ABSTRACT:
A device for edging points of ball point pens wherein three equiangularly spaced rollers run on a conical surface. The point to be worked is moved into a working zone defined by regions of the three rollers in a direction along the axis of the conical surface in a direction from the apex of the conical surface towards the wider end of the conical surface. The rollers either react against a rotatable disc or a fixed shaft, in which latter case the conical surface is rotatable.
