These holders are arranged so that the long axis of the fiber piece 6 and the long axis of the fiber 1 are aligned (first
Diagram a). The fiber strip 6 as well as the fiber 1 are each chucked in only one holder, so that in the section 7 they are completely free from torsional stress.

The fiber 1 is chucked into two holders 2.3 and 4.5 (FIG. 2a), and then somewhere between the two holders is instantaneously heated to the melting point (FIG. 2b). This removes the torsional stress in the section 8 of the fiber. after that,
The next step, the scratching and cutting of the fiber, is carried out as described above (Figures 2C and 2d).a In a third method, the fiber is removed a few cm from its end and in a suitable manner. Chuck it into the first holder. The end of the fiber is then placed in a liquid that solidifies later, such as tin wax or glue, and the end is chucked by assimilation.
