Abstract
A method is described for the continuous manufacture of inlaid vinyl sheeting using different colored plastisols and rotary screen printing equipment. The printing equipment comprises an unwind stand, an accumulator, a plurality of printing stations, a coating station, an oven, a second accumulator, and a wind up stand. Optionally an embossing station may also be used. Each printing station comprises (i) a rotary screen through which a different colored plastisol is squeezed to form a colored pattern on a base layer and (ii) a hot air dryer for partially drying the plastisol deposited on the base layer. In accordance with the invention, the viscosity of the plastisol and the rate of drying is such that plugs of plastisol are deposited on the base layer by each screen to form discrete portions of the total pattern created. Several different rotary screens are used to deposit these plugs of colored plastisols on the base layer so as to build up a pattern from the different colored plastisols. Advantageously, a wear coat is deposited on top of the layer of differently colored plastisols so that the final product consists of three layers: a backing, a decorative layer of differently colored plugs of plastisol, and a wear coat.
