17 Claims.

This invention relates to a method of and to apparatus for making color cards of the kind having color chips mounted thereon and usually bearing indicia for identifying the color of each chip with a particular paint, pigment or'the like. The invention relates particularly to separating color chips from strip stock and to affixing the chips to color cardblanks. It is contemplated that suitable adhesive may be carried either on the color card blank or on the color strip for securing the chips to the blank; and also that feeding means of any aproved type may be provided for advancing the stock as new chips are to be formed. The purposes of the invention are to improve the art of forming color chips from stock and affixing them to color card blanks; to provide for holding the chips substantially in pressure contact with a color card blank as they are separated from the stock; to provide eflicient means for rendering the adhesive effective; to provide means which may be attached to apparatus of various kinds, as for instance, to well known types of printing presses, for adapting such apparatus to the production of color cards in accordance with this invention; and also to'provide apparatus of the class described having an improved construction and relative arrangement of parts.

The features of the invention are illustrated in the accompanying drawings, wherein:

withparts omitted and broken away, and illustrating the rack for supporting the strip stock;

Fig. 12 is a plan view of a cutter plate; and

Fig. 13 is a sectional view similar to Fig. 4, but showing only the cutter plates to illustrate 5 the normal positions and the abutting relationship of the cutter plates.

The apparatus selected for illustration comprises a main frame It! in which an oscillatory shaft H and a rotary shaft I2 are mounted. A crank arm I3 is fixed to the oscillatory shaft and carries a crank pin I4. A link l6 connects this crank pin to a similar pin I! mounted on a wheel 18 which is fast on the rotary shaft. Power for operating the machine is transmitted to rotary shaft l2. One of the pressure transmitting members is in the form of a supporting plate or platen l9 which is fixed on the oscillatory shaft I l. Any suitable means (not shown) may be provided for releasably retaining a color card blank in posi- L tion on this platen, as is well understood in the art. This platen carries a projectionil which is engageable with a projection 22 of a self-closing valve 23 in a supply pipe 24 which leads to a spray nozzle 26 disposed above the platen as viewed in Fig. 1. The valve 23 and the pipe 24 maybe supported by any suitable means, as by a bracket 21 mounted on the main frame.

The color chips 30 (Fig. 8) maybe formed from narrow strips or ribbons of stock (Fig. 10) comprising paper or other suitable material 28, having on one side a layer or coating 29 of paint of the color and quality desired. Conveniently the other side of the stock may have a coating 3! of adhesive. This stock may be supplied from rolls 32 mounted on spindles or cores 33 which are rotatably supported in the rack 34 mounted on the main frame. The number of rolls of stock on each spindle and the number of spindles carrying such rolls may be determined from the number and arrangement of the color chips on the finished card. The illustrated apparatus is adapted to produce the card 35 shown in Figs. 8 and 9, and hence, there are five rolls of stock on each spindle to correspond with the five horizontal rows of color chips and four spindles to correspond with the four vertical rows of chips as viewed in Fig. 8. The rolls of stock are spaced along each spindle in vertical alignment with the rolls on the other spindles (Fig. 11).

An idler roll 36 is rotatably mounted at the top of the main frame and the strip stock is passed over this roller with the strips from the vertically aligned rolls in superposed relationship. Hence, from each group of vertically aligned rolls there are four plies of stock, each from a different roll and therefore of a different color, which pass over the idler roller and downwardly between pairs of aligned feed rolls 3'? and 38 (Fig. 4). These feed rolls are mounted on shafts 39 and M supported in bearing brackets 42 and 43. A spur gear 44 fixed on the shaft 39 meshes with a similar gear 46 which is fast on the shaft 45, thereby causing these shafts and the feed rolls to operate in unison.

The feed rolls may be caused to advance the stock intermittently by any suitable mechanism as, for example, by means of a ratchet wheel 47 fixed on shaft 4! (Figs. 1 and 2) and a spring pressed feed pawl 48 carried by an oscillatory arm 49 having a longitudinal slot in which a link 52 may be adjustably connected to vary the feeding stroke as is well understood. The other end of this link may be connected to the platen IS. A spring pressed pawl 53 may also be provided to prevent retrograde movement of the ratchet wheel while the feed pawl is being retracted preparatory to engaging a ratchet tooth for a feeding stroke.

A vertically disposed plate 56 (Fig. 1) is provided with guide channels 5? (Fig. 5) for receiving the stock from the feed rolls and conducting it to points along these channels at which the color chips are formed.

