Drive the structure of false twisting spinning for bottom roll or front upper roller before the two contact-segment incrementals of the described not isometrical double-wheel-disc of Fig. 9 Figure 10, because the second wheel disc is D2/D1 with the diameter ratio of the first wheel disc and the ratio of linear velocity, if therefore do not calculate the smooth of false-twisted process, suppose that namely false twisting efficient is 100%, then according to technology Calculation, spin the sliver of any line density, the false twisting twist factor that the second wheel disc gives first sliver is metric system 860 * D2/D1,9 * D2/D1 made in Great Britain.The first wheel disc directly contacts with front upper roller or front lower surface of roller, the linear resonance surface velocity of wheel disc periphery is substantially equal to front upper roller or front lower surface of roller linear velocity, be substantially equal in other words the output line speed of sliver, if therefore do not calculate the smooth of false-twisted process, suppose that namely false twisting efficient is 100%, then according to technology Calculation, spin the sliver of any line density, the metric system false twisting twist factor that gives sliver behind the first wheel disc is about 860, false twisting twist factor made in Great Britain is about 9.
When configuration D2＜D1, sliver obtains first false twisting twist factor that the second wheel disc gives sliver gives sliver less than the first wheel disc after this false twisting twist factor, the false twisting twist of two contact-segments is cumulative, namely the second wheel disc is to first false twisting twist factor of sliver of front roller nip output, and sliver first wheel disc of reentrying after through the gap between the one the second wheel discs replenishes the false twisting twist factor that gives sliver.Such as D2/D1=0.8, then the second wheel disc gives first the false twisting twist factor of sliver=860 * D2/D1=688, and the metric system false twisting twist factor that gives sliver behind the first wheel disc is about 860.
