Our fully automatic Square Paper Core Making Machine is a professional spiral winding equipment specially developed for mass production of square and rectangular kraft paper cores. Optimized for industrial standardized production, this machine integrates automatic paper unwinding, precise gluing, multi-layer spiral winding, fixed-shape molding, CNC fixed-length cutting and automatic discharging in one streamlined process. It effectively solves common problems of traditional equipment, including irregular square angles, core deformation, burr sections and unstable quality, delivering high-precision, high-strength and consistent square paper cores for global packaging and industrial manufacturing industries.
Different from ordinary round paper core machines, this equipment adopts a customized integral square mandrel and synchronous pressure shaping technology. The exclusive molding structure ensures standard 90° right angles, flat tube surfaces and uniform wall thickness for finished square cores, with no corner warping or body distortion. Equipped with an intelligent constant tension control system, the machine keeps paper feeding stable during high-speed operation, avoiding loose winding and size deviation. Built with heavy-duty thick steel frame and anti-corrosion treatment, the whole machine features strong stability, low noise and 24-hour continuous working capacity, perfectly suitable for long-term industrial batch production.
In terms of production quality, the adjustable uniform gluing system ensures even glue coating and firm lamination between paper layers, making finished paper cores high compression-resistant, tough and free of degumming. The high-precision alloy cutting unit delivers smooth, burr-free sections with a cutting tolerance within ±1.5mm, eliminating secondary trimming. The matched dust collection device ensures a clean workshop environment, meeting international environmental protection standards. This machine supports multiple raw materials such as kraft paper, recycled paper and coated paper, covering square core side lengths of 10–100mm and customizable lengths up to 2500mm.
Widely applicable across industries, the produced square paper cores are ideal for gift box reinforcement, carton support, cosmetic and food packaging, as well as cable winding, hardware protection and craft packaging. With modular structure design, the equipment is easy to maintain with low operation costs. We provide complete after-sales support including installation guidance, operational training, one-year warranty and lifelong technical service, helping customers achieve stable and high-efficiency production.
