This essential component connects the foot-powered treadle mechanism to the handwheel, transferring rotational energy generated by the operator’s feet. Typically made of leather, rubber, or fabric, it forms a crucial link in powering the stitching process.
Providing the driving force behind antique and vintage sewing machines, this linkage is fundamental to their operation. Its presence allows for self-sufficient, non-electric sewing, embodying a historical connection to pre-industrial manufacturing. The rhythmic motion required to operate the treadle also often contributes to a unique, kinetic experience appreciated by many sewists.
