44 Claims.

This invention relates to the printing art and is herein particularly described as applied to the manufacture of printed surface coverings of the felt base type. It is herein specifically described as applied to the manufacture of surface coverings having portions only of their area covered by a printed pattern simulating the appearance of natural marble. The other portions of the area of the surface covering are decorated with any suitable pattern adapted to harmonize with the marbleized areas.

Printed surface coverings simulating natural marble in appearance have been known for some time as disclosed in my prior United States Patent No. 1,773,063. Such coverings have been formed by passing a. web of felt base or similar material under some suitable color applying means which deposited the paint in worm-like applications upon a base coat. The web traveled from said color applying means to a mash block which served to fuse the worm-like applications` ,into the base coat. The resulting marble imitation wasnecessarily very crude, devoid of ne graining effects, and characterized by mechanical repeats.

In some cases designs have been printed over portions of marbleized patterns to break the continuity of the marble pattern and to obtain distinctive and novel decorative effects. 'I'he eects obtained by said process have proved to be exceptionally attractive, but the process is inherently bad because it is wasteful and extravagant. A pattern simulating natural marble involves the intimate mixture of a plurality of colors. It is impossible to print a marble pattern with a print block. Accordingly it has heretofore been considered impossible to coat a felt base with a marbleized design extending over only those portions which are to appear as simulations of natural marble in the final product. The portions of the coating of paint simulating the appearance of natural marble which are later covered by a different design serve no useful purpose.

Another serious disadvantage of patterns of surface coverings attempting to simulate the appearance of natural marbles heretofore has been the presence of brush marks visible in the completed patterns. The surface covering material must be fed through the printing machine with an intermittent motion to permit printing of various designs thereon by the conventional printing blocks. The portion of the surface covering material under the paint spreading means, at the time the feeding movement of the surface covering material is halted, receives a distinctive v to provide means for synchronizing the various paint applying means in my coatingapparatus so that designs other than those simulating the appearance of natural marbles may be interposed between the areas covered by the marblelzed designs to complete the decorative coating on the surface covering. It is a further object of my invention to provide means for causing a uniform relative motion between an intermittently moving web of surface covering material and a continuously reciprocating paint spreading mechanism. It is a. further object of my invention to provide a coating apparatus that will eliminate brush marks which have heretofore been incident to the striating of printed patterns. Itis a. further object of my invention to provide a coating apparatus that may be readily applied to and removed from a conventional printing machine as a unit with a minimum expenditure of labor.

By my invention it is possible at a low cost to obtain a surface covering which has the highly desirable qualities from the standpoint of appearance of natural marble, without any apparent repetitions of pattern and with a soft blending of color not heretofore obtainable in printed goods. I apply a color or colors to predetermined areas on a web of surface covering material, spread the same longitudinally and laterally of the web, and then engage the colors thus spread and further spread them. Preferably the rst spreading action is to form sinuous streaks of color. I prefer to perform this first spreading action by means of a soft flexible brush which is moved laterally and longitudinally over the surface of the web. The second spreading operation is accomplished by means of a thin flexible doctor blade which serves to smooth the coating as well as to impart to it the characteristic appearance of natural marble.

It is possible also to apply the marbleized pattern over only those units which are to appear as simulations of natural marble in the nal product. This effects an enormous economy in the amount of paint required to coat a given area of surface covering material. For example, if the finished pattern is to show a marbleined design over half the area and non-marbleized designs over the other half, my process will require approximately two-thirds of the amount of paint required by prior processes wherein the marbleized design was applied over the entirearea of the surface covering material and the nonmarbleizeddesigns were obtained by over printing. My' process would save one-half the paint used to form the marbleized areas of such a pattern. Since the cost of paint is a maior consideration in the production of surface coverings of the i'elt base type, it is obvious that this saving cf paint is of prime importance.

In prior art processes it has been necessary to apply a marbleized design over the entire surface area of the web of surface covering marial being decorated. The design not simulating marble was then overprinted on portions of the marbleized design. This practice results in a paint coat of non-uniform thickness, the areas not simulating marble being covered with a paint layer approximately twice the thickness of the paint coat over the marbleized areas. The lack of uniformity in the thickness of the paint coat introduces -a very serious dimculty in maturing the surface covering material. It is impossible to obtain even maturing of the paint coat without extremely accurate control oi' the drying characteristics and viscosity of the constituent paints. Such control is entirely too costly for commercial operation. If the material is stoved long enough to mature the thicker portions of paint. the thinner portions are often too brittle, and if the thinner portions are properly matured, the thicker portions are generally too soft.

