If you are searching for a high-output, stable and precise CNC paper tube machine for your paper core manufacturing factory, our 4 heads CNC paper tube machine with multi-knife spiral cutting system is the ideal upgrade solution to replace outdated single-head and double-head spiral paper tube winding equipment. This automatic spiral paper tube making machine integrates CNC servo control, four-station synchronous winding and online multi-knife cutting, greatly lifting hourly output while keeping consistent tube roundness, uniform wall thickness and clean cutting edges, which makes it popular among paper converting, textile, packaging and tape core producers worldwide.

Traditional spiral paper tube machines usually run only one or two winding heads at the same time. When order volumes surge, manufacturers face bottlenecks: low production speed, frequent dimension deviation, heavy manual sorting and high paper waste rate. Our 4 heads CNC paper tube winding machine solves these pain points directly. Four independent winding stations work in parallel under one unified CNC control program. Operators set inner diameter, wall thickness, paper layer count, target length and production speed on the touchscreen HMI. The CNC system synchronizes paper feeding, glue spreading, spiral winding, traction and multi-knife cutting automatically, no frequent manual adjustment required during continuous running.

The multi-knife cutting module is one of the core upgrades of this CNC paper tube machine . Unlike single-blade cutters that only finish one cut per cycle, the built-in multi-knife assembly carries out fixed-length cutting and edge trimming online while tubes keep moving forward. Servo tracking cutting guarantees tight length tolerance, cutting burrs are minimized, and finished paper cores need little secondary polishing. It supports cutting multiple finished tubes from one long spiral blank in a single pass, reducing idle time between cuts and boosting material utilization. For factories making mixed-size paper cores in one shift, the CNC system stores multiple production recipes, and users can switch between different tube specifications within minutes, which brings huge flexibility for custom orders.

In terms of production range, this spiral paper tube winding machine covers widely used industrial paper core sizes. It can produce spiral paper tubes with inner diameter from 30 mm to 200 mm, wall thickness from 1 mm to 15 mm, adjustable paper layers from 3 layers up to 26 layers, and cutting length from 1 meter to 5 meters. Running speed can be adjusted between 3 m/min and 30 m/min according to paper quality and tube strength requirements. It works well with kraft paper, recycled paper, coated paper and other raw paper rolls, so you can produce textile yarn paper cores, BOPP tape cores, plastic film roll cores, label cores, printing roll cores, composite can bodies and construction insulation paper tubes on the same CNC paper tube machine.

Reliability is critical for 24-hour continuous paper tube workshops. The frame of our 4 heads CNC paper tube machine adopts heavy-duty welded steel structure, processed by annealing treatment to avoid deformation after long-time vibration. Key transmission parts use hardened gears and precision linear guide rails. The glue system features adjustable glue flow and uniform spreading, preventing glue overflow, dry spots or weak bonding that cause tube delamination. All servo motors, CNC controllers and sensors adopt well-known brand components, lowering failure rate and extending service life. Safety interlock protection covers cutter area, paper feeding zone and machine door; the machine triggers emergency stop once abnormal jamming happens, protecting operators and reducing crash loss.

Compared with buying two sets of double-head spiral paper tube machines, investing in one 4 heads CNC paper tube machine saves workshop space, reduces total power consumption and cuts labor cost. One skilled worker can supervise the whole machine, load raw paper rolls and collect finished tubes, instead of tending multiple separate winding lines. The built-in production counter records running meters, finished tube quantity and alarm logs, helping plant managers track output and analyze downtime easily. Data feedback from the CNC control system also helps stabilize quality for mass export orders, which is very valuable for paper core suppliers serving overseas packaging and textile clients.

This multi-knife spiral paper tube winding machine supports customization to match local factory conditions. We can adjust mandrel sizes, cutter quantity, feeding width and voltage (380V 50Hz, 400V 60Hz or other regional standards) based on customer drawings and sample tubes. Full CE certification is available for EU, Southeast Asia, Africa and Middle East market import clearance. Our factory provides one-year warranty, lifetime technical support, remote CNC parameter debugging and on-site installation training. After-sales team supplies spare parts fast, so your CNC paper tube machine will not stay idle for long waiting for accessories.

Many paper tube manufacturers upgrade to this 4 heads CNC spiral winding machine when they receive big bulk orders of tape cores, film cores and textile cores. They report 2.5–3.5 times higher output than old double-head machines, less waste from uneven cutting, and fewer customer complaints about crooked tubes and uneven ends. If your factory is struggling with low efficiency, unstable cutting quality or rising labor expense, this CNC paper tube machine is a cost-effective upgrade path.

To sum up, the 4 Heads automatic paper core tube making machine with multi-knife spiral cutting is a high-efficiency, flexible and stable automatic paper core production line. It combines CNC intelligent control, four-station parallel winding and online multi-knife cutting to meet high-volume, mixed-spec paper tube production demands. Whether you run a small new paper core workshop or a large industrial packaging tube factory, this spiral paper tube winding machine improves productivity, controls production cost and delivers consistent finished tube quality, helping you win more orders in the competitive paper converting industry.
