An improved process, particularly adapted for making that type of sheet vinyl covering materials known as inlaids by first depositing resinous particles on a wet ungelled layer of PVC plastisol or organosol and then passing the sheet between a heated, cylindrical surface and a means for gradually and uniformly increasing the contact pressure between the cylindrical surface and the coated surface of the sheet. Upon completion of the step, a substantially uniformly, gelled matrix layer is produced, with the resinous particles embedded therein, and having a smooth and firm surface of uniform thickness. |
