The difference between the big shuttle and the small shuttle of the sewing machine
There are many components of a sewing machine. Many people don’t know the functions of some of the components, or the differences between different models of the same component. Let’s talk about the difference between the large hook and the small hook. The rotary hook is an important part of the sewing machine, and the lock stitch sewing machine is the most common in the sewing equipment. The rotary hook can be divided into large rotary hook and small rotary hook. The stroke of the thread take-up lever of the large rotary hook is relatively large. Generally, the large rotary hook has twice the winding amount of the standard rotary hook. It is used for sewing thick fabrics and thick fabrics. This type of hook is mostly used in industries such as leather goods, luggage and bags.
The small rotary hook can also be used for thick thread and thick materials, but the effect is obviously not as good as the large rotary hook, the amount of winding is less, and the stitches are not as good as the large rotary hook. The small rotary hook is mainly used in the clothing industry.
