PURPOSE:To make it possible to machine the circumference of a small shaft so as to have a precision finish surface and to transfer a tape with the small shaft without giving any damage by compressively interposing a small shaft between two feed rollers and a small burnishing roller. CONSTITUTION:When feed rollers 2 are rotated, a small shaft 1 having a diameter of 2.5mm or less which is placed between a pair of feed rollers 2, 2 rotates. With this rotation, a burnishing roller is also rotated. The projections of the small shaft 1 for tape guide are crushed with the burnishing roller 4 to machine the circumference of the small shaft 1 so as to have a precision finish surface. The damage of a tape guided with the small shaft can be prevented. |
