The Siruba DL7500-RNM1-48-16 is a highly advanced single-needle lockstitch sewing machine designed for precise sewing of light to medium-weight materials. Equipped with a needle-toothed feed system and an integrated fabric edge trimming mechanism (nipper), this machine delivers clean, professional seams ideal for applications requiring exceptional precision, such as attaching flaps, cuffs, collars, and other detailed garment components. The edge trimming device can be rapidly enabled or disabled during operation, allowing operators flexibility without interrupting the workflow.
This model features energy-efficient servo motors—two stepping motors independently control fabric feeding, thread trimming, and presser foot lifting—ensuring smooth, consistent sewing performance with enhanced energy savings. The machine’s control panel and servo motor controller are integrated into the head for ergonomic operation and streamlined use. The machine’s closed lubrication system protects internal components from oil contamination, prolonging maintenance intervals and boosting machine longevity even under intensive production conditions.
Automatic functions improve efficiency and stitch quality. These include automatic thread trimming, backtacking (locking) at the beginning and end of stitching, needle positioning for exact stitch placement, programmable decorative stitch patterns, parameter customization for stitch density and length, and automatic presser foot lifting. The machine supports a maximum sewing speed of 4,500 stitches per minute, with a stitch length of up to 5 mm, and a presser foot lift height of 11 mm, suitable for handling a wide variety of garment materials.
Technical specifications include adjustable edge trimming widths (standard 4.8 mm, optional 3.2 mm or 6.4 mm) to suit different fabric types and design requirements. The machine utilizes DBx1 needles and operates on a 230V power supply. These combined features make the Siruba DL7500-RNM1-48-16 an efficient and reliable choice for garment manufacturers seeking high precision and productivity in industrial sewing operations.
