Patented Sept. 15, 1936 UNITED STATES PRINTING AND EMBOSSING DIE Fred Weindel, Jr., and Wilbur F. Price, Allentown, Pa., assignors to L. F. Grammes & Sons, Inc., Allentown, Pa., a corporation of Maryland Application October 14, 1932, Serial No. 637,676

3 Claims.

This invention relates to printing and embossing dies of a kind useful more particularly in the production of multicolor cards or labels from sheet materials such as paper-backed metal foil.

Dies of the kind referred to ordinarily consists of several printing sections to take the different colors, these sections being relatively movable so that the printing or type. face of one may bebrought above or below the printing or type faces of the others to enable selective application of the colors preparatory to making each impression. For the production of two color labels, for example, the construction of the dies has been such heretofore, as to restrict placement of the different colors, with consequent limitation in the design or decorative variations which could be obtained. In other words, with the usual type of dies embodying, say a main die section, and a secondary die section movable in said main section as and for the purpose explained, it was impossible to print the color relegated to the main die section within the area printed in another color by the secondary die section, or to print the color of the secondary die section in different portions of the area printed by the primary die section without resorting to stagewise printing.

Our invention is directed toward overcoming the recited drawbacks in multicolor label printing and. to make possible the production, by single impressions, cards or labels characterized as above explained, which end we attain as fully explained in the detailed description which follows of the attached drawing, wherein Fig. I

' shows a cross sectional view through a printing and embossing die embodying our invention in one form.

Figs. II and III are fragmentary illustrations corresponding to Fig. I showing the different positions to which the secondary section of our die is moved incident to inking of the die.

Fig. IV shows a label produced with the die of Figs. I-III.

Figs. V, VI and. VII are views like Figs. I-III showing another form of our novel printing and embossing die; and

Fig. VIII shows a label produced with the die of Figs. V-VII.

Referring first more particularly to Figs. I, II and III of these illustrations, the numeral 10 designates a die block constituting a part of a printing machine, and the numeral II a surmounted printing and embossing die embodying our invention in one form for producing the twocolor label of Fig. IV. As shown, the die ll comprises an integrally formed main section l2, and a secondary section l3, which, in this instance is annular and occupies a correspondingly configured central recess M in said main section with capacity for being moved up and down therein. The outer type ridge l5 oi the main die section I2 prints the outlining figure or border A of the label of Fig. IV, and the inner ridge l6 prints the infield or center B of said label both of the same color, e. g. blue; while the type face ll of the secondary die section i3 prints an annular area C of a, contrasting coior, e. g. red, around the infield or center B. The unshaded portions D, E and F of the label show the natural color of the metal foil (e. g. brass) forming the base of the label, by virtue of the depressions l8 between the ridges l5 and i6'of the main die section l2. In order that the label may be cut from the stock foil concurrently with its printing, the main die section I2 is formed 1 with a continuous perimetric cutting edge I9.

In the use of the die of Figs. I-III, the blue ink is first applied by a roller or pad of the printing machine to the ridges l5 and N5 of the main die section l2 at a time when the annular secondary die section I3 is depressed in the recess M of said main die section as shown in Fig. II. With this accomplished, the secondary die section [3 is raised, as shown in Fig. III, so that its printing face I! is above the level of the ridges l5 and 16 of the main die section l2, and the red ink applied thereto by another of the color pads or rollers (not shown) of the printing machine. Thereupon the secondary die section I3 is lowered until its printing face I? is flush with the type ridges l5 and I6 of the main die section I2, as in Fig. I, in readiness for a printing operation. The base sheet (not shown) for the label is then finally placed on the die H and pressed into contact therewith in the usual and well known way to receive the impressions, and incidentally blanked by the severing edges I9 of the main die section l2. In the illustrated instance the secondary die section I3 is connected to the vertically reciprocating plunger 26 of the printing machine by projections inthe form of dowel pins indicated at 2| which extend through correspondingly allocated apertures in the main section I2; and the center portion of the main section I2 is supported and braced by a bridging piece 22 lying crosswise of the guide opening 23 for said plunger in the die block.

From the foregoing it will be seen that with a die constructed according to Figs. I-III, it is possible to produce, in one operation, ornamental labels or cards wherein portions of one color lie within, as well as beyond portions of another color.

In the form of our improved printing and embossing die shown in Figs. V-VIII, there are two secondary sections H311 and l3b which are movable up and down in openings Ma and Mb respectively in the main section l2a, said secondary sections being here directly secured to the plunger a of the label printing machine. The ridges I5a of the main die section [2a in this case, define, as shown in the label of Fig. VIII, an outlined arrow A with a diamond at the center of its shaft in blue; while the secondary die sections |3a and I 31) define solid red areas C and C respectively at the tail and head of the arrow. As in the first exemplification of our invention, the depressed areas of the die of Figs. V-VIII permit showing of the color of the metal foil in the areas E and F beyond and within the two-color figure produced in the label. Thus with the die construction of Figs. V-VII, the secondary color (in this instance red) can be placed at difierent points Within the area of a figure produced by the primary color (blue).

The two different dies and labels herein featured are to be considered as illustrations merely of innumerable other designs which can obviously be predetermined by variant arrangement and formation of the main and secondary die sections. The number of secondary die sec tions can of course be increased in either case in accordance with the character of the ornamentation which is to be produced in the card or label.

Having thus described our invention, we claim: 1. A die of the character described, comprising an integrally-formed main printing section with infield and outfield areas; a secondary printing section with an annular printing area for a different color continuously around the infield area of the main section and recessed into the latter with capacity for being moved in and out of the same to enable separate inking of the two sections; and an actuating member with projections extending through the back of the main section and connecting with the secondary section.

2. A die of the character described comprising an integrally formed main printing section with infield and outfield printing areas; a secondary printing section with an annular printing area for a different color continuously around the infield area of the main section and recessed into the latter with capacity for being moved into and out of the same to enable separate inking of the two sections; and an actuating member connected to the secondary section by a number of pins extending through guide apertures in the back of the main section.

3. A die of the character described comprising an integrally formed main section with raised areas to emboss and print outfield and infield areas; a secondary section with an annular printing area for a different color continuously around the infield area of the main section and recessed into the latter with capacity for being moved into and out of the same to enable separate inking of the two sections; and an actuating member with projections extending through the back of the main section and connecting with the secondary section.
