ABSTRACT:
A process for preparing a tape guide cylinder is disclosed, which includes the steps of deep-drawing a sheet metal material progressively to form an elongated cylinder with a bottom, subjecting the resulting cylinder to flange-machining to form a flange at its open end, thereafter removing the bottom of the cylinder, subsequently trimming the flange from the cylinder, and finally subjecting the resulting cylinder at either of its ends to a beat-machining for finishing the shape of the elongated cylinder.
The tape guide cylinder thus prepared may further be subjected at its circumference, to a precision finish for providing an outer diameter of less than 6 mm but more than 5.2 mm.
