Winding Tension Control and Measurement
topic
Winding tension control maintains constant yarn tension throughout package build as supply package diameter decreases from full to empty, using dancer roll or electronic tension sensor feedback systems adjusting delivery roll speed or brake force to compensate for the increasing withdrawal speed from decreasing package circumference, with tension uniformity within plus or minus 10 percent of target across the full package life being the specification for warp yarn packages requiring consistent density for reliable warping performance.
Role
Governs the cross-sectional density uniformity of wound packages that determines whether yarn unwinds at consistent tension from core to surface during warping, with tension-wound packages providing the uniform density essential for consistent warping tension that produces warp beams with equal yarn length and tension across all ends, preventing the differential yarn lengths and tensions that cause weaving problems from uneven shed formation and warp break rate variation.
