The SIRUBA® R728K-224 is a double-needle industrial post-bed lockstitch sewing machine designed for professional sewing operations involving curved, shaped, and three-dimensional textile products. Its elevated post-bed construction provides convenient access to areas that can be difficult to handle on conventional flatbed sewing machines.
Featuring a combined needle-feed and drop-feed mechanism, the R728K-224 is designed to support controlled fabric movement during sewing. This feeding configuration is useful for selected layered materials and sewing operations where consistent material positioning is important.
The double-needle arrangement allows two parallel rows of lockstitch sewing, making this model suitable for selected footwear components, leather accessories, shaped textile products, and decorative topstitching applications.
JMJ Sewing Machines supplies the SIRUBA® R728K-224 as a complete industrial sewing workstation with an external servo motor, industrial sewing table, and heavy-duty stand.
