Abstract: This paper explains the space position of traveler in spinning by considered eccentric-force FMy,it take shape of line u and line w on the coordinate plane x’Ay’ and y’Az’ respectively.As regard to u the inclined angle κ > 0,∠κ = ∠δ,and by calculation angle δ is litter,but this shows that the outside edge of traveler must lead the inside edge.As regard to w the incline angle χ shows traveler tilt front ward,resulted in that the yarn passage height of traveler decreases.However to analysis ratio q /s and value s at point J the result as traveler tilt front ward big and yarn passage litter be referred to mass-center low and traveler-shapes litter is shown.As to angle τ being the shape of traveler on coordinate plane x’Az’ tilt outward referred to initial ordinate,it could be measured from the force-diagram.The obliquity of traveler shape is not able to avoid in spinning,then the value c must be obtained from balloon.According to the value τ and c /a calculated value τ0v will be the minimum of angle τ0.Angle τ0 has to be obtained from the bottom arc radius r1 on the traveler being in contact with ring by arcual surface,then should be to attend line A0M0≌AMv.Every traveler posses a contained line A0M0,its length and obliquity had been set,so it becomes technology feature data.This idea is very useful to profile and use traveler and ring.
