Bar Tacking Machine

The bar tack machine has many applications in the clothing industry ;one of them is the sewing of a dense tack across the open end of a buttonhole.

The machine sews a number of stitches across the end of the buttonhole, and then over sews them at right angles with a series of covering stitches. Each machine sews fixed number of stitches with an option to change stitch density and machines are available which sew bar tacks containing from 18-42 stitches. Belt loops of trousers can also be bar tacked with these machines. The other features available are:

1. A mechanism, which signals audibly and visually when the bobbin thread is below a certain level.
2. Automatic thread cutting
3. 2-stage pedals which opens and closes the work clamp and also operates the machine.
4. A brake wheelbase, which enables the machine to be easily moved.

In other specialized versions, bar tack machines are used for sewing small decorative tacks and shapes.
