ABSTRACT:
A process for the production of patterned tiles from thermoplastic synthetic resins includes the steps of forming a length of crude sheet stock by compressing unicolored and/or differently colored or multicolored particulate material of thermoplastic synthetic resin; cutting off crude sheets from the sheet stock; punching segments out of the crude sheets; combining the segments from at least two crude sheets of differing colors into a panel so that the segments complement one another, and thereafter press-molding the segments to form an intarsia tile with the use of pressure and heat so that the segments are welded together along joints formed therebetween.
