Definitions

  • Another object of the invention is to pro-' vide a machine which will enable said process tobe carried into practice economically.
  • the problem presents great difliculties by reason of the specific technical conditions which the said cards must satisfy and which are essentially as follows:
  • the cards must be perfectly regular '35 in thickness and must not vary beyond the limits permitted by the various machines in which they are to be utilized, which variation is of the order of one one-hundredth of a millimeter.
  • the length and width of the card are, limited to a Variation-on the order of a tenth of a millimeter.
  • each card must be such as to permit the punching of regular holes at fixed points.
  • Fig. 4 represents a diagram of the testing thereof are subjected to a difierence in poten tial equal to that whichis employed in the machine in which thecards are to be utilized.
  • the 'mechanical resistance of the cards must be such that the cards can safely withstand the friction and shock of the huntng brushes or needles (according to whether the machine operates mechanically or electrically) without danger of tearing or per-- foration.
  • the process forming the subject of the present invention consists in sticking, on one side or the other of the card or simultaneously on both sides of the card, a sheet of material whose characteristics and the mode of fixation will now be described.
  • the material chosen is first subjected to an examination for regularity of thickness.
  • the thickness of the material in any spot must at no time be greater than a value equal to the difference between the actual thickness of the card and a maximum thickness determined by the permissible allowance of the various machines through whichthe cards are to he passed.
  • the thickness of the sheet of material chosen must be sufficient to allow ease of manipulation and to prevent rupture during the passage of cards through the machine.
  • a good thickness in this respect, would be anything between .OQ'and .O-l centimeters.
  • the sheet of material is subjected to an examination for determining the electrical insulating propertiesthereof and only material possessing good insulating properties is chosen. Consequently the material chosen must, in this case, be free of holes, jags or metallic particles.
  • the cards during their travel through the machine, 'must be able to slide easily upon onelanother in order not to drag on the feeding mechanism. 'It follows that the surface of the material chosen must be smooth. In the event that the material chosen only possesses a medium smoothness of surface a thin coat of talc may be subsequently applied to the surface of the rejuvenated cards.
  • the width of the sheet of material chosen must be such that a slight margin will subsist along the correspondin edges of the rejuvenated card in order that the rejuvenated cards will have exactly the same thickness as new cards along the aforesaid edges. Consequently the feeding mechanism of the accounting machine can take new or reand prepared as above described is stuck juvenated cards indiscriminately without modifying its adj ustment.
  • said margin along both edges may be in the neighborhood of 1 millimeter but may be reduced to a much less value if desired.
  • the liquid paste employed must be specially prepared as it must be very homogeneous in character in order to prevent over-thick lumps which would interfere with the rejuvenated card passing properly through the machine in which it is used.
  • the paste chosen must also possess the property of drying rapidly and at the same time produce perfect adherence.
  • the sheet of matcrial chosen must in no spot be greater than acertain maximum value determined by the thickness of the card and the clulmcteristics of the machine in which it is to be used. It frequently happens that the actual thickness of the card is very near that of the maximum allowable thickness of the machine in which it is used. I In such a case the material chosen is of a thickness greater than that previously indicated and the pasted card is subjected to a rolling operation which pushes back the sheet of pasted material into the body of the card in such a manner as to form a practically negligible thickness in the rejuvenated card.
  • the maximum allowable thickness imposed upon the sheet of material does not give it suflicient mechanical strength, it is reinforced by filling the holes in the card with a cement or putty which will strongly adhere to the internal surface of the sheet or sheets of material employed.
  • the cards to be rejuvenated are placed in a feeding receptacle 1 and are extracted therefrom by means of a suitable feeding mechanism 2 of known type which pushes the said cards one after another and in abutting relation through a pair of premure rollers 5.
  • a suitable feeding mechanism 2 of known type which pushes the said cards one after another and in abutting relation through a pair of premure rollers 5.
  • the paper material is rolled upon a roller 3 and passes over a paste roller 4 and then between the pressure rollers 5 where it is continuously pasted upon the cards passing through the saidpressure rollers.
  • putty or cement is inserted therein by means of a mechanical mechanism of known type which will automatically perform the puttying operation, that is the filling of the holes to be closed and the scraping order to enter readily between the cards in side of the card but before the pasting takes.
  • the cards covered with the paper pass between a series of heated rollers 6 venated cards and maintain their straightness.
  • the rollers 6 may be heated by a current of air heated with electrical resistances which current of air would also contribute to the drying of the card.
