Applications and Experiments for the Button Hole Sewing Machine
Trainees set buttonhole length and stitch density, sew test holes on scrap fabric and then on shirts, blouses and trousers, learning how stitch count affects strength and appearance. The machine suits garment production training and is a standard specialised station in vocational training equipment lists for apparel workshops.
- ITI Sewing Technology trade: specialised machine operation for buttonholes.
- Apparel production and fashion diplomas: finishing shirts, blouses and trousers.
- TVET garment workshops: setting stitch density from 54 to 345 stitches for different fabrics.
Buttonholes are usually sewn after the main seams and before the buttons are attached, so this machine is typically placed near a button attachment station.
Standard Scope of Supply
The machine is supplied as a single unit on its metallic frame with the 1/3 hp induction motor. The listing mentions that the machines come in various sizes but gives no accessory list, so the quotation confirms the version offered and any stand, table or accessories included.
Packing, MOQ and Lead Time
Ask for one buttonhole machine or several for a production-line workshop. The quotation lists packing, delivery time and price for that quantity; with a 75 kg gross weight, it also names the packing used for shipment.
