Classification of warping
Warping is mainly classify
into three part
1. Beam Warping
2. Section Warping
3. Ball Warping
Beam Warping
A. Yam is directly wound from cone onto the beam B.
This process is suitable for single color weaving C. The end product is
called warp beam and must sent to the sizing department for further process
Types of Beam Warping Machine
The warping machine are classified according to the package drive,
there are two basic types of the warping machines
(i) Direct
driven or the spindle driven in which yarn winding speed on to the beam
increases as the diameter of the beam increases. Beam size is therefore limited
due to the increase in yarn winding tension
(ii) Surface
driven, in which beam gets its motion while in contact with a drum, revolving
at fixed rpm In this case yarn winding speed remains constant throughout the
build of the beam.
Section Warping
1. Yam is wound firstly wound onto a drum and
then wound onto the beam.
2. This process can be used for both single or multi color
weaving.
3. The end product is called Weavers beam and can
be directly installed onto the weaving loom.
Ball Warping
1. Ball warping is an intermediate process for
storing yarn for transport, dyeing or reserve.
2. It does not produce a beam.
3. The usual form is a cross wound cheese in
which multiple ends are wound at the same time in a ribbon which contains
perhaps 50 or a 100 ends.
