MACHINE FOR EMBOSSING TYPE-WHEELS OF ROLLERS FOR OFFICE MACHINES

摘要

Apparatus for the embossing of type on cylindrically shaped members, e.g., wheels or rollers is described. The die is a flat rectangular member with a surface thereof forming the active surface for embossing characters on to a semifinished wheel or roller. The flat active surface is reciprocated longitudinally of itself and in a direction perpendicular to the axis of the wheel or roller being embossed. In one embodiment the reciprocal motion of the die simultaneously rotates the semifinished wheel, while it is pressed against the latter. In a second embodiment a semifinished roller is pressed between diametrically opposed slides. These slides are caused to reciprocate in a direction perpendicular to the axis of the roller and 180 DEG out of phase with respect to each other. The active surface is on the surface adjacent the roller on one of the slides.