  • the rejuvenated cards then pass between a series of laminating rollers 7 which press the sheet of paper material A (Fig. 3) into the body B of the card in such a manner that the increase in the thickness of the rejuvenated card is substantially negligible.
  • the continuous string of rejuvenated cards thus formedpasses through a separating mechanism 10 provided with a cutting blade 10.
  • the cards used in accounting machines generally have cut off corners, i. e., bevelled edges 12 (Fig. 2) which gives rise to a notch 8 between adjacent cards along the entire edge of the continuous string of cards.
  • a friction roller 9 is adapted to bear against the edge of the string of cards by means of a spring 9 and each time the said roller moves into a notch 8 it causes the blade 10 (Fig. 1) to descend and separate successive cards as they pass, the said blade being very thin in abutting relation. The finishedcards finally fall into a receiving bin 11.
  • the punched cards first have applied to their under side the paper from roll 3 by rolls and then pass under a reservoir 24 for pasty filling material or putty.
  • This material in the reservoir is under pressure of a column of water orother fluid conducted to the reservoir through a pipe
  • the filled cards then pass between pressure rolls 19 that apply a strip of paper to the upper face of the cards from a roll of paper 20.
  • the cards faced on both sides with a. strip of paper pass to the cutter and fall into the bin 11.
  • the apparatus for testing the finished cards is shown .in Fig. 4 and comprises a receiving receptacle 12 arranged exactly the same as that upon the machine in which the cards are to be utilized. At the lower part, the said receptacle is provided with a mechanism 13 destined to take the cards one by one. When the cards have been tested as to their feeding qualities by the said mechanism they subsequently pass between a series of brushes 14' disposed on the upper side of the'passing card and connected to a source of E. M. F. 15. The card moves over a flat metallic surface for drying the reju-- 17 which is carried by an electrically oper-- ated mechanism 16. The other terminal of said source is connected to a terminal of the mechanism 16 and the other terminal of said mechanism is connected to the plate 17 thereof. The said mechanism 16 is adapted to move the plate 17 downward when current passes therethrough.
  • the voltage of the source is such that a difference in potential is maintained between brushes 14 and plate 17 which is superior to that maintained in the machines in which the cards are to be utilized.
  • a process of rejuvenating used, punched accounting machine cards which comprises feeding the cards onto a continuous web, narrower than the cards and previously supplied with adhesive, rolling the web onto the body of the cards and severing the web between the cards.
  • a process for rejuvenating bevelled and punched used accounting machine cards which comprises feeding the cards inabutting relation onto a continuous web previously supplied with adhesive, drying and pressing the web with the cards thereon and severing the web between the abutting edges under the control of the adjacent beveled edges.
  • a process for rejuvenating bevelled and punched used accounting machine cards which comprises feeding the cards onto a continuous web narrower than the cards, successively in abutting relation, previously supplying the web with ahomogeneous paste having the same shrinking characteristics as the web. drying the web with'the cards thereon, compressing the web to countersink the web in the cards and severing the web between abutting cards.
  • a process for rejuvenating used bevelledand punched accounting machine cards which comprises feeding the cards in abutting relation onto a strip of cellulose muslin previously supplied with adhesive .having substantially the same shrinking characteristics as the muslin, drying the strip with the cards thereon, rolling the muslin into the cards to countersink ittherein, and severing the strip between the abutting edges of the cards. 5 6.
  • a process of rejuvenating used bevelled I and perforated accounting machine cards which comprises feeding the cards in substantially abutting relation onto a continuous strip of cellulose muslin previously su plied with an adhesive having substantial y the same shrinking characteristics as the muslin, drying the strip with the cardsthereon, counter-sinking the muslin in the cards by pressure and severing the strip between the abutting edges of the cards under the control of their abutting edges.
  • a process of rejuvenating used, bevelled, perforated accounting machine cards which comprises supplying the cards in substantially abutting relation onto a strip of material previously supplied with an adhesive having substantially the same shrinking characteristics as the strip, filling the holes with a putty, applying a second strip on the opposite face of the cards, drying the strips with the cards between them and severing thedstrip between the adjacent edges of the car s.
  • a previously used and punched card for accounting machines having a sheet of material on a face and its holes filled with a. putty.
  • a previously used and punched accounting machine card having its holes covered with a sheet of material narrower than the card and countersunk therein.
  • a previously used and punched accounting machine card having its holes covered with a sheet of material countersunk in the card and the holes filled with putty.
