This invention relates to the combination of a label and a molding and printing plate for forming the label. This invention also relates to the label andthe method of making the same.

Rubber labels having gures imprinted on the face of the label in the color of the background have been made by molding a sheet of rubber with an imprinted molding plate. In accordance with such practice the figures may be imprinted in relief or in intaglio which gives them depth, but the gures so formed in the color of the background are not clearly outlined and are not very attractive.

Multi-colored labels having figures of a predetermined color formed on a background of a different color have been made by printing the figures on the plane surface of a backing-up sheet which forms the background of the label. 'I'he material .deposited as an ink upon'the backing-up sheet in that type of label is relatively thin as compared to the thickness of the backing-up sheet and it is slightlyraised above the surface of the sheet. structurally this is not desirable because the thin deposit is subject to as great or greater wear than the thicker backingup sheet. Furthermore the figures are not raised sumciently to give them the desired depth as may be obtained when they are formed by imprinting them either in relief or in intaglio. g v

In accordance with the present invention the desirable features of both types of labels are obtained and the undesirable features are eliminated by producing imprinted figures upon the face of a rubber composition label in which the raised or elevated portions of the face are formed of the same material as the backing-up material and the depressed portions are formed of a relal tively thin flexible material having a color which contrasts with that of the raised portions of the face and of the backing-up material. The label is made by imprinting figures upon the surface of a plate and` coating the elevated surface portion with a relatively thin flexible adhesive material such as rubber ink. "Ihe backing-up material, comprising soft vulcanlzable rubber composition, and the treated face of the plate are f pressed together. to force the soft rubber of the backing-up material into the depressions of the plate and to cause the other portions of the backing-up material to adhere to the thin coating of adhesive material applied to the elevated surfaces of the plate. l

The impression thus produced to form the label may be made directly upon the surface of the rubber article before it is vulcanized. The

article with the plate impressed thereon is then vulcanized. In this case the rubber material of the article forms the backing-up material.

The impression may also be made on a soft vulcanizable sheet of rubber composition separate from the article. The label so made and while applied to the plate may be partially vulcanized or completely vulcanized. Where the label is partially vulcanized it may be vulcanized to the article while the article itself is being vulcanized. In this case the label is vulcanized to the article while the plate is applied thereto so that the elevated surfaces of the label will not be deformed by the vulcanizing press or mold. When the label iscompletely vulcanized it may be stripped from the backing-up sheet and subsequently cemented to the article.

The elevated portions of the face of the label i embodyingl this invention are composed of the same material as the backing-up sheet or the backing-up material of the rubber article on which the imprint may be made. As such elevated portions are relatively thick and stand out above the relatively thin material of a different color which may form the background of the label, the thin material `is protected and the contrasting color effect will be maintained usually until the face of the label has been worn to or below the'thin material. v An embodiment of the invention and the'method of making same is described in reference to the accompanying 'drawing in which: Fig. 1 is the back view of the label secured to the printing and molding plate;

, Fig. 2 is an enlarged section on line 2 2 of Fig. 1;

Fig. 3 is a partial view of the molding and printing plate face showing the label partly removed therefrom; Y

Fig. 4 is a plan view of the plate having a label applied thereto and vulcanized to a rubber article;

Fig. 5 is an enlarged cross-section of Fig. 4 taken on line 5 5.

Fig. 6 is a partial section of a label having the backing-up material deposited on fabric.

As illustrated in the drawing, the label I0 is provided with an imprinted face Il on which the figures I8 are impressed or formed in relief, but they may be formed in intaglio. The label I0 comprises a layer of relatively thick rubber composition backing-up material I4 having projecting surface portions I5 `which form the relief portion or elevated portion of the figures. The depressed surface portion i6 of the face of the label I Il4 iscovered with relatively thin flexible material I1 which is made of a different color from and is united to the backing-up material I4. Ihe face of the label is imprinted by a plate I8 having a molding and printing face I9 which conforms to the shape or contour of the face of the label III. The label I may be applied to a rubber article while it is assembled on the plate I8 as shown in Figs. 4 and 5, or the label I0 may be removed from the plate I8 in the manner illustrated in Fig. 3 and then applied to the rubber article.

