The Siruba BH-9820-02 is an advanced electronic buttonhole sewing machine designed for precise and efficient buttonhole creation in garment production. Powered by a built-in energy-saving servo motor and driven by stepper motors controlling key mechanisms, the BH-9820-02 offers quiet, smooth, and highly customizable operation. It supports sewing buttonholes with or without an eyelet, with straight or cross bartacks, and with knife cuts performed either before or after stitching. This model, however, does not support round buttonholes, distinguishing it from the BH-9820-01 variant.
One of the machine’s strongest features is its modern control panel, which enables users to program stitch length, buttonhole shape and size, cutting style, and sewing speed through a clear and intuitive interface. This ease of programming — without the need for complex mechanical adjustments — makes the BH-9820-02 ideal for short-run production and environments requiring frequent changes in buttonhole styles. With enhanced precision, a larger presser foot lift (16 mm), and the ability to handle a wide range of buttonhole lengths (14–42 mm), the machine is especially suited for sewing on long garment components. A compressed air connection is required for operation.
Key Features:
Programmable Buttonhole Ranges: Supports multiple preset lengths (14–22, 18–26, 22–30, 26–34, 34–42 mm) for flexible garment applications.
Advanced Motor System: Built-in 230V servo motor with stepper motors ensures energy-efficient, reliable, and quiet operation.
No Round Hole Capability: Designed specifically for straight and eyelet buttonholes — not compatible with circular buttonholes.
Fast and Precise: Sewing speed of up to 2,500 stitches per minute, with programmable cutting and stitching sequences.
Easy Digital Control: Touchscreen interface allows seamless adjustment of sewing parameters, ideal for frequent pattern changes.
