It generally includes the main parts such as the machine head, machine base, transmission system, feeding mechanism, needle and thread system, etc. The machine head is the key part of the sewing action, usually including the needle bar, hook and other parts, which are responsible for driving the needle and thread to complete the sewing operations such as threading the needle. The machine base provides stable support for the whole machine. The existing ribbed hems are usually sewn manually on sewing machines. This method requires multiple manual alignments and manual cloth feeding during sewing, which usually takes a lot of time and requires the operator to be a skilled worker.

[0015] Working principle: The overall process of the equipment is: start the machine - put on the ribbing - the electric eye senses the cloth - the left stick mop wheel pulls the ribbing to automatically find the hub position and align it - the second layer of ribbing is put into the reverse bone - automatic alignment - the left roller mop wheel mechanism stops working.

[0016] The specific operations are as follows: Power-on initialization: open the motor to the left, touch reset, and leave the origin to reach the lower layer opening position; Put in the inner material layer: use both hands to hold the material open and put it in at the same time. The right side moves forward to the electric eye and then moves back to the position (or start manually). The left side holds the material open and moves to the left to the stock-finding position. Then pull the mop wheel down to press the cloth.