The label may be made by forming an imprint upon the face I9 of the plate I8. In accordance with such method the plate I8 is preferably made of relatively thin aluminum sheet material and the figures are pressed into the face of the plate. As illustrated herein, the gures formed in the printing plate are imprinted in intaglio, but the figures may also be imprinted in relief so that the figures formed thereby on the label may come out in intaglio. The elevated surface 20 only of the face of the printing plate is coated with relatively thin coating material I1. The coating is made of such a consistency that it will not flow into the depressions 2I in the face I9 of the plate. Preferably the coating is made of a rubber ink of any desired color which may be made by thoroughly breaking down rubber and then dissolving it in a suitable solvent, and coloring with the desired pigment or the ink may be made from suitably compounded and colored rubber latex. A rubber ink of the proper consistency may be applied by inking rollers of any suitable type, either hand or machine operated. In order to insure that the elevated surface 20. of the printing plate is completely covered, the plates are preferably given two passes with the inking rollers and the second pass is made before the first coating has dried. The ink is then dried.

'I'he label I0 may be form'ed by super-imposing the inked face I9 of the plate I8 upon the soft unvulcanized surface of a rubber composition article or upon the soft unvulcanized surface of a rubber composition backing-up sheet separate from the article. In either case the material of the article or the backing-up sheet will provide the backing-up material I4 which contrasts in color with the ink I'I. The plate I8 and the backing-up material I4 thus assembled are placed in a vulcanizing press orrmold. The face I9 of the plate is pressed against the material I4 with sufficient pressure to force the material into the depressions 2| of the molding and printing plate I8 to form the elevated portions I5 upon the label I0 and cause the ink coating I'I to adhere to the backing-up material I4. The degree to which the vulcanization of the rubber composition I4 is carried depends upon how the label is applied to the article.

If the label I0 is formed by applying the plate I8 directly to the surface rof the article to be labeled, the plate can be placed in the mold in which the article is vulcanized. In this case the label Ill is vulcanized in the surface of the article while the article is being vulcanized. After the article is vulcanized and removed from the mold, the plate I8 is removed from the article and the ink I1 sticks to the depressed surface portions of the label I0.

In the event the label I0 is formed by applying the inked face I9 of the plate I8 to a backing-up vulcanized in the vulcanizing press. Before the sheet material I4 and the plate I8 applied thereto is placed in the press. the exposed back vsurface of the sheet is dusted with talc and placed upon fabric to prevent the labels from stickingtogether or to the press. After the labels have been vulcanized to the desired degree the plate I8 with the label Il! adhering theretois removed from the press. 'I'he backing-up sheet material I4 is trimmed around the edges of the plate I8 and the talc is removed from the sheet.

In the event it is desired to vulcanize the -label formed on a backing-up sheet to an unvulcanized rubber composition article, the sheet is partially vulcanized and applied to the article with the plate attached thereto as shown in Figs. 4 and 5. In this operation the back of the partially vulcanized label is placed upon the unvulcanized article 22 and the two arev vulcanized together which may be done in a vulcanizing press or mold. The plate prevents the label from being deformed by the pressure of the press and is removed from the label after it has beenvulcanized to the article.

In case the label is cemented to the article it is preferably completely vulcanized and is stripped from the molding plate I8 as shown in Fig. 2 and is applied to the article by applying cement to the back of the label and adhering it to the-article which may already be vulcanized. To prevent the label from stretching the backingup layer of rubber composition I4 may be deposlted upon a fabric sheet 23 as shown in Fig. 6, all other operations being carried out as hereinbefore described.

While certain forms of this invention have been described, it will be understood that changes in details shown and described may be made without departingl from the spirit of the invention and the scope of the appended claims.