Another distinctive advantage'of my invention is the elimination of the characteristic brush marks which have always been present in brushed paint patterns. It is desirable to use block printing machines; of the type now generally employed in the iioor covering industry, to apply portions of the decorative pattern to the surface covering material. However, the use of such machines introduces serious problems, particularly because it is necessary to move the surface covering material through the printing machine in an intermittent manner. y In order to obtain the best results it is important that the brush and doctor employed be maintained in relative movement with respect to the material at all times, as otherwise marks will be left on the product which will mar the beauty of the design and decrease the value of the'surface covering.

I accomplish the result desired by providing an oscillating brush and doctor which are reciprocated back and forth longitudinally of the machine and are so controlled that the change in direction of the reclprocatory movement of the brush and doctor occurs when the surface covering material itself is moving. 'I'he speed of the brush and doctor relative to the material ls not particularly important so long as there is a reasonable degree of relative movement at all times and this relative movement is substantially uniform. They brush and doctor, therefore, will be moving part of the time with the surface covering material along the bed of the machine but at a different rate. The brush and doctor will commence their return stroke just before the material being decorated comes to rest for the printing step. Immediately before the brush and doctor have completed their return movement, the material will have again commenced its forward movement. Accordingly, it will be seen that there is never any period at which there is no relative movement between the web of surface covering material being decorated and the brush or doctor.

My invention will be readily understood by reference to the following description taken in connection with the accompanying drawings illustrating the present preferred embodiment of my invention in which;

Figure 1 is a diagrammatic view illustratingthe eiiects of the various printing blocks and color spreading apparatus on a sheet oi' surface ccvering material;

Figure 2 is a perspective view of my lcolor spreading means with parts broken away to facilitate the illustration of its component parts;

Figure 3 is a plan view of my color spreading apparatus:

Figure 4 is a front elevation of my color spreading apparatus;

Figure 5 is an end elevation lcoiringy in the direction of thearrowAofFigurehand Figureiiisacrosssectionalview ontheline VI-VI of Figure 4.

Referring to Figure`1, the reference numeral 2 indicates a pin band movable over a pair of rolls I and l. A sheet l of surface covering material, such as felt base, is fed from a supply roll l to the pin band 2. The sheet 5 is fed through 30 the printing apparatus intermittently. During the periods of rest the sheet i is acted on by the printing blocks 1, l, l, I0, Il, I2, and i3. 'I'he printing blocks 1 and I apply marbleizing" col'- ors to the web of surface covering material. By the term "marbleizing colors" I mean those colors which are later brushed and smoothed to form marbleized or other striated designs. rAlthough I have shown blocks for applying these colors, any suitable means may be employed for this purpose. Other means may be employed, in conjunction with said blocks 1 and 8, to increase the number of marbleizing colors applied to the sheet i. 'I'he printing block 9 applies a base color over the colors applied by the blocks 1 and 8.

It is possible to apply the base color directly to the felt base and to apply the marbleizing colors on top of the base color. However. the application of the marbleizing colors underneath the base color is advantageous in that the marbleizing colors extend throughout the thickness oi' the paint coat. 'I'he striations extend all the way to the felt so that the surface covering material retains its striated appearance even after the top surface has been worn away.

'I'he marbleizing unit il is provided with a brush` which spreads the paint into sinuous streaks and brings the marbleizing colors applied by the printing blocks 1 and 8 to'the surface of the color applied by the color block il. Themarbleizing unit I4 is also provided with a doctor which smooths the brushed paint and imparts to the surface covering material the appearance of natural marble.

'I'he blocks ill, il, I2, and i3 are conventional 65 printing blocks. This offsetting compensates-for the drag of the brush so that the marbleized design is correctly positioned in relation to the other designs of the completed pattern. If the blocks 1, 5. and 9 applied their colors in the exact space reserved for the marbleize'd design in the c ompleted pattern, the drag of the brush would wipe substantially all the paint off small areas in front of the marbleized dign and spoil the pattern. Instead of oifsetting the blocks 1, 5. and 9, the same eifect may be obtained by oifsetting the paint applying portions oi the blocks. It will be obvious that the blocks I5, II, I2, and I3 may be oil'set to obtain the same result.

