Button-Attaching Machine

One of the most important features of this machine is the well-made multiple cam which has many functions to perform. By its control of the clamp the needle is enabled to enter the separate holes in the buttons; it operates the thread cutting mechanism and the thread nipper mechanism, and automatically stops the machine when the button has been stitched. The cam is accurately cut by automatic machines which makes great precision possible.