Cutter plates

59, 6!, 62 and 63 (Fig. 3) are disposed across this plate. Preferably each of these cutter plates is made of resilient material such as spring steel, and is provided with

end portions

64 and 66 disposed in the same plane and adapted to be clamped against the plate 56 as by means of angle strips 67 and 63 (Fig. 3) secured along the edges of plate 56 and overlying the

end portions

64 and 66 of the respective cutter plates. Adjacent its end portions, each cutter plate is cut away to form an intermediate portion 69 (Fig. 12) which is bent outwardly from the end portions so that these intermediate portions normally assume inclined positions substantially as shown in Figs. 4 and 13. H of the intermediate portion is bevelled substantially as shown, and the edge H and the opposite edge 72 of the plate are squared so that the edge ll of one plate may cooperate with the edge 12 of an adjacent plate to sever strip stock dis-posed therebetween. The

end portions

66 and 66 of

cutter plates

59, 5S and 62 abut against the adjacent portions of the edges E2 of plates 6|, 62 and 63, while the end portions of plate 63 abut against the squared edge of a flat plate 73 affixed to the plate 56 and having a squared edge 72 which cooperates with the cutting edge H of cutter plate 63. Above the plate 56, retaining strips l4, 176, ll, l8, l9 and 8| may be arranged to overlie the edges of the guide channels to keep the stock therein. Adjacent each cf the cutting edges l2 and 72 a yieldable support for the stock is provided by elastic rubber elements such as the tubes 62 Which extend entirely across the plate 56 above the guide channels and have their ends secured as by means of cement 83, 84 (Fig. 6) to the angle strips 6? and 68 carried by plate 56.

Preferably the plate 56 and parts associated therewith are formed as a unit for attachment to existing machines, such as printing presses or other apparatus having pressure transmitting members or surfaces movable relatively toward and from each other. Thus the idler roll 36 preferably is carried by

arms

86, 81 formed as a part of the bearing brackets 32 and 43 (Figs. 3,

Preferably the underside of the edge 4 and 5) which are attached to plate 56 by bolts 88. The plate 56 may be mounted on the main frame in any approved manner (not shown).

In the operation of this apparatus the strips of color stock are taken from the underside of the supply rolls so that the tendency of the advancing ends of the strips will be to curl outwardly over the rubber tubes 82 when given an opportunity to do so. In arranging the stock for the first operation, the undermost ply in each guide channel is advanced so that its leading edge projects sufiiciently across the cutting edge "12' of plate E3 to form a chip of the desired size. Similarly the adjacent ply is brought across the edge T2 of plate 63, the next ply is brought across the edge 72 of plate 62, and the outer ply is advanced across the edge 52 of plate 6|. The color steel; is also arranged so that its adhesive bearing sides are disposed outwardly from the guide channels. A color card blank is positioned on the platen l9 and the solvent for the adhesive of the color strips may be applied over the blank as a fine mist delivered from the spray nozzle 26. It will be understood that only enough of the solvent is applied to render the adhesive fully effective.

The apparatus may then be set in operation by applying power to rotate shaft I2 which, through its connections with shaft ll, causes the latter to oscillate through ninety degrees and the platen is is, therefore, oscillated through this same amplitude. As the platen moves from the position shown in Fig. l to that shown in Fig. 2, the outwardly curling ends of the strips of color stock engage the approaching color card blank and are pressed down against the cutter plates so as to be held in position on the color card blank during the final period of clockwise motion of the platen l 9 which presses the intermediate portions 69 of the cutter plates into a substantially continuous surface in a common plane, thereby causing the cutting edges 'H to sever the projecting ends of the color strips across the cutting edges 72 and 72. It will be observed that the chips are severed from the strip stock and afiixed to the color card blank to complete the card during this instant of engagement and pressure contact. It will be evident that this operation may be carried on with great rapidity. Where higher speeds are desired, cam or other mechanism adapted to provide the requisite dwells in the motion of the platen, may be substituted for that shown.

As the platen moves in a counter-clockwise direction an attendant may remove the finished color card and place another color card blank in position on the platen. As the platen returns to the position shown in Fig. l with a new blank in position, the projection 25 engages the projection 22 and opens the valve 23 to cause the proper amount of solvent to be discharged from the spray nozzle 26, and the operations just described are repeated. It will be evident that, if desired, the nozzle 26 may be directed toward the adhesive bearing ends of the color strips instead of at the blank as shown. Moreover, thermoplastic adhesive may be used and rendered eifective by heating elements carried by the platen or by the plate 56, or an open flame may be applied directly to the color card blank or to the ends of the strips of color stock. Therefore, the term activating agent as used in the claims is intended to cover the application of heat where thermoplastic adhesive is used, as well as the application of a solvent for other adhesives. In

any case, the adhesive may be carried either by the color strips or by the color card blank.
