With a heavy-duty fabricated structure, Mitsubishi-based automation, servo-controlled cutting mechanisms, and an integrated sewing arrangement, Rentech provides a practical industrial solution for continuous bag conversion requirements. Designed for Modern Leno Bag Manufacturing Leno bags are widely used for packaging agricultural products such as onions, potatoes, garlic, fruits, and vegetables. Their open-mesh construction provides ventilation, making them suitable for applications where air circulation is important. Converting Leno fabric into finished bags requires controlled feeding, accurate cutting, proper folding, and uniform stitching. The Rentech Automatic Leno Bag Cutting & Stitching Machine combines these operations in one integrated production line. It is designed to handle different fabric widths and bag lengths while maintaining controlled material movement throughout the process. Integrated Automatic Production Process The machine performs multiple conversion operations through an integrated arrangement. Fabric Unwinding: The fabric roll is mounted on the unwinding unit, with a maximum roll diameter of 1200 mm and roll capacity up to 700 kg. Fabric Tension Control: A dancing roller arrangement with an aluminium fin roll helps maintain controlled fabric movement during operation. Automatic Fabric Guiding: The electronic web guiding system uses a linear actuator to maintain fabric alignment. Length Measurement and Feeding: Servo-controlled pulling rollers provide controlled fabric feeding according to the required bag length. Automatic Cutting: The cutting system supports regular and zigzag heat cutting, along with a servo-based cold cutting arrangement. Printed Fabric Registration: A SICK colour mark sensor detects printing marks for accurate cutting registration on printed laminated fabric. Automatic Folding: The folding arrangement supports single-fold and double-fold configurations. Bag Stitching: The integrated Model 502 HD sewing machine provides consistent stitching for finished bag formation. Bag Collection: The conveyor arrangement delivers finished bags for collection and further handling. Advanced Cutting Technology Cutting accuracy plays an important role in maintaining consistent bag dimensions and minimizing fabric wastage. The Rentech automatic machine incorporates servo-based cold cutting technology along with high-quality heat-cutting knives. Key cutting features include: - Servo-based cold cutting mechanism. - Regular and zigzag type heat-cutting knife. - Mouth opener device. - Cutting length accuracy of ±1 mm. - Adjustable cutting length from 17 inches to 55 inches. - Colour mark detection for printed laminated fabric. The combination of cutting options allows manufacturers to select the appropriate cutting method according to fabric characteristics and production requirements. Intelligent Mitsubishi Automation System The machine is equipped with a Mitsubishi-based automatic control system designed for coordinated machine operation. The 10-inch touchscreen HMI provides an operator-friendly interface for machine control and production settings. Automation highlights include: - Mitsubishi PLC control system. - 10-inch touchscreen HMI. - Mitsubishi servo motors. - Servo-controlled pulling roller. - Servo-controlled clipper mechanism. - Servo-based cold cutting. - Mitsubishi AC drives for motor control. - Integrated automatic operating system. The automation arrangement helps coordinate fabric feeding, cutting, and other conversion operations while reducing dependence on manual machine adjustments. High-Precision Servo Motor Technology Servo motor technology plays an important role in controlling fabric movement and cutting operations. The machine incorporates the following Mitsubishi servo motors: - Pulling Roller Motor: 1.5 kW Mitsubishi Servo Motor. - Clipper Motor: 1.5 kW Mitsubishi Servo Motor. - Cold Cutting Motor: 0.75 kW Mitsubishi Servo Motor. These servo-driven mechanisms provide controlled movement and support accurate cutting and synchronized machine operations. Reliable Folding and Stitching Arrangement The folding and stitching section is designed to produce properly finished Leno bags with consistent folding and stitching quality. The machine features a Model 502 HD sewing machine and an adjustable folding arrangement. Key features include: - Model 502 HD sewing machine. - Single-fold and double-fold options. - Adjustable folding width of 16–30 mm for single folding. - Adjustable stitching range of 5–10 mm. - Stitch density of 10–20 stitches per 100 mm. The adjustable stitching and folding settings allow manufacturers to configure the machine according to their bag finishing requirements. Heavy-Duty Industrial Construction A stable machine structure is important for reliable operation in continuous production environments. The Rentech machine is constructed with a 6 mm heavy fabricated body structure, designed to provide mechanical stability during operation. Additional construction features include: - Heavy-duty fabricated machine body. - Industrial-grade drive components. - WEG three-phase induction motors. - Bonfiglioli gearbox arrangements on specified drives. - Aluminium fin roller arrangement. - Integrated conveyor system. - Industrial pneumatic components. The machine is designed for demanding industrial bag conversion applications. Production Capacity and Operational Efficiency The machine offers an indicative production capacity of 25–40 bags per minute, depending on fabric type, bag dimensions, stitch density, number of folds, and operating conditions. Its automatic feeding, cutting, folding, and stitching arrangement helps streamline the production process and reduce repetitive manual operations. Only one operator is specified for machine operation under the stated configuration. Actual production output depends on material characteristics, machine settings, and operating conditions.
