The invention relates to display signs of the kind which are exposed in store windows or other conspicuous places, being propped up against surrounding objects or more frequently provided with a wing by which they are supported at an angle slightly deflected from the vertical so that they remain in stable equilibrium.

In accordance with the existing practice, a

portion of the display cards or signs used are printed on cardboard by means of a cylinder press, but on account of the necessity for rolling the cardboard or bending it about the cylinder there is a very definite limit to the thickness of the material which can be used, and for this reason only the comparatively small cards have been printed in this way, as the material is not stifi' enough to stand up when embodied in a medium or large sized display card. The larger display cards or signs have been produced by printing or lithographing, on thin paper mounted on thick cardboard which is sufiiciently stiff to stand on edge, but the large display cards produced in this way are often not satisfactory, as they tend to warp and curl after the' first day or two and do not present an attractive appearance, and even the smaller cards produced in this way or by printing directly on the card are more or less subject to the same difficulty.

The invention relates to a methodof producing display cards which can be printed directly on the cardboard with complete satisfaction by means of a cylinder press and completed in such a manner that they are per-- fectly flat when finished and set up when placed in a substantially vertical pl-ane they are capable of retaining their flat condition almost indefinitely and under any circumstances for a period amply sufiicient for the purposes in handas the average display card is used for only a few Weeks.

In accordance with the invention the display cards are printed directly on cardboard of a thickness which can be conveniently handled in a cylinder press and immediately after printing or at any time they are cut partially through from the front side parallel to the edges forming a hinged marginal portion which is caused to turn backwardly substantially at right angles to the plane of the cardboard. This brings the display card to a perfectly fiat condition and permits it to be supported in upright position for sever'alweeks or almost indefinitely without any tendency to change its fiat shape or configuration. 1

The production of display cards of the H large sizes and of sufficient rigidity to present a satisfactory appearance by retaining their fiat contour for even a short period when in use, has been exceedingly expensive on account of the elaborate apparatus necessary to mount the paper on which the subj f.

matter of the display card is printed, or more frequently, lithographed, on the cardboard backing or mounting which serves as the sup-1 port orbody of the card. The apparatus involves an investment of many thousand dollars and the time required to produce the display cards in this'way results in'a considerable expense in labor in addition to the cost of the material which is excessive on account of the necessity for a thick heavy card, that ordinarily used being of the quality known as point, i. e., .100 in thickness or ,A still heavier paper board is also supplied for this purpose. As a result of these conditions large display cards are too expensive for many purposes for'which they might be used. On the other hand, the cardboard used in the improved display card may be no thicker and hence not more expensive than that previously used for small display cards 14 x 18 and less. Forlsuch cards made in accordance with the previously existing practice, 48 point, i. e. 14E. ply is considered very heavy and is printed with great difliculty. By means of the presentprocess a display card of an area of 3 x 4, or even larger, the average large card being about 30 x 3, can be made of 28 point to 48 point cardboard, i. e., .028 to .048. This issuf ficiently stiff to stand without buckling for a period of several weeks or even more, a life of two weeks being satisfactory for the. average display card. This relatively thin material can be easily printed on a cylinder press such as is possessedby almost every I printer, thus opening the display card business to the average printer, reducing the price of these large display cards and increasing the demand for them with corresponding benefit to the printing trade in general. This increase in the demand contributes in turn to an increased demand for the cardboard which will be of great benefit to the mills producing this material.

Such cards can be made of any convenient or desired area from the very small cards to those of eight to twelve square feet in area. 7 The invention relates to the method as thus outlined and hereinafter more particularly described, and to the product in the form described of a perfectly flat self sustaining, self reinforced display card printed directly on the cardboard and consistmg of a single piece of cardboard.

In the accompanying drawings I have lllustrated a display card made in accordance with the invention, and I have also shown diagrammatically a machine by which the method of the invention may be practiced, although the invention may be also performed by other apparatus or by hand, the apparatus itself forming no part of the invention,

Referring to the drawings by numerals, each of which is used to indicate the same or similar parts in the dilferent figures, the

display card 1 shown in Figure 1 is preferably of rectangular outline, having printed V on its front face the subject matterto be displayed indicated by reference character 1; The display card, as shown, has its edges cutpart way through, as indicated in Fig ure 6, on lines 2, 3, 4;, 5 parallel to the corresponding edges 6, 7, 8 and 9. The cut's2, 3, 4

and 5 are spaced back from the edges by a suitable 1nargin.. This margin in the preferred form particularly adapted to the production of large display cards may be about The marginal portions thus partially severe-d, and of the width named or any suitable width, are indicated by reference characters 10, 11, 12, 13. In the operativep-osition of the display card, these edges are pref in any suitable manner so long as the stiffen ing effect is obtained by hinging the edges and turningthem, preferably without the use of other stiffening means in the form of separate members. The drawings, Figures 2 3 and 8, show a folding wing support 15.

