Shawl Weaving Artisan - Winding and Warping

Introduction of winding and warping machine

Objectives: At the end of this lesson you shall be able to
• explain winding
• list types of winding
• brief types of winding machines
• explain warping
• brief types of warping
• list parts of warping machines.

1 Winding: Winding is to convert yarn from bulk form Spindle Yarn wound by rotating spindle. Used for
(like hank, skein, or bobbin) into a suitable package Winding pirns.
(like cone or pirn) that is ready for use in warping,
weaving, or dyeing. (Fig 1) Automatic Has sensors, automatic knotters, and
Winding yarn clearers. Faster production.
Fig 1 Working process (Drum winding example)

1 Yarn comes from supply cone or hank.
2 Passes through tensioner and yarn clearer.
3 Travels over guide and onto rotating drum.
4 Drum rotates and moves guide left-right (traverse).

5 Yarn winds uniformly onto the cone.
Functions of winding 6 Machine stops automatically when cone is full or yarn
breaks.
1 Create yarn packages that are easy to handle.
2 Warping
2 Remove yarn faults (knots, slubs).
Warping means arranging multiple yarns parallel to each
3 Add uniform tension to yarn. other, wound with equal length and tension, ready for
4 Create packages suitable for high-speed machines. weaving.
Types of winding Main types of warping

a Precise winding a Direct warping (beam warping)
• Yarn winds in an exact pattern (cross or parallel). • Yarn from cones is wound directly onto warp beam.
• Common in shuttle less loom pirns. • Used when colour pattern is simple or single
colour.
• Slower but neat and compact package.
• Fast and efficient (Fig 2)
b Random winding
• Yarn winds freely in layers.
• Faster winding.
• Used for cones and general use.
Types of packages
• Cone: Used in weaving/knitting.

• Pirn: Used in shuttle looms.
• Bobbin: For spinning/weaving.
• Cop: Small cylinder, often used in ring spinning.
