The correct answer is
Decease in traverse speed
Sectional Warping Drum Taper Angle Effect
The taper angle of a sectional warping drum influences how yarn is wound onto its surface.
- A larger taper angle means the drum's diameter decreases more rapidly along its length.
- This creates a steeper slope for the yarn as it traverses back and forth.
- To ensure even yarn layering and prevent issues like yarn build-up or slackness on this steeper slope, the speed at which the yarn moves across the drum (traverse speed) must be adjusted.
- An increase in the taper angle normally requires a decrease in the traverse speed. This allows the yarn more time to settle correctly, maintaining uniform tension and density across the wound package.
Therefore, an increase in taper angle on a sectional warping drum will normally require a decrease in traverse speed.
