The document outlines three main types of yarn packages: parallel wound, near parallel wound, and cross wound. Each type has subcategories and specifications, such as warp and weavers beams for parallel wound packages, pirn and cop packages for near parallel packages, and cone and cheese packages for cross wound packages. Benefits and drawbacks of each package type are discussed, including stability, yarn withdrawal, and the need for flanges.

2. TYPES OF PACKAGES: -
1. Parallel wound packages
(a)Warp beam
(b)Weavers beam
2. Near parallel wound package
(a)Pirn
(b)COP
3. Cross wound package
(a)Cone
(b)Cheese

3. 1. Parallel Wound package: -
• In case of a parallel wound package, the threads are placed parallelly
and at a angle of 90 degree with the axis of the package.
• Flange is needed so that the coils can not be slipped from the package
Coils are placed at 90 deg with
the package axis

4. (a)Warp Beam: -
• Used to prepare a continuous length of yarn that is known
as warp
• Yarn is wound onto a cylindrical core called Beam
• Flanged at both end to prevent the slippage of yarn.
• Yarn is wound at a constant tension

5. (b)Weavers Beam: -
• Used to prepare a continuous length of yarn that is known as warp
• Unlike a warp beam, it is larger in size.
• Yarn is wound onto a cylindrical core called Beam
• Flanged at both end to prevent the slippage of yarn.
• Yarn is wound at a constant tension and generally used in weaving
industry.

6. Advantages:-
• Sideway withdrawal is possible
• Many yarns can be wound at a time
• No need of traversing machine here.
• The density of yarn is more.
Disadvantages: -
• Flange is necessary at each end
• Can not be over withdrawal

7. 2. Near Parallel Wound package: -
• Threads are placed nearly parallel with the axis of the package.
• Flange is not needed
(a) Pirn package: -
• Pirn is prepared by the pirn winding
process
• Package is produced by the help of
reciprocating progressive traverse of
thread
• Pirn is a small package that is
produced from bigger package

8. (b) COP package: -
• COP stands for Creel less open package
• Commonly used in spinning industry
• Package is wound onto a cylindrical core
at a slight angle which creates a conical
shape. It allows the yarn to be removed
easily from the package

9. Advantages:-
• No need of flange
• Can be side and over withdrawal
• No change of yarn turns per inch during winding
Disadvantages: -
• Need of traversing mechanism
• The Package is not stable.

10. 3. Cross Wound package: -
• Consist of single thread, which is laid on the package at an
appreciable helix angle
• Most stable package and no need of flange.
(a) Cone package: -
• Most commonly used package
• This type of packages are produced by
placing the yarn onto a conical shaped core.
• It is the type of package where the diameter
of the package is changed throughout the
length
• The top end is Nose and the bottom end is
Base.

11. (b) Cheese package: -
• This type of packages are produced by
placing the yarn onto a cylindrical shaped
core.
• It is the type of package where the
diameter of the package is constant
throughout the length of package.

12. Advantages:-
• No need of flange
• Over withdrawal is possible
• High stability of packages
Disadvantages: -
• Need of traversing mechanism
• Yarn quality is less here
• Chances of insertion of twist during over
withdrawal.
