GK26-22 Portable Bag Closing Machine
Engineered for reliability, speed, and continuous operation, the GK26-22 Portable Bag Closing Machine is a double-thread industrial sewer designed for sealing bags and sacks across agricultural, grain handling, chemical, and packaging facilities. Specially built for high-demand environments, it creates a secure, tamper-resistant seam on filled rice sacks, grain bags, animal feed pouches, woven polypropylene (PP), multi-wall paper, burlap, jute, and canvas containers. Featuring an ergonomic insulated grip and an automatic thread cutter, it maximizes packaging speed while reducing operator fatigue.
Key Features & Benefits
Double-Thread Chain Stitch (Type 401): Produces a strong, tight double-thread chain seam that prevents leakage of fine grains like rice, flour, and seed mixtures under heavy transport conditions.
Heavy-Duty Drive Mechanism: Built with hardened alloy cams, sealed ball bearings, and steel connecting rods to ensure long operational lifespan in dusty agricultural environments.
Integrated Thread Cutter: Automatic mechanical thread trimmer cuts the thread chain instantly after each sack pass to keep production lines moving rapidly.
Semi-Automatic Lubrication: Built-in oil pump distribution system delivers direct lubrication to main friction points with a simple push button, minimizing friction wear and maintenance downtime.
Ergonomic Safety Design: Heat-insulated plastic handle provides a secure grip, vibration isolation, and protection against electrical surges during extended operation.
Versatile Material Handling: Easily pierces through thick multi-ply materials up to 8 mm total thickness without dropping stitches or bunching material.
