If you are searching for a reliable automatic paper tube making machine   to expand your industrial paper core production, our PLC controlled kraft paper core making machine delivers stable winding performance, flexible diameter customization and consistent finished tube quality for packaging, converting, textile and film industries. As a professional custom diameter paper tube machine, it is engineered for spiral kraft paper core forming, supporting variable inner diameter, wall thickness and length adjustment to match diverse end-user requirements, which makes it one of the most versatile paper tube machines for medium and large paper core factories worldwide.

The kraft paper core making machine adopts advanced PLC programmable control system paired with HMI touch screen, allowing operators to set winding speed, paper ply count, glue coating volume, cutting length and tension parameters directly on the panel. All production data can be stored and recalled for repeated batch production, greatly reducing manual setting errors and stabilizing the roundness and compression strength of kraft paper cores. Compared with traditional mechanical paper core winding equipment, this PLC controlled kraft paper core making machine features real-time fault alarm, automatic counting and synchronous servo cutting, minimizing downtime and scrap rate during continuous running. For paper core manufacturers handling frequent specification changes, the custom diameter paper tube machine stands out because we can adjust the mandrel and winding module to produce small, medium and large kraft paper cores, instead of purchasing separate machines for different sizes.

This Kraft paper core making machine works with kraft paper, recycled kraft paper and composite paper plies. It forms spiral wound kraft paper cores with uniform glue distribution, no gaps, no wrinkles and high vertical compression resistance. The glue system supports single-side or double-side gluing as option, with stainless steel glue tank and adjustable glue scraper to avoid glue overflow and save adhesive cost. Tension control is a key part of our kraft paper core making machine; stable tension keeps every layer of kraft paper tightly laminated, so finished paper cores will not deform under stacking or rewinding load. The finished kraft paper cores are widely used as stretch film cores, adhesive tape cores, textile yarn cores, aluminum foil cores, paper can cores, label roll cores and mailing tube cores, covering packaging, plastic converting, textile, printing and food packaging sectorszjchuangfe

What separates our custom diameter paper tube machine from standard kraft paper core making machines is its high customization flexibility. Standard models cover common inner diameter range, and we support non-standard mandrel customization for special large diameter or micro-size kraft paper cores. Wall thickness can be adjusted by changing paper layer quantity, while finished tube length is programmable via PLC for automatic servo tracking cutting. Customers can also choose single-head, double-head or multi-head winding configuration according to target output capacity. The frame of the kraft paper core making machine uses heavy-duty welded steel structure, anti-vibration design to maintain precision under long-hour high-speed operation. Main electrical components adopt well-known brand inverters, servo motors and PLC modules for stable performance and easy spare parts supply in overseas markets.

Operation and maintenance of this PLC controlled kraft paper core making machine are friendly for factory teams. The touch screen interface uses simple graphic menus; new operators can master basic operation within short training. Safety protection covers emergency stop button, protective cover and overload protection function to meet international safety standards. Our kraft paper core making machine can work as a standalone unit, or connect with paper unwinder, paper slitter and automatic paper core stacker to build a full automatic kraft paper core production line. For small startup workshops and mature paper core plants, the custom diameter paper tube machine offers scalable production capacity, helping buyers start kraft paper core business or upgrade old paper core making lines without replacing the whole workshop layout.

Many buyers look for a kraft paper core making machine that balances price, stability and customization. Cheap basic paper tube machines often struggle with diameter consistency, unstable tension and frequent breakdowns when switching sizes. Our PLC controlled kraft paper core making machine solves these pain points by digital closed-loop control. Every adjustment is recorded digitally, so you can replicate the same high-quality kraft paper core every batch. When your customer orders change from thin tape cores to heavy-duty industrial kraft cores, you only need to change the mandrel and modify PLC parameters on the custom diameter paper tube machine, which shortens specification changeover time and improves production scheduling efficiency.

We provide full after-sales support for every  automatic paper tube machine: operation manual, wiring diagram, operation video, remote online debugging and optional overseas engineer commissioning service. Before shipment, every custom diameter paper tube machine will run a full load test to check winding roundness, cutting accuracy and PLC response. We also support modification requests for voltage, frequency and auxiliary structures to fit different regional power conditions. Whether you plan to produce kraft paper cores for local packaging factories or export finished paper tubes, this kraft paper core making machine is a solid automation investment to boost output, lower labor cost and improve product competitiveness.

In summary, if you need an automatic, flexible and low-maintenance kraft paper core making machine, our PLC controlled custom diameter paper tube machine is your ideal option. It combines intelligent PLC control, precision spiral winding and full size customization, helping paper core manufacturers produce premium kraft paper cores for global markets.
