Tension Relief
Control of warp tension peaks during the loom cycle is necessary to avoid thread breakage in delicate flax yarns. The mechanism of dynamic ease off performs this task by momentarily shifting the whip roll or back rest closer to the heald frames at the exact moment of beat-up. This mechanical relief prevents the high tension peak that occurs when the reed forces the weft yarn into the fabric fell, protecting the low elasticity fibers.
Mill loom adjustment sheets record this setting to match the specific yarn count being woven.
Looping Control
Weaving high density linen fabrics puts immense stress on the warp threads due to the tight packing of the weft. The dynamic ease off reduces the warp tension when the shed is at its widest and during beat-up, ensuring the yarn does not fail under tension. It is synchronized with the main loom shaft through a set of adjustable eccentrics or electronically controlled servo motors.
By fine tuning this movement, technicians can weave dense fabrics without risking micro fractures in the linen fibers.
Quality Preservation
Structural weakness in woven linen often stems from yarn damage during weaving. Use of dynamic ease off protects yarn integrity, preventing fabric slips under tension. It is a parameter checked during standard mill quality audits.
