概要

This instalment deals with the non-friction type tension regulator. The elongative property of yarn must be considered in the use of this type of regulator. The following approximate equation is given to the relation between yarn tension and the regulator's characteristics : l dΔ Ta + Va Δ Ta = VsTa⁄pa ps⁄T8 ΔTs+Ta⁄pa(Va pa −Vsps), where l : length of draft zone Va : deliverly velocity of yarn Vs: supply velocity of yarn Ta : mean value of yarn tension on the deliverly side Ts : mean value of yarn tension on the supply side pa : mean value of yarn linear density on the deliverly side ps : mean value of yarn linear density on the supply side ΔTa : variable component of yarn tension on the deliverly side ΔTs : variable component of yarn tension on the supply side. Some results are explained theoreticaly on the basis of this equation.
