The Siruba BT-439Q is a specialized, electronically controlled button sewing machine designed for attaching buttons with a shank. It uses a durable lockstitch (instead of a chainstitch commonly found in mechanical button sewing machines), which provides significantly stronger and more secure fastening—ideal for garments requiring high durability.
The machine is equipped with an easy-to-use control panel that allows the operator to select from 50 built-in stitching patterns and create up to 200 custom patterns. It features automatic thread trimming and presser foot lifting for increased efficiency. The integrated 550W servo motor with a Direct Drive system ensures quiet operation and energy savings. This makes the BT-439Q an excellent choice for both mass production and high-end garment manufacturing.
