Definitions

  • This invention relates to the manufacture of composition floor coverings and the like, and more particularly to linoleum or similar material.
  • the invention relates specifically to what is known as molded inlaid linoleum.
  • a strip of burlap or other flexible backing supported on a conveyor is inter mittently'advanced beneath a series of stencils.
  • Each stencil has a portion of the pattern to be formed out in the bottom thereof and'the linoleum mix is sifted through the stencils onto the burlap backing. After the burlap emerges from under the last stencil,
  • the linoleum mix is passed between calender rolls to form sheets which are then cut up 7 into pieces and laid and cemented on to the burlap backing.
  • sheets of plain color are first formed and then two of these plain colored sheets are simultaneously passed through the calender rolls forcing the two sheets together and producing the blended or marbleized effect. "These resulting sheetshaving a mar.- bleized pattern arethen cut out and applied to the backing.
  • the mix is formed into wadsor balls. Balls of two colors are simultaneously'passed between the calender rolls, resulting in the formation of a sheet having the streaked or jaspe effect.
  • invention provides a linoleum of the molded inlaid type wherein marbleized or jaspe effects are obtained.
  • the invention may be understood by reference to the accompanying drawing, in which Figure 1 represents a plan view of apiece of-linoleumformed in accordance with my .
  • Figure 2 represents asection on a larger scale through a portion of the piece of linoleum shown in Figure 1 ,this View being in the plane of line JIIII of - Figure11; and
  • Figure 3 is a'somewhat exaggeratedview showing the manner in which sheeted molded inlaid-composition is applied to produce the material shown in Figures 1 and 2.
  • 2 designates generally a piece of molded inlaid linoleum which is carried on a'b'urlap or other base 3.
  • the piece of linoleum shown has a plurality of ordinary tiles 4 and 5 of the style ordinarilyformed of molded inlaid material. These tiles may be of different colors,as indicated by the cross-hatching on the drawing, and are connected a molded inlaid interliner 6, which is preferably deaccordance with the invention disclosed in" the patent of Humphreys and McCarthy, No. 1,630,085, dated May 24, 1927.
  • At? is a tile having the marbleized effect therein and at 8 is another tile having a jasp effect.
  • the molded inlaid mix is not so plastic as the usual straight line mix. It is purposely made less heat-sensitive so that it can be brushed through the stencils without sticking; Straight line mix is 'much more sensitive to heat in order that it may become plastic during the relatively short period that it contacts 'withthe calender rolls. If the.
  • the formed sheets which I employ in my process be made of a linoleuinimix having a relatively low heat sensitivity. instead of a straight line mix, such as has heretofore been employed for sheeting. This low heat sensitive mix, in-
  • the sheeted material is of less thickness than the granular material which is placed. over the backing butafter the entire body of gioodshas' been subjected to'its final compress1on, as shown 1n F1gure2, the granular material and the preliminarily sheeted material less than if the portions 7 and 8 were initially are both reduced to the same thickness. 7
  • the sheeted material formed from the molded inlaid mix in accordance with the present invention is not very strong structurally merely having sufficient body to enable its being handled as required, the purpose of sheeting being merely to obtain the desired design effect.
  • the marble or j asp or other irregular effect is produced with molded mix in the same way that similar effects are producedin the sheets'used for straight line inlays. After the partially compressed sheets of marble or jasp have been to'rmed,-they are-cut into pieces of thedesired. size and shape.” At one or more stations along the molded inlay machine in which the'linoleum shown in Figure 1 is produced, these pieces may be dropped through the stencils in place of sitting the usual granular mix therethrough, or they are dropped into spaces left toreceive them after the backing, with the moldedgranular mix haspassed under all the-stencils.
  • the sheeted inlays 7 and 8 are of the same composition as the titles-4 and 5 and the interliner 6, the sheetedmaterials 7 and 8 will unite with the ad-- j acent material and become an integral part thereof. Also by reason of the fact that" the Y material of the inlays 7 and 8 is only partially compacted before it is subjectedto the final pressing, it will become more firmly bonded to the adjacent material. Furthermore, since the sheeted inlays-7 and 8 are only partially compacted, the difi'erence in the thickness of the inlays '7 and 8 and. the loose materialis compressed to the final thickness. Because ofthere being less difierencein thickness;
  • j asp or marbleizedefiiects orboth can be secured in molded inlaid linoleum, andthis has" not previously been possible.
  • the j asp and marbleized-tiles can be spotted in with apparent irregularity to relieve the monotony of the solid color tiles and give a novel-and pleasing appearance to the finished product.
  • the sheeted material be-v 7 comes an integral part of the molded inlaid material. There is no joint which can bede teeted, the sheeted inlay becoming an integral part of the goods.
  • the composition and density of the sheeted inlays in the finished pattern can be the same or substantially thesame as the density of the 'molded'portions otthe binder or any specific filler.
  • the invention is particularly adapted for the production of jasp and marbleized effects in a molded inlaid material, it is not limited to the production of such effects. It can also be advantageously used in making inlays of solid color and in a variety of colors where ordinary processes alone would not permit of the variety of color or the haphazard arrangement which can be secured by using sheeted inlays in combination with molded inlays.
  • the molded inlaid linoleum is subjected to greater pressure at the points of juncture of the two materials than is the major portion of the sheet whereby it is assured that the molded material will more securely unite with the sheeted material.
  • the edges of the pieces of sheeted material may also be depressed to more firmly bond such pieces in place.
  • V a i j The method of making an inlaid linoleum-which comprises forming loose linoleum mix into pieces of partially compacted sheets ed linoleum, applying such piecesto asupporting backing, applying loose linoleum mix to the backing adjacent the pieces of sheeted linoleum and thereafter compressing: the 1 whole to compact the loose material and further compact the sheeted material and form a substantially integral piece of linoleum.
  • Theinethod ofmakingan inlaid'lino- I leum which comprises forming loose linoleum mix into pieces of partially compacted sheeted linoleum, applying such pieces to a supporting backing, applyingv loose linoleum mix to the backing adjacent, the pieces of sheeted I extent thanthe remaining area of the piece to more firmly unite the whole.
  • steps consisting in applying granular mix to a portion only of a backing, filling in the pattern with preformed pieces of linoleum of less thickness than the applied granular material, and compressing the material to consolidate the mixes.
