Lesson 23 : Other Sewing Machines

Button sewing machine

Buttons with two holes, four holes or shanks can all be sewn on the same machine by simple adjustment to the button clamp and the spacing mechanism. The sewing action consists of a series of parallel stitches whose length is equal to the spacing between the centers of holes. The needle has a vertical movement and the button is moved from side to side by the button clamp. Buttons can be sewn on with one or two threads. Each machine has a maximum number of stitches i.e. 16, 24 or 32 and can be adjusted to sew the full amount or half i.e. 8 or 16, 12 or 24, 16 or 32.

Generally decorative buttons will be sewn on with half the number of stitches used for functional buttons. Where a ‘neck’ is required on the under side of the button, stitch length between button & the garment is increased and finished with a whipping action performed as a separate operation.
