ABSTRACT:
A method of manufacturing oblong wooden articles to be used for the manufacture of coherent pairs of chopsticks includes punching or cutting the articles out of veneer sheets along outer straight lines resulting in outer surfaces (6 and 7) being formed. These surfaces are preferably inclining slightly towards one another and extend over the entire length of the articles. The articles are simultaneously provided with a cut along the plane of symmetry between the inclining surfaces (6 and 7), which results in a short uncut portion at the thickest end (9). This cut (8) along the plane of symmetry extends only partially through the articles in the transverse direction thereof, whereby a bridge-creating portion (10) is present between the parts (2 and 3) of the articles. This bridge-creating portion (10) is optionally automatically removed at a succeeding processing involving a bevelling (11-18) of the parts of the article.
