Even if it says "sewing-machine parts" in a word, there are various parts(200-400 parts) to manufacture one set of sewing machine. There are only about ten parts currently produced to our company among them. However, since parts are also different by each maker exception and type exception and model, the parts total in which ‚¸ produces the parts of ten numbers per set to our company serves as what to no less than 2,000-3,000 kinds.

Needle bar driving lever
Since it has separated to the double, although this part is called
"double crank", it may change greatly with the differences, the

Feed bar
When sewing cloth by the sewing machine, if a pedal is stepped on, cloth
will be feed in front automatically.  It is the duty of the feed bar. |

Rod
The role of a Rod is mainly changing rotational movement into
reciprocating movement, or changing reciprocating movement into rotational
movement conversely united with a crank. Like a photograph, there are
all kinds of size is chosen by power transfer into a near portion, or power
transfer into a portion far from.  |

Looper
    A looper makes a loop with thread as the name. The loop makes the special seams (elastic that etc.) different from ordinary straight-line sewing constitute. If you see a right sketch, although it will think whether you can understand, the position relation of a looper and a needle is quite severe. In wonderful rotation 5000-10000rpm, since it is the parts which is carrying out the precise motion. |
