What do you mean by sectional warping?
In section warping, warp yarns are organized into yarn bands (sections), each having the same warp density as for the weaver’s beam. The warp yarns are wound onto the drum band by band until all yarns are wound onto the drum. Then, the yarn sheet is transferred from the drum onto the weaver’s beams.
Why is sectional warping needed?
Sectional warping is one of the important processes of textile weaving where equal length of yarn is wound first in small sheets or sections on a drum. After that, it is transferred to the beam from the drum in the form of a sheet.

How many types of warping are there?
two methods
There are normally two methods of warping employing different technologies: direct warping or direct beaming (also sometimes known as beaming) indirect warping/sectional warping.
What is a sectional warping machine?
Sectional warping machines can be divided in two zones: warping and beaming. The warping zone can be divided into two parts: the creel and the warping drum. Creels have been described in the earlier section. Normally H-creels with a certain amount of automation are used in sectional warping.
