PRINTING Filed NOV. 3, 1934 fizz/w Gan 01d; ,By W. 57m W W Patented Sept. 1, 1936 PATET OFFICE PRINTING Application November 3, 1934, Serial No. 751,269
2 Claims.
The present invention pertains to printing, and has particular reference to the printing of materials such as transparent cellulose sheeting in which the inherent characteristics of the material are such as not to adsorb ink readily.
In printing adsorbent materials the problem of offset is not serious, but as the adsorbent characteristics of the printed material decrease, it becomes necessary to take special precautions in the prevention of offset or smearing of the ink, particularly where the inks employed are relatively slow drying. Many gravure inks are sufi'iciently volatile that the webof relatively nonadsorbent material may be printed and immediately rewound without offset. Inks having slower drying solvents, such asoil inks and. the like, when deposited on non-adsorbent materials must be handled with care to prevent smearing.
A particular object of the present invention is to provide an improved method and an improved device for printing relatively non-adsorbent material such as transparent cellulose sheeting with relatively slow drying ink in such a manner as to prevent oifset or smearing of the ink.
' An additional object is the provision of an improved package or container for printed ma.- terials of the type described.
These and other objects will be evident from a consideration of. the following description of a preferred embodiment of my invention and by reference to the accompanying drawing, in which Fig. 1 is a perspective view of a device constructed in accordance with my invention;
Fig. 2 is a sectional view taken through the longitudinal center of the device shown in Fig. 1 and showing the device in rolled condition;
Fig. 3 is an enlarged sectional view taken along line 3-3 of Fig. 2;
Fig. 4 is a view similar to Fig. 2 and. shows the device of Fig. 1 rolled oppositely from Fig. 2;
Fig. 5 is a view of a reel upon which the device shown in Fig. 1 may be Wound; and
Fig. 6 is a diagrammatic view showing the printing of a web of material and the rolling of the web with the device shown in Fig. 1.
Heretofore transparent cellulose sheeting has been printed with relatively slow drying inks and the printed web re-rolled with sandpaper until the ink is dry. While this method is satisfactory in many respects, particularly for relatively wide webs of material there are certain objections to the method. These objections are most noticeable when an effort is made to employ the method in connection with the printing of relatively narrow webs and in particular tubes of the socalled viscose type adapted for the holding of sausage.
Another popular method of printing cellulose sheeting such as the product known as "Cellophane consists'in depositing a relatively slow drying ink on a web of the material, cutting the web into individual sheets, and stacking the sheets in superimposed relation with a slip sheet between adjacent printed sheets.
In accordance with my invention the material 10 is printed with a relatively slow drying ink, as by a later press-printing machine provided with oil inks, and a freshly printed web is rewound with a second or supporting web having marginal projections adapted to space the convolutions of the rolled part and to form a drying channel therebetween.
As shown in Fig. l, the drying device may be constructed of a web In, which may be composed of paper or similar material, and is of sufiicient rigidity as not to wrinkle or break down when rolled with the printed cellulose sheeting. Along the marginal edges of the web [0 are secured flexible cords II. To secure the cords to the backing member II] it is possible to employ a flexible adhesive tape l2 which is fixed longitudinally along the edge of the web l0 and about the cords as shown in Figs. 1 and 3. Other satisfactory ways of attaching the cords to the relatively rigid web It] may be employed. For example, the cords may be wrapped with a smaller thread which is secured through the web. Brads or staples also may be employed. I
In Fig. 5 is shown a reel member [3 which may be employed for winding the member I0 into rolled formation. This reel is of particular utility where the roll becomes of substantial diameter and tends to be distorted from its regular shape, the reel maintaining the edges of the roll in substantially vertical position. Shaft l4 on the reel is provided with openings l5 through which a drying gas may be blown, the gas being supplied through a suitable conduit IS.
The cellulose web I9 is printed, as indicated in Fig. 6 by being passed between a suitable printing roll I! and tympan cylinder Hi, the printing cylinder depositing a relatively slow drying color such as an oil ink on the upper or face portion of the cellulose sheeting 19. The printed web of cellulose sheeting is formed into a roll with the device shown in Fig. 1 in such a manner that the unprinted or back portion of the cellulose sheeting is wound, preferably under a slight tension, against the relatively rigid web I0, the printed face of the cellulose sheeting extending 5 into the space between the raised projections II and being spaced from the adjacent surface of the next convolution of the roll.
When the printed cellulose sheeting I9 is wound with the web III in the position shown in Fig. 1, that is, from the front side of the web ID,
the latter is wound with the raised projections II on the outside of the roll, as shown in Fig. 4. In this manner, the portions of the cord or proiections l I adjacent each portion of the cellulose sheeting forms the drying channel and spacing member therethrough, it being understood that in the next convolution of the roll the back portion of the web I II will rest against the top edges 01' the strings II to complete the formation of the drying channel.
As shown in Figs. 2 and 6, the freshly printed web may be rolled with its back portion against the back portion of the web lo, the web l0 being one convolution ahead of the cellulose web l9,
and the projections ll of one convolution forming the spacing elements for the cellulose sheeting which is wound in contact with the back of the next inner convolution of the web lill, as clearly appears in Fig. 6.
In either method of forming the roll a printed portion of the cellulose sheeting extends into a continuous drying space and the web I0 is of sufficient rigidity as to maintain the drying space and to prevent such a breakdown as would permit the web It to contact the freshly printed portion of the cellulose sheeting. After the cellulose sheeting has dried the roll may be unwound and the cellulose web and-the drying web may be separately re-rolled to complete the process.
To facilitate the drying operation it is possible to direct a stream of air through the continuous drying channel formed by the roll as indicated by the direction of the arrows in Figs. 2 and 4. For this purpose the reel shown in Fig. 51s of particular advantage. The stream of drying gas also may be directed from the outer opening of the roll teward the inner opening.
After the printed cellulose sheeting has dried, the combined roll ofthe channel forming web and the cellulose sheeting is unwound and the two webs separated, the channel forming web being rewound for further use.
when in rolled form with the printed web of material, the channel forming web providesan air space adjacent the printed surface and acts in the manner of a spiral rack in which the cellulose sheeting is wound.
In one embodiment of the invention I have em ployed ordinary press board as the material from which to construct the relatively rigid web. Cotton cord of approximately one-quarter inch diameter may be used as the marginal spacing members, and a flexible adhesive tape such as masking tape may be employed as the means for securing the cord to the marginal edges of the relatively rigid web. Obviously, other materials may be substituted for those named. An advantage in the use of press board as the'web of relatively rigid material is that it will resist buckling whenthe cellulose web is wound tightly with it.
Various changes and modifications of the processand device described herein may be made without departing from the scope of the invention, and all such changes are intended to be included in the appended claims.
