Working Principle of Beam Warping Machine:
In beam warping, the yarns are withdrawn from the single-end yarn packages on the creel & directly wound on a beam. Direct warping is used in two ways:
- Beam warping can be used to directly produce the weaver’s beam in a single operation. This is especially suitable for strong yarns that do not require sizing such as continuous filaments & when the number of warp ends on the warp beam is relatively small. This is also called direct beaming.
- Beam warping is used to make smaller intermediate beams called warper’s beams. These smaller beams are combined later at the sizing stage to produce the weaver’s beam. This process is called beaming. Therefore, for if the weaver’s beam contains 10,000 warp ends, hen there would be-say – 10 warper’s beams of 1,000 ends each. If this weaver’s were to be made an one stage, the creel would have to have 10,000 yarn yarn packages, which is impossible to manage.
How to Improve Beam Warping Process?
Beam warping process is the most progressive process ensuring a high quality of produced warps & high efficiency. In cotton weaving, beam warping is mostly used.

- Better uniformity in the tension of individual yarns are the provision of adjusting the tension of separate groups of warp yarns over the height of the warping creel.
- Enlarging the mass of bobbins & warping beam winding.
- Increased number of bobbins when warping yarn of low linear density & a greater number of yarns in the warp.
- Improved shape of winding on the warping beams & uniformity of the specific density of winding.
- Higher accuracy in warp measuring & reduction of wastes caused by irregular unwinding of warps from the beams at sizing.
- Compensation of warp tension at starting & stopping of the machine & slow running at starting a new warping beam.
- Increase of labor productivity in warping by partial or full automation of bobbin change.
