Machines of this-type are very large'and expensive but are'eflective for pro-' ducing large quantities of'material at high speed, However, the range: of patterns which can be produced thereby is relatively limited. By my invention thenumber' of patterns which can be manufactured is ma terially enlarged and highly desirable effects are obtainable. Q r 1 The rotary machine new in 'u'sefemploys die rolls having a circumference 'of 54' inches. The pattern repeats three times around this die roll as it is necessary to employ pin rolls for ejecting the scrap materialand for 'ap plying the remainderfto the backing, and these pin rolls must lie withinfmove' in synchronisml with the die rolls, The pat tern is repeated three time's' around the'die' rolls in present machines in-order-thatthe small pin rolls 'Inay actuate the stri'ppers employed. f H

I. e t d ha i is Qnly nec s a y t actuateja stripper under a portion of. a piece of linoleum on thejsurface 'of-adie roll, and that if proper precautions are'taken, apiece materially larger than the. stripperYm-ay be ejected. I am therefore able to actuate strippers spaced arounda die roll-with asingle actuating pin on the pin roll, but to vary the pattern by having these-stripperszeject portions of-diiferent' size or shape. There is thus obtainable a pattern having a repeat length up to the circumference.ofthe die roll; and where pattern elements having such repeat length are applied to the backing", to

gether withother pattern elements (applied by other die rolls) having the normal repeat rotary "machine 1929, Serial No 365, 25.

Humphreys, described and claimed in his 55 application, Serial No.- 363,581, filed May 16, 1929. In that application'there is described a method of making linoleum or the like by applying pattern elements by the die rolls to a portion onlyof the backing,other portions of the backing being covered by pattern elements which are applied by hand. i

This is particularly desirable for the application of haphazard spots of color which V contrast with the general background of I the design, and by my invention spaces in which the haphazard spots are applied may be left as much as 54 inches apart. In the accompanying drawings illustratingthe present preferred embodiment of my invention as applied to'the production of a tile pattern, V

The machine illustrated in Figure lc om- I prises a drum 2 having die rolls 3 spaced therearound. 1 Each die roll is supplied with webs 4 of linoleum mix from calenders 5 havi doctor bl The calendered mate'- rial is carried to the die rolls on belts 6Q Platen rolls 7 cooperate. with each die roll. As is well known, each die roll has cutting;

knives on itsfsurface, these'knives being arranged to cut into the web of linoleum miX' and divide it into pattern elements and scrap. I

I Pin rolls 8 lie within thedie rolls 3 and rotatetherewith, the pins being e fective for actuating strippers, hereinafter described, which discharge the scrap'material into con.- veyor troughs 9. Upon continued rotation of the die rolls, those portions which are not Y discharged as scrap are applied to a web 10 of backing material. p -0 Thereis a separate die roll for each color employed in thegeneral body of the pattern, and after theseveral colors have beenapplied by the machine the material travels over an inspection table 11 to a calender indicated generally by the reference character 12. After being calen'dered,

the material is carried to the-ste've' for curing. One of the die rolls 3 is shown in detailin Fi ure 2. It comprises a'shell 13*having Babbitt blocks 14 overthe surface thereof,v

these blocks engaging'knives l5'placed therebetween, Eachlzmve-bounded area is pro} vided with a stripper 16 having a pin: 1-?

The cutting is completed by a stiff brush 7a which engages the-'faceof t'he mate rial andvpushes it down into the'spaces be- Ilh'ave illustrated inFigureS a stripper ltia whose head'has a lengthL, measuring longis tudinally of the die roll; The head of the stripper 16a lies within a knife bounded area of length L. The stripper '16s is-ar ranged to be actuatedby a pin 8aon'the scrap 'rol l*8 and' this same pin 8;: also actuates: strippers 16a and lhaf. The knife-boundthe scrap ofthe linoleum pieces as ed areas for the strippers 16a and 16a? are of length L, there being a knife inserted between the blocks 14 in slots corresponding to the slot 20 in Figure 3. In the case of'the strippers 16a, however, such knife is omitted, as shown in Figure 3.

When the strippers 16a and 16a are ac-- tuated they eject pieces of linoleumof length whereas the stripper 16a ejects a piece of linoleum of length L,

the piece being forcedout from between the rolls by the Stripper as indicatedat 21 and the edge thereof being engaged by the brush 19. V Adjacent each of the strippers 16a 'and lea'f' is another stripper oecupyingthe p0 Siam correspondingato that shown at 166 in Figure It is not essential that a stripper 166 be provided adjacent the stripper 16a since if one is present it is notiactive.

L f(comesponding., to the" width of"- the areaX plusitzhe' width of? the aresSythe elements by the die roll. i The portions D1 and D2 are each illus-' trated as being 5&- inches long-the circumference of each die roll these lengths being subdivided into three portions of length (Z1 and (Z2, each 18 inches long. It will be noted from the portion D1 that the pattern elements applied by the first die roll repeat in each distance all, that is to say, they have the normal repeat length of 18 inches. This is also true in the portion D2, except that D2 differs from the other sections in the omission of the square S. Therefore, while the second die roll applies a pattern which in most particulars repeats itself every 18 inches, such pattern, considered as a whole, repeats itself only every 54 inches. With the exception of the area S, the uncovered portions of the backing are the same in each of the portions 612.

The third die roll is effective for filling in the remainder of the general body of the pattern. The pattern applied by the third die roll is shown at D3 and it will be seen that in this particular case none of the backing eX- cept at the square S is left exposed. It will be understood, of course, that my invention may be applied in those cases where the pattern elements are spaced apart so as to pro-.

duce embossed effects. 7

After the material leaves the third die roll no more pattern elements are applied by the machine and the portion D3 of Figure 5 represents the appearance of the goods as they travel over the inspection table 11. During this travel a brightly colored block is filled in These by hand in the area S indicated at 22. color blocks are spaced 54 inches apart and different colors may be used so as to give still further variety to the pattern.

I have illustrated in Figure 4 a modification wherein a stripper 23, having a width W as measured around the circumference of the die roll, is effective for stripping a section of width W as measured around the die roll, there being a knife omitted at 24 so that the stripper 23 engages a piece of linoleum materiallylarger than the stripper head. Where this arrangement is used the squares corresponding to the squares X of Figure 5' W111 lie in the same line as the squares corresponding to the squares S thereof, instead of sidewise thereof.

I have illustrated and described the present preferred embodiment of my invention and a modification thereof. It will be understood, however, that it is not limited to the form shown but may be otherwise embodied and practiced within the scope of the follow ing claims.