by which the card is caused to stand on edge in a near vertical position. This support in the form shown, the wing not being rcgarded as essential to the invention, consists of two strips of cardboard or the like, 16'and 17, attached to the back of the display card 1 in any conve'nientmanner as. by means of cement or glue. The strips'16, 17 include a base portion 18 thus secured to the back of the display card and a wing portion 19, which is hinged by creasing, or otherwise adapted to be folded flat against the back of the card when not in use or held at right angles there-.

to as by mean's of hinged flaps 20 which are centrally slotted at 21' to straddle the wing 19. hen the flaps 20 are turned at right angles to the display card 1, straddling the,

wings or fins 19 which must be substantially at right angles to the card 1 to accomplish this function, they serve to hold the wings in their right angular or other operativep sition. To fold the fine or wings19 flat the flaps 20 which arepreferably cut out'of the material forming the strips 16 an-d-17, are folded flat against the back of card 1 releasing the fin or Wing 19.

In the practice of the method of the invention a sheet of cardboard preferably of the coated calendered variety and of a thickness such that it can be easily run through a cylinder press in a satisfactory manner, preferably from 28 to 48 point, i. e., .028 to .048 of an inch in thickness, is printed with the desired subject matter to be displayed. For this purpose it is in accordance with the preferred practice run through an ordinary cylinder press of a construction well known to those skilled in the printing art and indicated diagrammatically in Figure 9 as consisting of a cylinder 25 and a reciprocating printing plate 26, and guide 25. This plate at the time of printing is set with suitable type indicated by reference character 27.

After printing the card is again passed through the press to cut the edges partially through as indicated at 2, 3, 4, 5 in Figure 6 along lines corresponding to the edges 6, 7 8, 9 and spaced therefrom by a suitable margin to form the supporting fins 10, 11, 12, 13.

This may be accomplished either by removing the type 27 from the plate 26 and replacing it by cutting members otherwise known as printers rules 28, spaced or ar ranged in relation to the size of the display sign being produced, as already explained, and as indicated in Figure 12. On the other hand, if the display cards are being produced in large quantities, it may be found desirable to provide a continuous machine instead of running the cards through a single cylinder machine, first printing them and then rearranging the machine for cutting. To form such a continuous machine, the machines in Figures 9 and 10 may be combined in any suitable manner. While the steps of the method are preferably performed in the order named, it will be understood that they may be performed to somewhat less advantage in the reverse order. When the cards have been thus printed and cut and the wings 15 aflixed, the display cards are ready to be packed and shipped.

To this end the edge fins 10, 11, 12, 13 are folded fiat against the back of the card. The wings 15 are likewise folded and the display cards with the flattened edge are packed one on top of the other in a corresponding flat carton, it being understood that the steps being described comprise the preferred method, many of the steps and details being regarded as essential to the invention in its proper conception.

lVhen the display cards are unpacked, the edge fins 10, 11, 12, 13 being freed, spring outwardly to a position nearly at right angles assuming by the natural resilience of the material forming the hinge portions beneath the cuts, aiposition in which the fins 10, 11, 12, 13 support the body of the display card in the desired-flat condition. f

In this connection it should be understood that the display card of. the invention is What may be termed self supporting, i. e., the stiffening members or fins 10, 11, 12, 13

are each an integral part of the printed sheet of vcardboard from which the display card is made, partially severed, forming hinges so that the fins .can be turned backward to the desired angle and the display card in the preferredform includes no other supports or stiffening members.

By the practice of the invention, display cards of the large sizes named. or of any size.

are made by printing-on the common cylinder press, using this cardboard which is easily printed in this way and-wh1ch previously could not be used for any but the small cards.

While 48 point, i. e., (.048 or 14 ply cardboard is available when printed with suflicient skill and care, still thinnermaterial l which is more easily handled in printing is adapted to this purpose down to about 28 point (.028), for large cards and down to about .008 for the smaller cards.

, As already pointed out, the production of display cards in accordance with the improved method whereby they can be produced much more cheaply and quickly-than hithertofore,.opens up a new field to a large number of printing establishments, greatly reduces the'cost of the large display cards and creates or tends to create a largely increased sale of such cards and hence an increased demand for the quality of cardboard utilized in this Way.

I have thus described specifically and in detail a display card and the method of producing the same embodying the features of that the manner of constructing, applying, operating and using the invention maybe fully understood, however, the specific terms herein are used descriptively rather than in a limiting sense, the scope of the invention being defined in the claims.
