In the warping machine, the string unfastened from the rollers gets static charges along the way from the out of the warp to the twisting combs. These static charges make thinner strings round and break. Then, this causes the breakdowns of the machine and lost of the time and working.

Since the ionization pins are directed to the strings, H&O Antistatic bars should be positioned under the out of the warping. Thus, the bars neutralize the static charges on the strings and solve the problems created by the static. Also, antistatic bars can be put at the out of the combs for the neutralization of the combing area.
