Abstract: 354,349. Mosaic fabrics. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A.-(Assignees of Humphreys, C. F.; Lancaster, Pennsylvania, U.S.A.) May 1, 1930, No. 13442. Convention date, May 16, 1929. [Class 140.] Relates to machines for applying pattern elements to a base web, in which the elements are cut by the rolls from a number of separate webs of facing material, and that part of each web not required for the pattern is discharged as scrap. To avoid the production of the large area of scrap corresponding with widely-spaced areas of colour in the pattern, the machine is adapted to leave such portions of the base web uncovered, and these are filled in by hand as the patterned material passes over the inspection table. To increase the repeat length of the pattern some of these areas may be of contrasting pattern whilst others are of a pattern merging with the background. The material may finally be calendered. Pattern elements may be spaced apart, as shown at 18, Fig. 3, especially in imitating tiling, the web 17 being of the colour of mortar joints and the tile 19 of coitrasting colour being laid in by hand. Pattern elements may also be laid upon some of the tiles and consolidated by calendering. The process may be cairied out in a rotary machine, Fig. 1, comprising a main drum 2, and die-rolls 3 fed with linoleum mix from calenders 5 by belts 6. The die-rolls are provided with scrap rolls 8, strippers, brushes Sa and pattern rolls (not shown). The web 10 forming the backing consists of burlap covered with a tacky linoleum mix. The material from the drum 2 passes over the inspection table 12, where the uncovered parts may be filled in, to a calender roll 21.
