Hair which is sewn at the top end either by machine or by hand is known as hair weft. Hair sewn by machines are known as machine made weft and similarly hand sewn hair is termed as hand-tied hair weft (hand made weft). Any weft usually weighs around 100 gm. Depending on their type they are categorized into different grades.
Professional HAIR WEFTING MACHINE SET consists of a combination of High Speed Double & Single Needle Lock Stitch Industrial Sewing Machines. In all, three machines will be fixed in one table and functions as mentioned below.
When the hackled and cleaned human hair is placed in the first machine, it sews the hair with the double needle and pushes the hair to the next machine for making a thin weft and in turn folds the hair and sends it to the third machine which stitches further and runs it to the glue box where a glue is applied on a roller atop the wefted hair to prevent hair fall. Then the weft is further stitched using the single needle sewing machine to produce the final product.
