in shuttle looms, while cones are better suited for
industrial looms. Fig 6
• Adaptability to different looms: The choice of
package can be adapted to the specific type of
loom being used, optimizing the weaving process.
4 Cost-effectiveness
• Reduced waste: Proper packaging minimizes yarn
waste due to breakage, tangles, or contamination.
• Efficient storage: Some packages are more
space-efficient for storage, reducing storage costs.
Yarn packages are not merely containers, they are
integral tools that significantly impact the efficiency, Sources
quality, and overall success of the handloom weaving • Restriction in the rotation of the winding spindle
process. By carefully selecting the appropriate package,
weavers can optimize their workflow, minimize waste, • Improper setting of cone holders
and produce high-quality textiles. • Cam switch set improperly
Types of wound package defects and remedies • Loading of lint in the groove of builder cam

The following are the important defects that commonly Corrective action
occur in wound packages:
• Cone winders are to be overhauled periodically
Stitches on cone
• Anti-patterning device is to be checked regularly
This is due to improper laying out of ends onto the cone at
the reversal of yarn path. It causes more end breakages • Cone holders are to be properly lubricated so as to
in the subsequent processes and also leads to excessive ensure their free movement
yarn waste. (Fig 5) Soft package

Fig 5 It is caused due to abnormal softness of the structure
of the package. In this case, the overall density of the
package is lower. It results in soft packages either at the
base or at the nose of the cones. (Fig 7)

In this type of defect, a ribbon-like structure is formed on
