexed by any suitable means well known in the art.

As illustrated, rollers 56 and 5'! are rotatably mounted on the frame 21 on opposite sides of the punching dies, and the

reels

43 and 49 are disposed with their axes above the feed throat 32. It will thus be apparent that the glassine strip 40 and ladder 48 will always be held taut against the rollers 56 and 51, and that when the dies 25 and 26 are actuated they will stretch the glassine. When the outer die 25 has completed its punching operation and is moving the punched segment of glassine down through the die opening 3|, the adhesion of the glassine to the surface of the die plate 30 will be opposed by the tension of the glassine. This tension, arising from its stretching, will sufice to lift or snap the glassine back to its normal position and free it from the die plate 38 in ample time for the next increment of movement of the tape 4|.

Referring now to Fig. 2, the construction there illustrated is similar, but a collar 68 carrying the rollers 56 and 51 is mounted on the outer die 25 so as to move therewith, and the upper die assembly is reciprocable in a frame 8 I. It will be apparent that when the dies 25 and 28 are actuated, the rollers 56 and 5'! will carry the glassine strip 48 and ladder 48 down onto the die plate 30, and that when the dies return to their normal, retracted position the pressure of the rollers will be removed and the tension of the glassine will restore it to its normal position clear of the die plate.

It is thus apparent that an apparatus has been provided which is operable to punch segments or frames of adhesive-coated material from a strip thereof and to mount the segment or frame on a card or the like, and that a disadvantage of prior devices of this character is obviated, in that the strip and ladder of material are cleared of the die surfaces in ample time for the next cycle of operations.

While we have shown the preferred forms of our invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described our invention, what we claim and desire to secure by Letters Patent is:
