Watch our video «39_Revolutionary ZARIF sewing technology 2021-Disadvantages of existing technologies stitch #301_401» in our YouTube channel, where we have shown in detail the eternal disadvantages of these existing technologies.
DISADVANTAGES OF EXISTING TECHNOLOGIES FOR FORMING A LOCKSTITCH TYPE 301
All the disadvantages of existing technologies for forming a lockstitch type 301 are inextricably linked with the use of a hook (shuttle), inside which there is a bobbin with a bottom thread.
Attention: No matter how much the technology of forming a lockstitch type 301 develops in the future, it is impossible to eliminate the disadvantages associated with using a hook, since it is impossible to get a lockstitch without using a hook.