'I'he marbleizing unit I4 includes a pair of channel irons I5 which extend across the width of a conventional printing machine. 'I'he channel members I5 are connected by cross rails I5 and I1. An intermediate pair of cross rails I5 and I9 serve to support the mechanism for imparting oscillatory motion to the marbleizing elements. The cross rails I5 and i1 are provided with angle brackets by which the marbleizing unit is supported on the printing machine. The cross rails I5 and are of sufiicient length to occupy the space ordinarily taken by two adjacent printing blocks. The brackets 2|| are provided with elongated slots 2| which are adapted to fit around a lug on a conventional printingmac'hine.

The brackets 25 vare formed with a depending flange 22 provided with a screw threaded 'opening 23. When the marbleizing unit is positioned on the printing machine clamping bolts 24 extending through the openings 23 serve to lock the marbleizing unit in place. The clamp bolts 24 Vare provided with lock nuts 25. The clamp bolts 24 are adapted to adjust the longitudinal position of the marbleizing unit with respect to the printing machine within the limits permitted by the length of the slots 2|.

The channel members I5 are provided with brackets 25 which serve to support a slide rail 21. A slide 25 is mounted on the slide rail 21. The slide 25 is provided with an enlarged portion 29 which has an elongated slot therein. 'Ihe slide 25 is provided at one end with a journal 3|. The journal 3| serves to support one end of a shaft 32. Thejournal 3| is provided with an integral gear segment 33 adapted to engage with a worm 34 on the end of a shaft 35. A hand wheel 35 is secured to the upper end of the shaft 35. The hand wheel 35 may be rotated to effect angu lar adjustment of the shaft 32 the end of which is secured in the end of the journal 3|. Another shaft 31 is supported at one end in a journal 38 having an integral gear segment 39 engaging a worm on one end of the shaft 4|. The other end of the shaft 4| is provided with a hand wheel 42 so that the angular position of the shaft 31 may be adjusted in the same' manner as that of the shaft 32. The opposite ends of the shafts 32 and 31 are supported in bearings 43 secured at opposite ends of a slide 44 similar to the slide 25. The slide 44 is mounted on a slide rail 45 supported in brackets 45 secured to the channel members I5.

The shaft 32 is provided with a plurality of brackets 41 adapted to support a marbling brush 45. 'I'he back 49 of the brush is provided with an up-turned member adapted to be held by the brackets 41. The shaft 31 is provided with a. plurality of depending plates 5I to the lower end of which an angle member 52 is secured. The bottom leg of the angle 52 serves to hold a thin flexible metal doctor blade 53.

55 is mounted in bearings 5I secured to the lo cross rails I5. 'Ihe opposite'end of the shaft 55 supports the gear 59 which is in mesh withthe crank gear55 on the slide 44. One gear 59 is engaged by a gear 52 which is supported on a shaft 53 rotating in a bearing 54 mounted on the l cross rail I1. The shaft 53 extends through the bearing 54 and is provided at its outer end with a sprocket 55 which may be driven from any suitable source of power (not shown).

Rotation of the sprocket 55 turns the shaft 53 20 to which it is secured. The gear 52 is turned withv the shaft 53 and imparts rotation to the gear 59. The gears 59 are connected by the shaft 55 so that both gears are rotated simultaneously.

The gears 55 rotate the crank gears 55 and irn- 25 part reciprocatory motion to the slides 25 and 44 by means of the pins 51 which are coniined in the slots 35. Accordingly, it will be seen that the marbleizng brush 48 and the doctor 53 are reciprocated simultaneously. 33

The reciprocatory mechanism is so regulated that as the surface covering material moves through the printing machine, the brush and doctor are moved in the same direction as the surface covering material at half the speed of the 3 surface covering material. The surface covering material moves in the printing machine a distance of 18 inches and then stops automatically while the printing blocks are lowered. The

time periods of travel and rest of the surface covering material moving intermittently through the printing machine are equal. While the surface covering material is being moved a distance of 18 inches the brush and doctor are moved a distance of 9 inches in the same direction so that 45 the relative motion between the brush and doctor and the surface covering material is 9 inches. Just before the travel of the surface covering material is stopped the direction of travel of the brush and doctor is reversed and the brush and Y doctor are moved 9 inches in the opposite direction during the period the surface covering material is at rest in the printing machine so that the relative motion between the brush and doctor and the surface covering material is the same as when the surface covering material is moving. The direction of travel of the brush and doctor is again reversed immediately after the surface covering material begins to move.

