Abstract: This process of forming ornamental joints comprises sticking a sheet flooring material onto a floor base, thereafter drawing two parallel standard lines on this stuck sheet flooring material with a desired outline and an interval corresponding to the width of the joint, sliding a cutter on the sheet flooring material along this standard line thereby to draw two parallel cuts on this flooring material, stripping the sheet flooring material between these cuts to thereby form a joint-forming grooved portion provided with a masking along side edges of stuck sheet flooring material and charging this grooved portion with a joint material. This process permits to obtain various patterned ornamental joints.

Abstract: This process of forming ornamental joints comprises sticking a sheet flooring material onto a floor base, thereafter drawing one desirably outlined standard line on the thus stuck sheet flooring material, then sliding one cutting blade of a cutter with a pair of cutting blades, disposed leaving a space corresponding to the joint width therebetween, on the sheet flooring material along the standard line to thereby form two parallel cuts on the flooring material, stripping the sheet flooring material between these cuts to thereby form a groove for forming a joint, and charging the grooved portion with a joint material. According to the process like this, there can be obtained ornamental joints of various patterns.
