Now a day there is different manual and automatic hank reeling machine. Hank reeling machine used to reel cone yarn to hank yarn form. Automatic hank reeling machine works by use of electric power system and has motor for hank reeling. This machine can wind a maximum number of hanks within one reeling cycle of machine. It’s less time consuming, but expensive.
Hand hank reeling machine can wind single hank per reeling cycle and its time consuming than automatic reeling machine. Based on data analysis, the researcher designed and fabricated manual hank reeling machine which can be driven easily by using foot. This machine can wind up to 12 hanks within single hank reeling cycle.

In the textile industry, a hank is a coiled or wrapped unit of yarn or twine (as opposed to both other objects like thread or rope as well as other forms such as in a ball, cone, bobbin, spool, etc). This is often the best form for use with hand looms, compared to the cone form needed for power looms. Hanks come in varying lengths depending on the type of material and the manufacturer. For instance, a hank of linen is often 300 yards (270 m), and a hank of cotton or silk is 840 yards (770 m). While hanks may differ by manufacturer and by product, a skein is usually considered 1/6th of a hank (either by weight or by length). One source identifies a skein of stranded cotton as being 8.25 yards (7.54 m), of tapestry wool as being 10 yards (9.1 m), and crewel wool as being 33 yards (30 m) [1-2].
In yarns for handcrafts such as knitting or crochet, hanks are not a fixed length but are sold in units by weight, most commonly 50 grams. Depending on the thickness of the strand as well as the inherent density of the material, hanks can range widely in yardage per 50 gram unit; for example, 440 yards for a lace weight mohair, to 60 yards for a chunky weight cotton. Special treatments to the materials that add cost, such as mercerisation or laborintensive hand-painting of colors, can influence a manufacturer’s desired length per unit as well. Knitters and crocheters rewind the hanks into balls or centre-pull skeins prior to use, in order to prevent the yarn from becoming tangled.
Hog casings are sold in “bundles” or “hanks.” This unit of measure equals 100 yards (91 m) [2].
Hank reeling machine is used to change cone or cop packed yarn into a hank form by winding a yarn into a circular or round shaped reel. Hank yarn used to produce knitted and woven fabric [3-4].
Local knitted and woven fabric producers can purchase a cop packed yarn from market and they change into hank form by using small manual hand driven hank reeling machine. However, the amount of hank produced by manual reeling machine does not satisfy the need of small scale knitted and woven fabric producers and it leads the hank cost very high. Therefore, this problem was a notable hindrance limiting the industrial growth of the country. The author concerned on fabricating of easily operated manual reeling machine with less manufacturing cost and which rotates by using foot and can wind more number of hanks per cycle.

This machine has a feeding unit to feed cone or cop packed yarn to the reeling unit. There is a yarn traverse rod used to distribute the yarn throughout the hank width. The machine has worm gear with 100 teeth number. The worm gear is connected with the shaft by belt. A small length rod is welded on the worm gear there is a small length rod. In yarn traverse rod a small key like tongue is connected. During reeling, when the shaft rotates one cycle, one of the worm gear teeth forward and a small rod on the worm gear pushes the key like tongue welded on yarn traverse rod. Yarn feed welded on yarn feed Yarn traverse distribute the hank yarn uniformly throughout the width of hank.
Fabricated Manual Hank reeling Machine
As indicated in Figure 4, the fabricated manual hank reeling winds 12 hanks per reeling cycle. The produced hank yarn is distributed uniformly throughout the width of hank.