The reciprocatory mechanism is so timed that m the relative movement between the brush and doctor and the intermittently moving web of surface covering material is constant and is substantially uniform at all times.

One end of the shaft 53 is mounted in the bear- C;

ing 55 which is supported on the cross rail I9. A gear 51 is keyed to the shaft 53. 'I'he gear 51 meshes with a gear 55 keyed to the sleeve 59. The sleeve 59 traverses the space between the cross rails I8 and I5 and is supported by the bear- 71 ings 10 mounted on the cross rails. The sleeve fits loosely over the shaft 55 so that the shaft 55 and the sleeve may be rotated independently. A pair of bevel gears 1I is keyed to the sleeve 59. v

A T-shaped bracket 12 is secured to the shaft 7;

oscillating motion to the `marbleiaingf brush Il.,

The doctor blade I is oscillated by similar mechanism' except that the pin 1l is closer to the centerofitsdisklisothattheoscillatingstroke of the' doctor blade is less than the 'oscillating stroke of the brush. It will be obvious that the positionofthepins llmaybevariedatwillto adjust the oscillating stroke of either the brush 'or doctor to any desired amplitude.

The pin bands 2 are providedwith a plurality of pins 1I which project through the web of surface covering material 5 to insure positive and accurate movement of the web through the printing machine. The pins 1l are necessary to insure positive feed of the surface covering material, but are objectionable under the marbleiaing unit because of interference with the oscillating stroke of the doctor blade Il. The pins are spaced together so closely that it is impossibleto synchronize the oscillatory motion of the blade so as to move-it in and out between the pins without damage to the blade or pins. I have overcome this disadvantage vin my apparatus by the provision of a metal plate t0, positioned under my marbleizing unit I4, over which the web of surface covering material must pass. 'Ihe plate lll is cut away, as indicated at 8l, to allow the pin bands 2 to pass thereunder.

The pins I9 form small projections on the upper surface of the surface of the web 5 when they project therethrough. These projections remain on the web after the web has been separated from the pin bands and are suiliciently rigid to force the doctor blade 53 out of contact with the paint film so as to render it useless. Accordingly, I have provided means for flattening the projections formed by the pins. A pair oi' arms I2 is secured to the front channel iron I5. 'I'he arms 82 support a shaft B3 to each end of which a bell crank 84 is secured. A roller I5 ismounted on the free end of one arm of the bell crank 8l. The other arm of the bell crank is provided with a counterweight I6 adapted to force the roller It against the web of surface covering material. 'I'he counterweight is secured to the bell crank Il by means of a set screw l1. The rollers 8l are positioned directly over the projections formed in the surface covering material by the pins 18 and are forced downwardly with sumcient pressure to flatten the projections, but not sufilcient to interfere with the travel of the web. The rollers are narrow enough so that they do not run over the paint applied by the blocks 1, l, and 9.

The combined oscillatory and reciprocatory movement of the brush 4B serves to bring the marbleizlng colors applied by the printing blocks l and I to the surface and to give it a sinuous, wavy eect. The constant relative motion of the brush with respect to the web D is opposite to the direction of travel of the web 5. Accordingly, the brush Il has the tendency to drag the color applied by the blocks 1, B, and t slightly to the rear of the areas to which the color has been applied. Since the relative movement between the brush and the web is substantially uniform the amount of drag is the same in all cases and may be compensated i'or` by proper adjustment of the blocks aosepvi 1, l, and l or the blocks Il, Ii, I2. and I3. The thin flexible doctor blade Il smooths the brushed colors and gives the final product an appearance closely simulating that of natural marble.

The amount of color applied by the printing 5 blocks '|,I,and0whichremalnsinthoseareasy destined for non-marbleised designs in the na'l pattern is so small as to be practically ncgliliblc. Accordingly. the unal decorative coating is of substantially uniform thickness over the entire web of surface covering material.

Itwillbe seenthatIha'veinvented a newand improved surface covering material as well as a method of and apparatus for producing the same. Although I have described my invention in considerable detail, it will be understood that various features thereof may be modified without departing from the spirit or scope of my invention. Accordingly, I do not desire to be restricted to the specific details disclosed except as limited by the 20 appended claims.
