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.
Claims12
A rotating head for deforming the edge of ballpoint pen nibs, said rotating head comprising:
- two rotating rolls installed to be freely pivotable in said rotating head, and having forming disks with front surfaces spaced apart by a gap;
- and
- a tongue extending through said gap and comprising a V-shaped front face moveable against a spring;
- wherein said rotating rolls are freely rotatable about coaxial axes.
A rotating head for deforming the edge of a hollow ballpoint-pen nib, said rotating head comprising:
- a pair of forming disks rotating about the same axis, each forming disk having a front surface and a rotating profile configured to shape the edge of a nib, said rotating disk front surfaces being spaced part by a gap so that said rotating profiles are adjacent each other to shape a nib positioned therebetween.
