ABSTRACT:
The invention relates to a device called a rotating head which is used to deform the edge of the points or nibs of ball-point pens. The inventive device has two rotating rolls which are installed so that they can pivot freely in the rotating head. The rotating rolls can turn freely around aligned axes. The rolls each have forming disks and are arranged to define a gap between the front surfaces of the forming disks. A tongue having a V-shaped end face is disposed in the gaps and can be moved against a spring. The tongue engages a tip ball in a nib positioned between the rotating rolls to be formed into a finished nib.
