Siruba C007KP-W542-356/CFC/CL/FH/2 – High-Speed Cylinder Bed Coverstitch Machine for Elastic Insertion
The Siruba C007KP-W542-356/CFC/CL/FH/2 is a specialized industrial cylinder-bed coverstitch machine engineered for sewing applications that require the insertion of elastic bands “in tunnel,” a common technique used in manufacturing fitted sheets, lingerie, swimwear, and other stretch garments. This machine is highly regarded for its precision, reliability, and ability to maintain production speed while delivering consistent, high-quality seams.
Designed as a 2- or 3-needle, 5-thread machine with both upper and lower interlooping capabilities, it offers excellent seam strength and stretchability—essential for stretchable and elastic fabrics. The needle gauge is set at 5.6 mm, with an alternative model available featuring a 6.4 mm gauge to suit various product specifications and fabric weights. The machine also includes an option to disable the upper interlooping function, offering additional flexibility depending on the sewing task.
One of the key operational strengths of this model is its high maximum sewing speed of up to 6,000 stitches per minute, enabling manufacturers to maintain high throughput without sacrificing stitch quality. The central lubrication system significantly reduces maintenance time by automatically delivering oil to critical machine parts, ensuring smooth operation and prolonged durability even under heavy production conditions.
The Siruba C007KP-W542-356 is equipped with a fabric edge folder with an integrated elastic band folding and sewing feature. This innovative component allows the elastic band to be securely sewn at the beginning and end of the seam, improving efficiency and seam consistency. The machine also features a mechanical elastic tensioner, which controls the tension of the elastic being fed into the tunnel, preventing puckering or stretching irregularities, thus ensuring the finished garment’s proper fit and aesthetic appeal.
Supporting fabric handling is a rear puller roller system, which assists in smooth material transport after sewing, reducing fabric distortion and operator strain. The ergonomically designed puller ensures steady material feed even at high speeds, which is critical for consistent seam quality in elasticated garments.
Additional benefits of this model include:
Compatibility with various elastic widths and fabric types due to adjustable elastic tension and needle gauge options.
Pneumatic or servo motor control (depending on configuration), offering energy-efficient, precise needle positioning and smooth operation.
Robust construction for durability in demanding industrial environments.
Modular design allowing easy integration of attachments or additional features as required by production lines.
In summary, the Siruba C007KP-W542-356/CFC/CL/FH/2 is an advanced, versatile coverstitch machine tailored for applications requiring elastic insertion “in tunnel,” combining high speed, automation, and precise control to enhance productivity and product quality in the apparel industry.
