Brother is one manufacturer of sewing machines which produced the Buttonmatic. This particular brand of sewing machine has a button-sewing foot that is used for sewing buttons. There is typically a diagram or sticker, somewhere on the machine, that shows how to thread the needle. However, if this diagram is missing, instructions will be needed to complete the task. This will require that you become familiar with how the thread runs through the machine before it goes into the needle.
Find and raise the presser foot that is just above the needle on the sewing machine. Move the presser foot up as far as it will go.
Insert the end of the thread into the eye that is on the upper thread guide. Run the thread through the upper thread tension discs.
Pull the thread down to provide a bit of slack, and then position it up and through the thread guard. The thread will need to be positioned from the left side to the right. This will allow it to catch on the thread check spring.
Insert the thread into the eye that is on the thread take-up lever. The thread will again need to be positioned from the left side to the right.
Pull the thread down to provide a bit more slack, and then insert the thread into the thread guides.
Insert the thread into the needle from the front to the back. Pull the thread so there is at least two inches coming out from the needle.
- If the threading is not done in the proper order, the thread may break or cause skipping when stitching.
