Before you choose
Questions about this machine.
Which automatic functions are included?
The catalogue lists electric lifting, trimming and automatic sewing-control functions. Send the required workflow so the quotation can identify the supplied mode, attachments and suction arrangement.
Can it sew stretch materials?
Knitwear is among the catalogue applications. Share fabric composition, stretch, layer count and the desired seam so that differential-feed settings and the machine configuration can be reviewed.
How do I compare a high-speed overlock machine for my line?
Compare its catalogue speed with the actual handling cycle, seam length and fabric response. A maximum speed figure alone cannot establish daily output. Send the current operation and required seam so we can review the complete configuration.
