Pfaff triger kayışı
When it comes to the timing belt (toothed belt) of sewing machines, something has already been written on that topic on the blog. The topic was general and we described the general concepts of timing belt on sewing machines, today in this topic I will write about the toothed belt for vintage pfaff sewing machines, these are belts made of cords with the addition of metal rings (cleats). For many years, the timing belt for sewing machines has not been made in this way, today it is made of special rubber woven with threads. I can only guess why the belt was then made of cords and metal cleats.?
