Wenzhou Sanhui Machinery Manufacturing Co., Ltd. is one of the leading manufacturers and suppliers of paper roll slitter in China. With abundant experience, we are able to meet the needs of the majority of our customers. Welcome to wholesale customized paper roll slitter at competitive price from our factory.
The paper roll slitter machines lies in their ability to "break down large batches into smaller segments" and provide "high-precision customization": they decompose wide master rolls at high speeds (up to 600 m/min) into narrow finished products; through precise width tolerance control (±0.1 mm), they eliminate any paper misalignment during final high-speed printing, thereby serving as a physical guarantee for achieving a high product yield rate.
Unwinding Unit
Structure：The paper roll slitting machine is a hydraulic shaftless cone-top clamping mechanism that can automatically lift mother rolls weighing 3 to 5 tons.
Key components：Brake (magnetic powder/pneumatic), used to provide unwinding resistance and enable zero-speed start in conjunction with a variable frequency motor
Guiding & Pulling Unit
Core technology：Ultrasonic or CCD photoelectric misalignment sensors detect the position of the paper edge to ensure that the material fed into the cutting unit remains straight.
Edge Trimming Unit
Structure：Install a high-pressure fan and waste suction pipe at the end of the paper roll slitter machine
Key Process Points：The waste edge width is typically set between 10 to 20 mm. After being cut, it is immediately sucked into the pipeline, transported to the baler for compression, ensuring that no paper scraps fly around in the workshop.
Rewinding Unit
Structure：Multiple sets of air-inflated shafts enable non-stop roll changing (flying splice).
Core Technology：The paper roll slitter machines tapered Tension Decrement Control. As the roll diameter increases, the winding tension gradually decreases according to a preset curve, ensuring that the finished large roll has tight inner layers and loose outer layers, thus preventing internal wrinkling or outer layer damage.
We support customers in sending actual materials for trial cutting on the machine. By examining the cut edges and rewinding results, we then finalize the equipment configuration to avoid purchasing machines that are incompatible with their raw materials.
