Title (EN) TIP OF BALL-POINT PEN AND METHOD OF MANUFACTURING SAME
(FR) POINTE DE STYLO BILLE ET SON PROCEDE DE FABRICATION
Abstract: front page image
(EN)A method of manufacturing a metallic tip of a ball-point pen, which is formed at an outer surface of a small opening thereof with a plurality of circumferentially extending caulking portions which are differently angled to hold a ball, said method comprising causing a pressure contact portion of a caulking device, which serves to form the caulking portions, to abut against the ball at caulking. Preferably, the pressure contact portion of the caulking device is formed by a continuous pressure contact surface which has a plurality of different caulking angles, and the pressure contact surface is caused to pressure contact with the tip of a ball-point pen whereby the caulking portions having a plurality of angles are formed in a single process.
(FR)L'invention se rapporte à un procédé de fabrication d'une pointe métallique de stylo bille qui est formée autour d'une surface externe d'une petite ouverture du stylo par une pluralité de parties de matage s'étendant sur la circonférence qui forment des angles différents afin de retenir une bille. Ce procédé consiste à placer une partie de contact sous pression d'un dispositif de matage, servant à former les parties de matage, contre la bille. De préférence, la partie de contact sous pression du dispositif de matage est continue et présente plusieurs angles de matage différents, et la surface de contact sous pression vient en contact avec la pointe du stylo bille, ces parties de matage présentant plusieurs angles formés selon un procédé unique.
