            Shawl Weaving Artisan - Winding and Warping

            Identifying properly wound warp yarn on beam

            Objectives : At the end of this exercise you shall be able to
            •  inspect and identify whether the warp yarn is correctly and uniformly wound on the weaver’s beam.

              Requirements

               Tools/Equipment’s/Instruments
               •  Warping machine                  - 1 No.        •  Measuring tape                     - 1 No.
               •  Warp beam with warp                             •  Notebook                           - 1 No.
                  (correct and faulty samples)     - 1 No.        •  Pen                                - 1 No.

            •  Stand directly in front of the beam.                               Measure width at
            •  Check for flatness: The surface of the warp should          Position on                Even? ( /X)
               be even and flat.                                   S.No.                 Width (cm)

            •  Check for tension variation: No loose or tight ends
               should be visible.                                    1    Left End
