printing machine

6-Color Flexographic Roll-to-Roll Printing Machine

High-speed flexographic roll-to-roll printing machine for PP woven and laminated fabric. Features 6 independent printing stations with ceramic anilox rollers, automatic hydraulic throw-off, and inter-color drying system for continuous high-volume production.

The JLRPM-6800BO/6C uses six independent ceramic anilox roller stations to apply up to six colors onto PP woven fabric at up to 100 meters per minute, with inter-color drying between each station to prevent ink bleeding and maintain sharp print registration.

bag making machines

Automatic Printing-Tubing-Cutting-Sewing-Overtape Convention Line

Rey Long's fully integrated bag-making convention line combines four production stages — flexographic printing, tube forming, cutting & sewing, and overtape application — into a single, continuous process. Designed for high-volume PP woven bag production, the line delivers consistent quality with servo-controlled precision and a touch-screen control system.

The JLPTCSM-1300W integrates flexographic printing, tube forming, cutting and sewing, and overtape application into a single continuous process — producing finished PP woven bags at 25 to 40 bags per minute from a raw fabric roll without manual transfer between stages.

High-Speed Multi-Function Stand-Up Zipper Pouch Bag Making Machine

The JL-L-2TZP600 is Rey Long's flagship high-speed, multi-function pouch bag making machine, capable of producing five bag styles — three-side sealing bags, three-side sealing zipper bags, four-side sealing bags, stand-up doypack pouches (with or without zipper) — on a single platform. Built with a 10 mm steel-plate frame, full servo-motor control (Panasonic), and a PLC touch-screen interface, the machine delivers positional accuracy of ≤0.3 mm and speeds up to 220 pcs/min for three-side sealing bags. Zipper sealing is achieved via ultrasonic wave technology, eliminating heat damage to film. Optional double-unwinding and non-stop accumulator modules maximize uptime for continuous production.

The JL-L-2TZP600 uses full Panasonic servo control and a 4+2 heat-seal group configuration to produce five flexible pouch formats — including doypack stand-up pouches and zipper bags — with 0.3 mm or better positional accuracy at up to 220 pieces per minute.

recycling machines

Eddy Current Non-Ferrous Metal Separator Line

Rey Long's JLECS-1000W is a complete non-ferrous metal separation line combining three stages in one system: a vibratory feeder for material distribution, a high-intensity magnetic drum separator for ferrous removal, and an eddy current magnetic roller for precise non-ferrous metal recovery. Ideal for recycling plants, e-waste processing, and mixed-material sorting.

The JLECS-1000W uses a high-speed rotating rare-earth magnetic rotor to induce eddy currents in non-ferrous metals, generating a repulsive force that ejects aluminum, copper, and brass from mixed material streams without contact.

ai solutions

AI-Powered Machine Intelligence Solutions

Rey Long's AI-Powered Machine Intelligence turns a conventional plastic bag making machine into a self-optimizing production line. Instead of running in the cloud, AI inference happens on edge hardware installed at the machine — delivering real-time decisions with near-zero latency and full offline resilience, and retrofittable onto your existing equipment without a full replacement. The program is built on three field-proven capabilities. First, Operator Expertise Digitization captures the tacit know-how of veteran technicians — fabric and film tension, denier-to-feed-speed torque compensation, humidity-driven anti-static control — and turns it into a model that recommends optimal parameters directly on the HMI, so a new operator can set up the line like a 20-year veteran. Second, High-Speed Computer-Vision Inspection uses a CNN model to catch printing, material, and stitching defects in real time at full machine speed, alerting the operator the moment a recurring fault appears. Third, Dynamic Error Compensation reads Eye-Mark deformation through vision and corrects the servo drives on the fly, tightening cutting and sewing accuracy while driving down scrap. Proven on woven-bag lines, stand-up pouch machines, and flexographic printing machines and integrated through standard industrial protocols (OPC-UA, Modbus, MQTT), it delivers measurable ROI on the equipment you already own.

Rey Long's AI Machine Intelligence embeds edge computing and computer vision directly into plastic bag production lines — detecting defects in real time, digitizing operator know-how, and compensating servo drives to achieve cutting and sewing accuracy below plus or minus 1 mm without cloud connectivity.
